Tauri vs Electron: 3.2MB vs 85MB Bundle [2026]

Electron 44 shipped on August 25, 2026 running on Chromium M152, and it still bundles a full browser engine inside every installer it produces. Tauri 2.12.0 shipped a month later, on September 26, 2026, and it still leans on the operating system’s own WebView instead of dragging Chromium along for the ride. That one architectural choice is the reason this comparison keeps coming up in developer forums, Discord servers, and Stack Overflow threads: the gap between the two frameworks shows up the moment you run a build.

This tutorial does not just list specs. It walks through building the identical small desktop app, a notes manager with local file storage, in both Tauri and Electron, then measures the installer size, idle RAM, and cold start time on the same machine so you can see the difference instead of taking anyone’s word for it. By the end you will have two working projects, a side by side benchmark table, and enough context to decide which framework fits your next build.

Both frameworks solve the same underlying problem: teams want to reuse web development skills, HTML, CSS, and JavaScript, to ship a native-feeling desktop app without maintaining separate Swift, C++, or C# codebases per platform. Where they diverge is in how much of the browser they drag along to make that happen, and that single decision shapes everything from your installer size to your security review to how your CI pipeline needs to be structured. The sections below cover all of it in order, starting with the setup and ending with a decision framework you can actually apply to your next project.

Prerequisites and Versions You Need

Before touching either framework, get your machine ready. Both tutorials assume a reasonably current desktop or laptop running Windows 10/11, macOS 13 or later, or a mainstream Linux distribution with a modern WebKitGTK package available.

Node.js 20 LTS or newer (both frameworks’ tooling runs on Node)
Rust 1.80 or newer, installed through rustup, for the Tauri build (Tauri 2.11 and 2.12 both require a current stable toolchain)
Tauri CLI 2.12.0, installed via Cargo or npm
Electron 44.0.0 (the current stable line as of October 2026, built on Chromium M152)
A code editor, a terminal, and roughly 6 GB of free disk space for both toolchains combined
On Linux: webkit2gtk-4.1 and related system packages for Tauri; on Windows: the WebView2 runtime, which ships with Windows 11 by default

Tauri 3 exists only as an alpha release (alpha.5 as of mid October 2026) and is not production ready, so every step below targets the Tauri 2.x line, specifically 2.12.0. On the Electron side, version 45 was expected around October 20, 2026, but 44.0.0 is the version this tutorial builds against since it is the version most teams have in production today.

Step 1: Understand the Architecture Difference Before You Write Any Code

Everything else Every benchmark number and every troubleshooting tip, traces back to one decision each framework made early on. Electron packages Chromium and a Node.js runtime inside your app. That means your app carries its own browser everywhere it goes, which guarantees rendering consistency across Windows, macOS, and Linux but also means every Electron app pays a fixed tax in disk space and RAM before a single line of your own code runs.

Tauri instead calls into the WebView already installed on the host operating system, WebView2 on Windows, WebKit on macOS, and WebKitGTK on Linux, and pairs it with a Rust backend instead of Node.js. Wes Bos, the web developer and co-host of the Syntax podcast, has described the result bluntly: “This is the Rust version of Electron.” His co-host Scott Tolinski put the tradeoff in plainer terms during the same episode, pointing out that Tauri relies on “the web views that come in baked into your OS” rather than shipping a browser inside the app.

That single difference, bundled browser versus OS-provided WebView, cascades into every number you will see in this article: installer size, memory footprint, startup time, and even how security patches get delivered.

Step 2: Install Node.js, Rust, and the Platform Dependencies

Start with Node.js since both projects need it. Download the current LTS release from the official Node.js site and verify the install.

node --version
npm --version

Next, install Rust through rustup, which Tauri needs for its backend compilation step. Electron does not need this, but install it now so both environments are ready before you start comparing build times.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"
rustc --version
cargo --version

On Linux, install the system libraries Tauri’s WebView wrapper depends on. On Ubuntu or Debian-based distributions that means a handful of apt packages for WebKitGTK, AppIndicator, and the Rust Server Virtual Machine dependencies. On Windows and macOS, skip this step; the WebView components Tauri needs are either pre-installed or fetched automatically by the CLI.

sudo apt update
sudo apt install libwebkit2gtk-4.1-dev build-essential curl wget file \
  libxdo-dev libssl-dev libayatana-appindicator3-dev librsvg2-dev

Step 3: Scaffold the Tauri Project

With Rust and Node ready, scaffold the Tauri app using the official create command. This generates a project with a Rust backend in src-tauri and a plain web frontend in src.

npm create tauri-app@latest notes-tauri
cd notes-tauri
npm install

Choose the vanilla JavaScript template when prompted, since the goal here is an apples to apples comparison with Electron rather than a framework bake-off between React and Svelte. Once the install finishes, confirm the dev environment runs.

npm run tauri dev

A native window should open within a few seconds, rendered by your OS’s WebView rather than a bundled browser. If the window opens and shows the default Tauri welcome page, the Rust toolchain and WebView dependencies are wired up correctly.

Step 4: Scaffold the Electron Project

In a separate directory, set up the Electron equivalent. Electron does not ship a single official scaffolding tool the way Tauri does, so the fastest path is a manual package.json plus the electron dependency.

mkdir notes-electron && cd notes-electron
npm init -y
npm install [email protected] --save-dev

Add a start script to package.json so you can launch the app with a single command, and set the main entry point to a file named main.js.

{
  "name": "notes-electron",
  "version": "1.0.0",
  "main": "main.js",
  "scripts": {
    "start": "electron ."
  },
  "devDependencies": {
    "electron": "44.0.0"
  }
}

Step 5: Write the Electron Main Process

Electron apps need a main process file that creates the window and manages the app lifecycle. This is the piece that does not exist in a Tauri project in the same form, since Tauri’s Rust backend plays that role instead.

const { app, BrowserWindow, ipcMain } = require('electron')
const path = require('path')
const fs = require('fs')

function createWindow () {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
      contextIsolation: true,
      nodeIntegration: false
    }
  })
  win.loadFile('index.html')
}

app.whenReady().then(createWindow)

ipcMain.handle('save-note', async (event, text) => {
  fs.writeFileSync(path.join(app.getPath('userData'), 'note.txt'), text)
  return true
})

ipcMain.handle('load-note', async () => {
  const file = path.join(app.getPath('userData'), 'note.txt')
  return fs.existsSync(file) ? fs.readFileSync(file, 'utf-8') : ''
})

Note the contextIsolation and nodeIntegration flags. Leaving nodeIntegration enabled would expose Node APIs directly to your renderer’s JavaScript, which is the exact mistake Electron’s own security documentation warns against. Keep contextIsolation on and route anything privileged through a preload script and ipcMain handlers, as shown here.

Step 6: Write the Tauri Rust Backend Commands

In the Tauri project, the equivalent logic lives in Rust, inside src-tauri/src/main.rs (or lib.rs in newer scaffolds). Tauri commands are explicitly exposed functions the frontend can call, and nothing beyond what you list in a command is reachable from JavaScript at all.

use std::fs;
use tauri::Manager;

#[tauri::command]
fn save_note(app: tauri::AppHandle, text: String) -> Result<(), String> {
    let dir = app.path().app_data_dir().map_err(|e| e.to_string())?;
    fs::create_dir_all(&dir).map_err(|e| e.to_string())?;
    fs::write(dir.join("note.txt"), text).map_err(|e| e.to_string())
}

#[tauri::command]
fn load_note(app: tauri::AppHandle) -> Result {
    let dir = app.path().app_data_dir().map_err(|e| e.to_string())?;
    let file = dir.join("note.txt");
    if file.exists() {
        fs::read_to_string(file).map_err(|e| e.to_string())
    } else {
        Ok(String::new())
    }
}

fn main() {
    tauri::Builder::default()
        .invoke_handler(tauri::generate_handler![save_note, load_note])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Notice there is no equivalent of nodeIntegration to worry about here. Tauri’s capability system denies frontend access to anything on the system by default, and you opt individual commands in rather than opting a whole runtime out. That is the design choice Daniel Thompson-Yvetot, one of Tauri’s co-creators, pointed to when discussing security patching on the devtools.fm podcast, noting that it is “safer to patch security vulnerabilities, because it’s handled by the operating system instead of you having to bundle your application again because Chromium has some issue.”

Step 7: Build the Shared Frontend HTML and JavaScript

Both apps can use nearly identical frontend code since both expose their backend functions through a JavaScript bridge. Here is the HTML and script for the Electron version, saved as index.html in the project root.

<!DOCTYPE html>
<html>
<body>
  <textarea id="note" rows="10" cols="50"></textarea><br>
  <button id="save">Save</button>
  <script src="renderer.js"></script>
</body>
</html>

Add a preload.js file to expose the ipcRenderer calls safely to the page, and a renderer.js to wire up the button.

// preload.js
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld('notesAPI', {
  save: (text) => ipcRenderer.invoke('save-note', text),
  load: () => ipcRenderer.invoke('load-note')
})

// renderer.js
window.addEventListener('DOMContentLoaded', async () => {
  const note = document.getElementById('note')
  note.value = await window.notesAPI.load()
  document.getElementById('save').addEventListener('click', () => {
    window.notesAPI.save(note.value)
  })
})

For Tauri, the frontend in src/index.html calls window.__TAURI__.core.invoke instead of ipcRenderer, but the shape of the code is almost the same, which is one of the underrated strengths of both frameworks: your web development skills transfer directly.

const { invoke } = window.__TAURI__.core

window.addEventListener('DOMContentLoaded', async () => {
  const note = document.getElementById('note')
  note.value = await invoke('load_note')
  document.getElementById('save').addEventListener('click', () => {
    invoke('save_note', { text: note.value })
  })
})

Step 8: Run Both Apps in Development Mode

Launch the Electron app first.

npm start

Then switch to the Tauri project directory and run its dev command.

npm run tauri dev

You will likely notice the Tauri window appears faster the second time you run it, since Rust compiles the backend once and caches the build, while Electron’s startup overhead is more consistent run to run because it is mostly tied to spinning up Chromium rather than compiling anything.

Developer Experience: Hot Reload, Debugging, and IDE Support

Before moving on to packaging, it is worth spending a few minutes in each project’s dev loop, since this is where you will live for most of a real build. Tauri’s dev server hot-reloads the frontend instantly through Vite or whichever bundler the scaffold picked, exactly the way a normal web project would. Rust changes are a different story: editing src-tauri/src/main.rs triggers a recompile, and that recompile is not instant. On a first build you are looking at anywhere from 30 seconds to a couple of minutes depending on your machine, though incremental builds after the first one drop sharply once Cargo’s build cache warms up.

Electron’s dev loop skips that compile step entirely, since main.js, preload.js, and renderer.js are all plain JavaScript that the V8 engine inside Chromium just runs. Restarting the app after a main process change is close to instant, and you get Chromium’s full DevTools for free, inspecting the renderer exactly like you would a Chrome tab, complete with the Elements panel, Network tab, and Performance profiler your team probably already knows.

Debugging Tauri’s Rust side requires a different toolkit. VS Code‘s rust-analyzer extension plus the CodeLLDB debugger extension let you set breakpoints directly in main.rs, which is a workable setup but not as immediately familiar to a JavaScript-only developer as opening Chrome DevTools. The frontend half of a Tauri app still debugs through the same WebView inspector tools (right-click, Inspect Element works on most platforms), so day to day UI debugging feels close to identical between the two frameworks. The real difference shows up only when a bug lives in the backend logic, where Electron developers stay inside familiar Node.js debugging and Tauri developers need at least working knowledge of Rust’s error types and the Result pattern used throughout the Step 6 code above.

Step 9: Package Production Builds for Both Apps

This is where the headline numbers Actually come from. Build the Tauri app for release.

npm run tauri build

Tauri compiles the Rust backend in release mode and produces a platform-native installer (an .msi or .exe on Windows, a .dmg or .app on macOS, a .deb, .rpm, or AppImage on Linux) in src-tauri/target/release/bundle.

For Electron, add a packaging tool such as electron-builder, since the bare electron package does not produce distributable installers on its own.

npm install electron-builder --save-dev
npx electron-builder --win --mac --linux

Electron-builder bundles Chromium, Node.js, and your app code into a single installer per platform. This is also the step where you will watch the Electron build artifact balloon well past what the Tauri build produces, for reasons that come down entirely to what each framework packs inside the installer.

Step 10: Measure Installer Size, Memory Use, and Startup Time

With both production builds sitting on disk, run the comparison that actually matters to end users: how big is the download, how much RAM does it eat sitting idle, and how long before the window is usable.

Check installer size directly from the file system.

# macOS / Linux
du -h notes-tauri/src-tauri/target/release/bundle/dmg/*.dmg
du -h notes-electron/dist/*.dmg

# Windows PowerShell
Get-Item .\notes-tauri\src-tauri\target\release\bundle\msi\*.msi | Select Length
Get-Item .\notes-electron\dist\*.exe | Select Length

Check idle memory usage with your OS’s task manager (Activity Monitor on macOS, Task Manager on Windows, or htop on Linux) after launching each app and letting it sit idle for 30 seconds. For a repeatable cold-start timing test, wrap the launch command in a simple timer.

# macOS / Linux example
time ./notes-tauri/src-tauri/target/release/notes-tauri
time ./notes-electron/dist/notes-electron

Independent benchmarks run through 2026 consistently show the same pattern this hands-on test will reproduce, even if the exact numbers shift depending on hardware and how many windows an app opens.

Metric	Tauri 2.12	Electron 44	Source test
Hello-world bundle size	3.2 MB	85 MB	Six-window comparison benchmark
Complex app bundle size (6 windows)	8.6 MB	244 MB	Six-window macOS comparison
Idle memory, single window	~42 MB	~168 MB	Single-window idle benchmark
Idle memory, six windows (macOS)	~172 MB	~409 MB	Six-window macOS comparison
Cold start time	~380 ms	~1,420 ms	Cold-start benchmark
GitHub stars (approximate, 2026)	88,000 to 107,000	107,000 to 121,000	Repository snapshots, 2026

Treat these as representative figures from named tests rather than a single universal benchmark. Your own numbers from Step 10 will vary with CPU, OS, and how much your app actually does, but the direction of the gap, Tauri smaller and lighter, Electron heavier but more predictable across platforms, holds consistently across every public test run in 2026.

Step 11: Add File System Access Safely in Each Framework

Most real desktop apps need more than reading and writing one text file, so this step extends the notes app to list, open, and save multiple files, which is also where the two security models diverge the most visibly.

In Tauri, add the fs permission scope to src-tauri/capabilities/default.json, limiting exactly which directories your app can touch.

{
  "identifier": "default",
  "windows": ["main"],
  "permissions": [
    "core:default",
    {
      "identifier": "fs:allow-app-write",
      "allow": [{ "path": "$APPDATA/*" }]
    }
  ]
}

Anything outside that declared scope simply fails at the Rust layer, even if a bug or a malicious dependency tries to reach further. In Electron, the equivalent safety net is entirely on you as the developer: keep nodeIntegration disabled, validate every path you pass into fs calls inside main.js, and never let the renderer construct file paths that cross into ipcMain handlers unchecked.

Step 12: Test Auto-Update Behavior

Shipping an app once is the easy part. Keeping it updated across a user base is where the two frameworks’ maturity gap is most visible. Electron’s ecosystem has had updater tooling such as electron-updater for years, with broad real-world coverage across Windows, macOS, and Linux delta updates.

npm install electron-updater
# in main.js
const { autoUpdater } = require('electron-updater')
autoUpdater.checkForUpdatesAndNotify()

Tauri ships an official updater plugin as well, configured through tauri.conf.json, and it benefits from the same small-bundle advantage: update payloads tend to be smaller because there is less to patch.

cargo add tauri-plugin-updater
npm install @tauri-apps/plugin-updater

Test both updater paths against a staging release channel before pointing them at production, since a broken auto-updater is one of the few bugs that can strand users on an old, unpatched build with no easy recovery path.

CI/CD and Cross-Compilation for Both Frameworks

Shipping to three desktop operating systems from one continuous integration pipeline works differently for each framework, and it is worth planning for before you commit to either one. Electron builds are comparatively forgiving about cross-compilation: electron-builder can produce a Windows installer from a Linux CI runner in many configurations, since it is mostly packaging pre-built Electron binaries rather than compiling anything from source. Most teams still run separate macOS, Windows, and Linux runners anyway to handle code signing and notarization correctly, but the packaging step itself tolerates cross-building reasonably well.

Tauri’s Rust backend makes cross-compilation more particular. Compiling a Windows .msi from a Linux runner, or a macOS .dmg from anywhere other than macOS, generally requires the correct Rust target toolchain installed and, for Apple targets, access to Apple’s own build tooling, which in practice means you need a macOS runner for macOS builds no matter what. GitHub Actions‘ hosted runners cover all three operating systems directly, and the official tauri-action GitHub Action handles most of the matrix build configuration for you, building all three installers in parallel jobs rather than one sequential pipeline. Here is a minimal workflow outline for that setup.

# .github/workflows/release.yml (excerpt)
strategy:
  matrix:
    platform: [macos-latest, ubuntu-22.04, windows-latest]
runs-on: ${{ matrix.platform }}
steps:
  - uses: actions/checkout@v4
  - uses: dtolnay/rust-toolchain@stable
  - uses: actions/setup-node@v4
    with:
      node-version: 20
  - run: npm install
  - uses: tauri-apps/tauri-action@v0
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Build times are the other factor to plan around. A Rust release build with full optimizations takes noticeably longer than packaging an Electron app, often several minutes per platform in CI versus closer to one minute for an Electron packaging step, because the compiler is doing real optimization work rather than copying files into an archive. That cost is one-time per release rather than something your end users ever feel, but it does affect how fast your team can ship a hotfix.

Step 13: Decide Which Framework Fits Your Project

With both apps built, packaged, and benchmarked, the decision usually comes down to three questions rather than raw numbers alone.

First, does your team already know Rust, or is the team entirely JavaScript and TypeScript? Tauri’s backend work requires at least basic Rust literacy, which is a real onboarding cost for a team with none. Second, do you need guaranteed rendering consistency across every OS, including older corporate Windows images with outdated WebView2 runtimes? Electron’s bundled Chromium removes that variable entirely, while Tauri depends on whatever WebView version the host OS provides. Third, does your app need to ship to mobile as well as desktop? Tauri 2.x added Android and iOS targets from the same Rust-based project structure, something Electron has no native equivalent for.

Scott Tolinski summed up the core appeal of Tauri on Syntax’s episode covering whether it could replace Electron, saying “the real benefit to using Tauri versus Electron is that it’s not huge. The joke with Electron is you download an entire thing, and we’re running these massive Chrome apps on absolutely every single desktop.” That said, Electron’s maturity, its decade of production hardening inside apps like Visual Studio Code, Slack, and Discord, still buys predictability that a newer framework has to earn over time. Wes Bos put Electron’s tradeoff just as plainly on the same show, noting that “Electron bundles a browser, so it’s easier.”

Common Pitfalls When Switching Between Tauri and Electron

Leaving nodeIntegration enabled in Electron. It is still the default in some older boilerplate and templates floating around, and it exposes Node APIs directly to any script running in your renderer, including third-party content if you ever load remote URLs.
Assuming Tauri’s WebView behaves exactly like Chrome. WebKitGTK on Linux and the OS WebView on Windows and macOS have small but real CSS and JavaScript API differences from Chromium. Test on all three platforms before shipping, not just the one you develop on.
Forgetting to scope Tauri’s capability permissions. A default.json left wide open defeats the entire point of Tauri’s security model. Scope every fs, shell, and http permission to the narrowest path and command your app actually needs.
Underestimating Rust’s learning curve mid-project. Teams sometimes start a Tauri migration assuming “it’s just the backend” and hit the borrow checker hard once they need anything beyond simple file reads and writes.
Not accounting for Electron’s bundle size in CI and CDN costs. A 150 MB to 250 MB installer multiplied across thousands of auto-update downloads adds up fast on a bandwidth bill in a way a sub-10 MB Tauri update does not.
Ignoring WebView2 runtime availability on older Windows machines. Most modern Windows 11 installs include it, but some locked-down corporate images do not, and Tauri apps will fail to launch without it unless you bundle the runtime installer alongside your app.
Comparing benchmark numbers from different app complexity levels. A single-window hello-world Tauri app versus a six-window production Electron app is not a fair comparison. Always benchmark apps of equivalent complexity, as this tutorial does in Step 10.

Expected Output: What You Should See After Each Step

After Step 3, npm run tauri dev should open a native window within 2 to 5 seconds on a typical modern laptop, showing the default Tauri welcome screen with no visible browser chrome. After Step 8, both notes apps should let you type text, click Save, close the app, reopen it, and see the saved text reload automatically. After Step 9, you should have a single installer file per platform in each project’s output directory, roughly a few megabytes for Tauri and tens to low hundreds of megabytes for Electron. After Step 10, your own du -h and Activity Monitor or Task Manager readings should land in the same general range as the benchmark table in Step 10, even if your exact numbers differ by hardware.

Troubleshooting: Fixing the Most Common Build Errors

Tauri build fails with “webkit2gtk not found” on Linux. Install the exact package version your distribution ships, usually libwebkit2gtk-4.1-dev on current Ubuntu and Debian releases; older guides reference 4.0, which may no longer exist in your package manager.
Electron window opens blank/white. Check the DevTools console (Ctrl+Shift+I or Cmd+Option+I) for a Content Security Policy violation or a failed require() call caused by contextIsolation blocking direct Node access from the renderer.
Tauri command invoke() returns “command not found.” Confirm the Rust function name in generate_handler! matches exactly, including highlights versus camelCase, and that you rebuilt the Rust backend after adding the command (npm run tauri dev does not always hot-reload Rust changes).
electron-builder fails with code signing errors on macOS. Unsigned builds still work locally for testing; add CSC_IDENTITY_AUTO_DISCOVERY=false as an environment variable to skip signing during local development.
Tauri app crashes immediately on Windows with no error. Check whether the WebView2 runtime is installed; download and run the Evergreen Bootstrapper from Microsoft if it is missing, which is common on older enterprise Windows images.
npm install electron hangs or times out. Electron’s postinstall step downloads a full Chromium binary per platform, which can be 100+ MB; set the ELECTRON_MIRROR environment variable to a regional mirror if the default download is slow.
Rust compile errors referencing a borrow checker issue you don’t understand. Start by cloning the variable with .clone() if it is small data like a String, then revisit ownership once the app compiles; it is a reasonable first fix while learning Rust alongside Tauri.
Tauri’s invoke() call silently does nothing. Confirm the command is listed in both generate_handler! in main.rs and allowed under the correct capability in default.json; a command missing from capabilities fails silently rather than throwing in some Tauri 2.x versions.
Electron app ships but antivirus software flags the installer. Unsigned Electron executables are flagged more often than signed ones; budget for a code signing certificate before any public release, regardless of which framework you choose.

Advanced Tips for Production Apps

Once the basic app works in both frameworks, a few less obvious practices separate a tutorial project from a production-ready one.

For Tauri, split your capabilities into multiple scoped files instead of one default.json, one for the main window and separate, tighter ones for any secondary windows like settings or about dialogs. This limits blast radius if one window’s frontend code is ever compromised. Also enable Tauri’s built-in CSP (Content Security Policy) configuration in tauri.conf.json rather than leaving it unset, since an unset CSP quietly disables a layer of protection the framework offers by default.

For Electron, adopt the sandbox: true flag on BrowserWindow in addition to contextIsolation, which runs the renderer process in an OS-level sandbox separate from the main process, meaningfully reducing what a compromised renderer can reach even if an attacker finds a bug in your preload script. Pair this with Electron’s official Electronegativity or similar static analysis tooling in CI to catch regressions in your security configuration before they ship.

For both frameworks, measure your real app’s bundle size and memory footprint on every release rather than trusting a one-time benchmark. A dependency update, a new feature pulling in a heavy library, or a new window can erode the lean numbers either framework starts with.

Complete Working Project Structure

At the end of this tutorial, your two project folders should look like this, ready to extend into something larger than a notes app.

notes-tauri/
  src/
    index.html
    main.js
  src-tauri/
    capabilities/default.json
    src/main.rs
    Cargo.toml
    tauri.conf.json
  package.json

notes-electron/
  main.js
  preload.js
  renderer.js
  index.html
  package.json

Both are complete, runnable desktop apps with local file persistence, a packaged installer, and an auto-update path wired in. From here, swapping the vanilla JavaScript frontend for React, Vue, or Svelte in either project is a drop-in change, since neither framework cares what frontend tooling renders inside its window.

Choosing a Frontend Framework Inside Tauri or Electron

This tutorial used plain JavaScript to keep the comparison clean, but almost nobody ships a production desktop app without a frontend framework layered on top. The good news is that the choice is mostly independent of whether you picked Tauri or Electron, since both are, at their core, a window that renders HTML and runs JavaScript, with a bridge to native code behind it.

React, Vue, and Svelte all work in either framework with essentially the same setup you would use for a regular web app, pointed at a Vite or webpack dev server during development and a static build output during packaging. Tauri’s official templates include React, Vue, Svelte, and vanilla options out of the box through the create-tauri-app wizard used in Step 3, which saves some initial wiring. Electron does not ship an equivalent official wizard, so most teams either hand-roll the Vite configuration or reach for a community boilerplate such as electron-vite to get a comparable starting point.

One subtlety worth testing early: Tauri’s smaller WebView footprint means your frontend bundle size actually matters more to the user-facing experience, since a large React bundle loading inside a lean 3 MB Tauri installer is a more noticeable mismatch than the same bundle loading inside an Electron app that was already carrying 85 MB of Chromium. If bundle size is the reason you picked Tauri in the first place, it is worth auditing your frontend framework’s own output size with a tool like source-map-explorer rather than assuming the backend savings alone will carry the whole app.

Which Major Apps Actually Ship on Each Framework

Electron’s track record includes some of the most widely used desktop software in the world: Visual Studio Code, Slack, Discord, and GitHub Desktop all run on it, which is a large part of why its ecosystem, tooling, and Stack Overflow answer coverage remain deeper than Tauri’s. Tauri’s production adoption is younger and more concentrated among newer, performance-conscious tools and smaller teams that prioritized install size and memory footprint from day one, a pattern that lines up with why its GitHub star count, while still substantial at an estimated 88,000 to 107,000 as of 2026, trails Electron’s roughly 107,000 to 121,000. A deeper technical breakdown of Tauri’s Rust-based architecture is available in a community-maintained Rust GUI ecosystem report, which tracks binary size and build characteristics across several Rust desktop frameworks.

Factor	Tauri 2.12	Electron 44
Backend language	Rust	Node.js
Rendering engine	OS-native WebView (WebView2, WebKit, WebKitGTK)	Bundled Chromium
Mobile targets	Android and iOS (Tauri 2.x)	None
Security default	Capability-based, deny by default	Configurable, opt-in isolation
Ecosystem maturity	Younger, growing fast	A decade of production use
Best fit	Lean new apps, teams comfortable with Rust	Teams needing rendering consistency, pure JS/TS teams

Frequently Asked Questions

Is Tauri actually faster than Electron, or just smaller?
Both. Public benchmarks run through 2026 put Tauri’s cold start around 380 milliseconds versus roughly 1,420 milliseconds for a comparable Electron app, in addition to the well-documented bundle size gap, though your exact numbers depend on your app’s own code and the host machine.

Do I need to know Rust to use Tauri?
For the frontend, no. For the backend commands shown in Step 6, yes, at least basic Rust syntax and an understanding of ownership. Many teams start with simple commands like the save/load example here and grow their Rust knowledge from there.

Can I migrate an existing Electron app to Tauri?
Yes, and the frontend HTML, CSS, and JavaScript typically carry over with minimal changes. The work is almost entirely in rewriting your main process logic (file access, native menus, IPC handlers) as Rust commands, which is a meaningful but bounded project for most apps.

Which framework has better cross-platform consistency?
Electron, because it ships the same Chromium build on every OS. Tauri depends on the WebView each operating system provides, which means small rendering differences can appear between Windows, macOS, and Linux that would not show up in an Electron app.

Is Tauri production ready in 2026?
Tauri 2.x, currently at 2.12.0, is production ready and used in shipped commercial apps. Tauri 3 is still an alpha release as of October 2026 and should not be used for anything you plan to release.

Does Tauri support mobile apps?
Yes. Tauri 2.x added Android and iOS targets built from the same Rust-based project structure used for desktop, something Electron does not offer natively.

Why does Electron still dominate if Tauri is smaller and faster?
Maturity and ecosystem depth. Electron has roughly a decade of production hardening behind apps like Visual Studio Code and Slack, more third-party libraries, more Stack Overflow coverage, and a team’s existing JavaScript skills transfer without needing to learn Rust.

What is the single biggest security difference between the two?
Tauri denies the frontend access to system resources by default and requires explicit capability grants per command. Electron grants access based on how you configure contextIsolation, nodeIntegration, and sandboxing, which means the security outcome depends heavily on the developer getting that configuration right.
