Tauri vs Electron: choosing a desktop app framework

Once a team decides a desktop app should be built with web technology rather than a native toolkit, the next decision is which runtime carries that web UI to the desktop. Electron and Tauri answer that question in opposite ways. This guide was updated in November 2026 for Electron 45 and Tauri 2.12, with sourced size and memory figures. If a full custom browser is also an option, see our guide to Chromium.

What is the difference between Electron and Tauri?

Electron ships its own copy of Chromium and Node.js inside every app, so the same engine runs everywhere. Tauri ships no browser engine: it uses the web view the operating system already has, with a Rust backend. That one choice drives the size, memory, security and consistency differences.

Tauri’s web view reference lists the engines: WebView2 (based on Microsoft Edge, so Chromium) on Windows, WKWebView on macOS and iOS, WebKitGTK on Linux, and the system Android WebView on Android.

How do Electron and Tauri compare side by side?

Electron gives you one Chromium version on every platform, a JavaScript backend and a large ecosystem, at the cost of bigger installers. Tauri gives you much smaller apps, a Rust backend and iOS and Android targets, but three different rendering engines across desktop platforms.

Versions come from Electron’s release schedule (Electron 45.0.0, October 20, 2026) and Tauri’s GitHub releases, where the latest Tauri 2 release when we checked was 2.12.5. Tauri 3 is in alpha; we would build production apps on 2.x for now. Both need code signing, and macOS builds need notarization (Apple’s malware check).

Is Tauri smaller and lighter than Electron?

Smaller, yes: Tauri’s docs say a minimal app can be under 600 KB, while Electron carries Chromium and Node.js. Lighter on memory, usually: one public benchmark (six windows, one run on a MacBook Pro) measured about 172 MB for Tauri against 409 MB for Electron. Measure your own app.

• Size. Tauri’s introduction says a minimal Tauri app can be less than 600 KB, because it ships only your code and assets. Linux AppImages are the exception: Tauri’s AppImage guide warns the file grows from the 2–6 MB range to 70 MB or more, because it bundles its dependencies.
• One public benchmark. Hopp’s July 2025 comparison built the same small app in both on a MacBook Pro. It measured an app of about 8.6 MB for Tauri against 244 MB for Electron, and about 172 MB of memory against 409 MB with six windows open. Startup time was close in both. The author notes it was a single run.
• Measure your own app. The system web view runs its own processes too, so memory use depends on the platform and on what your app does. Size is the reliable win; check memory on the hardware your users have.

How do security updates work in Electron and Tauri?

With Electron you ship the engine, so you ship its security fixes: a new major comes every 8 weeks and only the latest three get fixes. With Tauri the operating system updates the web view, except on Linux, where it depends on the distribution’s WebKitGTK packages.

• Electron: Electron’s release timelines say a new major version ships every 8 weeks and only the latest three stable majors are supported. In the current schedule, each major reaches end of life about six months after release (Electron 45’s is planned for April 27, 2027). Your app is only as current as the last Electron update you shipped.
• Tauri: on Windows, WebView2 updates itself; on macOS, WKWebView updates with the OS, and unsupported macOS versions stop getting WebKit updates; on Linux, the WebKitGTK version depends on the distribution. Tauri’s updater plugin requires signed updates and says this cannot be disabled.
• Defaults: Electron’s security checklist notes context isolation has been the default since Electron 12 and renderer sandboxing since Electron 20. A small preload script and checks on every message between the page and the main process (IPC) are still up to you. Tauri exposes only the Rust commands and permissions you declare.

When should you choose Electron?

Choose Electron when the app must render the same on Windows, macOS and Linux, when your team and backend are JavaScript and Node.js, or when you are extending an Electron app that already ships. Bigger installers and more memory are the price.

• The same engine version has to run everywhere. If a rendering or behavior difference between Windows, macOS and Linux is unacceptable, bundling one known Chromium build removes a whole category of platform-specific bugs.
• The backend depends on Node.js. Existing Node modules, a team fluent in JavaScript on both ends, or heavy reuse of a Node-based backend all favor Electron.
• You are extending an existing Electron product. In our experience, rewriting a mature Electron app’s backend in Rust to save on installer size is rarely worth it once the app already works and is shipping.

When should you choose Tauri?

Choose Tauri when installer size or memory is a hard limit, when you want native access locked down by default, when your team can write some Rust, or when iOS and Android are on the roadmap. Budget extra testing for the different web views.

• Installer size and memory are hard limits. Users with limited bandwidth or storage, or many app instances at once, make Tauri’s lighter footprint a direct, measurable win.
• You want native access locked down by default. A compromised frontend can reach only the commands and permissions you listed.
• The team can take on Rust, or already has it. Tauri’s backend is Rust-first.
• Mobile is on the roadmap. Tauri 2 can target iOS and Android from the same project.

What problems do teams hit with Tauri?

Rendering differences. A UI that looks right in WebView2 during development on Windows can render CSS, fonts or a specific web API differently in WebKitGTK on Linux. Budget cross-platform testing time for a Tauri app, as you would for a website that has to work across browser engines, because that is what it is.

Can you migrate an Electron app to Tauri?

Yes, but treat it as a backend rewrite with a reusable frontend. A React, Vue or Svelte UI usually carries over with modest changes. The Node.js main-process code has no direct equivalent and must be rebuilt as Rust commands and plugins.

A frontend built with a standard framework usually carries over, since both host a web page. The backend does not: Node.js main-process code has to be rebuilt against Tauri’s command and plugin system. When we take on an Electron to Tauri move, we start by assessing the Node.js dependencies and the web view risks, then move native code into a small Rust core in stages. Our Tauri desktop app development service covers that work.
