Tauri

Tauri is an open-source, Apache-2.0 / MIT-licensed framework for building cross-platform desktop and mobile applications that pair any JavaScript frontend with a compiled Rust backend. We rate it 88/100 — the strongest Electron alternative in 2026 for teams that want sub-megabyte installers, native performance, and a single codebase that ships to Windows, macOS, Linux, iOS, and Android.

What is Tauri?

Tauri is a framework built by the Tauri Programme within the Dutch non-profit Commons Conservancy, maintained by a working group that includes co-founder Daniel Thompson-Yvetot and the team at CrabNebula. The first 1.0 release shipped in June 2022; the stable Tauri 2.0 release landed on October 2, 2024, and the project has since grown to 106,000+ GitHub stars, with tauri-cli v2.10.1 released on March 4, 2026.

The fundamental idea: instead of bundling an entire Chromium runtime with every app like Electron does, Tauri reuses the operating system's native webview (WebKit on macOS/iOS, WebView2 on Windows, WebKitGTK on Linux, Android System WebView on Android) and communicates with a Rust binary via a secure IPC bridge. The result is dramatically smaller, faster, and more memory-efficient apps — and a security model that is locked-down by default.

Key Features of Tauri

• Tiny binaries: A minimal Tauri app compiles down to around 600 KB, versus 80–200 MB for a comparable Electron app — roughly a 96% reduction in install size.
• Low memory footprint: A typical Tauri window idles at around 50 MB of RAM; the equivalent Electron window is closer to 120 MB, because Tauri reuses the OS webview instead of shipping Chromium.
• Frontend-agnostic: Works with React, Svelte, Vue, SolidJS, Angular, or plain HTML — the Rust side does not care what framework produced the HTML.
• True mobile support (Tauri 2): The same project now builds to iOS and Android alongside Windows, macOS, and Linux, with a mobile plugin system that exposes native Swift and Kotlin APIs.
• Capability-based security: Tauri 2 replaced the old allowlist with an explicit capability permissions model — every Rust command the frontend can call must be granted, per-window, per-remote-origin.
• Sidecars and plugins: Ship extra binaries (e.g. Python, ffmpeg) alongside your app, and use first-party plugins for notifications, filesystem, HTTP, SQL, updater, deep linking, NFC, biometrics, and more.
• Auto-updater and code-signing: Built-in signed updates, with official guides for shipping to the Apple App Store, Google Play, Microsoft Store, Flathub, Snapcraft, the AUR, and CrabNebula Cloud.

What Users Say About Tauri

Developer sentiment on Reddit (r/rust, r/webdev) and Hacker News is unusually positive for a young framework. The most upvoted HN thread praises the startup time — Tauri apps launch in under 500 ms on a mid-range laptop, versus 1–2 seconds for the Electron equivalent — and the install size difference, which saves roughly $8,700–$13,775/year in distribution bandwidth at a scale of 100,000 users according to a widely-cited 2026 benchmark from pkgpulse.

The recurring complaint is ecosystem maturity. Electron has a decade-old catalogue of npm packages for every imaginable desktop concern; Tauri plugins still need to be ported or rewritten, and native-dependency crates sometimes require Rust knowledge to debug. A second common grumble is WebView inconsistency: because you are rendering on the OS webview, a layout bug in WebKitGTK on Ubuntu 22.04 does not automatically exist on Windows WebView2 — you test everywhere or you accept that reality.

The Aptabase engineering team publicly switched from Electron to Tauri and credited it for a 20× reduction in installer size and materially lower crash rates, which is representative of the honest tradeoff: Tauri is a better product once you clear the Rust bar.

Tauri Pricing

Tauri is free and open source under a dual MIT / Apache-2.0 license. There is no paid tier, no seat pricing, and no telemetry. Revenue to the project comes through the Open Collective and GitHub Sponsors — notable sponsors include 1Password, Sourcegraph, Sentry, and RxDB.

Plan	Price	What You Get
Open source	$0	Full framework, all plugins, CLI, mobile targets, unlimited apps and distribution — no restrictions
CrabNebula Cloud (optional)	Paid tiers	Managed auto-update channels and release hosting from the team behind Tauri — entirely optional

Who Should Use Tauri?

Best for: Indie developers and product teams who ship a desktop or cross-platform app to end users and care about install size, startup time, or RAM usage — launchers, note-taking apps, chat clients, developer tools, local-first utilities, finance apps, and privacy-sensitive software. Also a strong pick for any team that already uses Rust on the backend.

Not ideal for: Teams with zero Rust experience on a tight deadline, apps that rely on deep Chromium-only browser APIs (e.g. obscure experimental Web APIs only Blink implements), or internal enterprise tools where install size is irrelevant and Electron's huge npm ecosystem saves weeks of work.

Pros and Cons

Pros:

• Roughly 96% smaller installers than Electron for equivalent functionality
• Sub-500 ms startup versus 1–2 s for Electron
• Secure by default — capability-based permissions, no full Node access from the frontend
• One codebase now builds to five platforms including iOS and Android
• Completely free, no future commercial licensing trap (dual MIT / Apache-2.0)

Cons:

• You will write Rust — plan on a learning curve if your team is pure TypeScript
• WebView fragmentation: same HTML/CSS can render subtly differently on WebKit, WebView2, and WebKitGTK
• Smaller plugin ecosystem than Electron — some native integrations still need to be written by hand
• Windows users without the WebView2 runtime installed need the installer to bootstrap it (Tauri handles this, but it is an extra step)

Alternatives to Tauri

Electron — the incumbent, bundles Chromium and Node. Much larger ecosystem, much larger apps. Wails — similar idea but with a Go backend instead of Rust. Neutralino — lighter still, but far less mature. Flutter Desktop — single codebase too, but renders its own UI rather than using a webview and is the right choice if you do not want HTML/CSS at all. For most teams in 2026, the real choice is Tauri vs. Electron, and Tauri wins on every metric except ecosystem breadth.

Verdict: Is Tauri Worth It?

Yes, for the right team. If you are shipping a consumer or prosumer desktop app in 2026 and you have even one engineer comfortable with Rust — or willing to learn — Tauri will give you a faster, smaller, more secure product than Electron with almost no ceiling on what you can build. The gap between "Electron is easier because of JavaScript" and "Tauri is better because of everything else" keeps narrowing with each release; the JavaScript API in Tauri 2 already covers roughly 90% of what most apps need before you have to touch Rust at all. At 88/100, Tauri is the desktop framework to build on in 2026 unless you have a very specific reason not to.

Frequently Asked Questions

Is Tauri free?

Yes. Tauri is completely free and open source under a dual MIT / Apache-2.0 license. There is no paid tier, no seat limit, and no commercial license required for shipping paid products built with it.

What platforms does Tauri support?

Tauri 2 targets Windows, macOS, Linux, iOS, and Android from a single codebase. It reuses each OS's native webview to render the frontend.

How does Tauri compare to Electron?

Tauri apps are typically 96% smaller on disk (around 600 KB vs. 80–200 MB for Electron), start in under 500 ms versus 1–2 s, and use roughly 50 MB of RAM versus 120 MB+. The tradeoff: Electron has a much larger npm ecosystem, and Tauri requires Rust on the backend.

Is Tauri open source?

Yes. The source is on GitHub at github.com/tauri-apps/tauri with 106,000+ stars, dual-licensed MIT / Apache-2.0.

Do I need to know Rust to use Tauri?

For a basic app, no — the JavaScript API in Tauri 2 handles filesystem, notifications, HTTP, dialogs, updates, and more without writing any Rust. You only need Rust when you want to add custom native commands or integrate a native library not already wrapped by a plugin.
