Tauri
Build cross-platform desktop applications using web technologies (HTML, CSS, JS/TypeScript) with a Rust backend. Tauri uses the OS's native WebView instead of bundling Chromium, resulting in app sizes of 2-10MB vs. Electron's 50-150MB. The Rust backend provides system access (file system, notifications, shell, native menus) via a typed IPC bridge. Tauri 2.0 added mobile support (iOS, Android) alongside desktop (macOS, Windows, Linux).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Capability system explicitly controls frontend access to system APIs — secure by default. Rust memory safety. Process isolation between WebView and Rust backend. MIT/Apache 2.0 licensed.
⚡ Reliability
Best When
You want a small, secure desktop app using web frontend technologies and can write some Rust for system integration — as an Electron alternative with better security and 10x smaller binaries.
Avoid When
Your team has no Rust experience, you need consistent rendering across all platforms, or your app is web-only.
Use Cases
- • Build desktop applications using React, Vue, or Svelte frontends with Rust backend for system access — 10x smaller than equivalent Electron apps
- • Create agent desktop clients that need file system access, system notifications, and native OS integration using Tauri's Rust command system
- • Distribute cross-platform desktop tools as small executables without requiring users to install Node.js or a runtime
- • Build AI desktop assistants or coding tools that integrate with the local file system and system clipboard using Tauri's plugin system
- • Package existing web applications as desktop apps with auto-updater, native menus, and system tray support using Tauri
Not For
- • Web-only applications — Tauri is for distributable desktop apps; deploy web apps to Vercel/Netlify
- • Teams without any Rust knowledge — the Tauri backend requires Rust for custom system commands; JS-only developers may hit walls
- • Applications requiring consistent cross-platform rendering — native WebViews vary by OS (WebKit on macOS/Linux, WebView2 on Windows); CSS may render differently
Interface
Authentication
Desktop app framework — auth is implemented in the application layer. Tauri's capability system controls which APIs are available to the frontend WebView.
Pricing
Tauri is MIT/Apache 2.0 dual-licensed open source. Free for personal and commercial use. Supported by the Tauri Programme Foundation non-profit.

Known Gotchas
- ⚠ Tauri requires Rust toolchain, system WebView libraries, and platform-specific build tools — setup is more complex than Electron; use the create-tauri-app scaffolding tool for correct dependencies
- ⚠ Tauri 2.x changed the capability system — permission scopes now explicitly declare which Tauri APIs the frontend can access; missing capability grants cause cryptic 'not allowed' errors
- ⚠ Native WebView rendering differs by OS — macOS uses WebKit, Windows uses Edge WebView2, Linux uses WebKitGTK; test on all target platforms as CSS/JS may behave differently
- ⚠ Tauri IPC commands must be registered in Rust with #[tauri::command] and added to the builder — calling unregistered commands from the frontend fails silently with a timeout error
- ⚠ App signing and notarization for macOS distribution requires an Apple Developer account ($99/year) — without signing, macOS Gatekeeper blocks app launch
- ⚠ Tauri's updater requires a signing key and update server — setting up the auto-update pipeline has significant infrastructure requirements beyond the app itself
