Tauri is an open-source framework for building apps for Linux, macOS, Windows, Android, and iOS from one codebase. You write the interface with any web frontend and the app logic in Rust, with Swift and Kotlin for deeper native integration. Tauri doesn't bundle a browser. It uses each OS's native webview, so a minimal app can be under 600KB. It suits web developers who want lighter, more secure apps than frameworks that ship their own browser engine.

• Frontend Independent: Use any framework that compiles to HTML, JavaScript, and CSS. You can bring your existing web stack, and the docs include setup guides for popular frameworks.
• One Codebase, Five Platforms: Target Linux, macOS, Windows, Android, and iOS from a single project. You don't need a separate app for each platform.
• Tiny App Size: Tauri uses the operating system's native webview instead of bundling a browser engine. A minimal app can be under 600KB.
• Rust-Powered Core: Your application logic runs in Rust, which adds memory, thread, and type safety. Your frontend calls Rust functions through the invoke function.
• Layered Security Model: Capabilities, permissions, and scopes control exactly which system commands your webview can reach. CSP and the Isolation Pattern add further protection, and major and minor releases go through a security audit.
• Official Plugin Library: About 30 maintained plugins cover common needs such as Updater, Autostart, Store, SQL, Notifications, Deep Linking, and Stronghold. Community plugins add more.
• Built-In Bundling and Distribution: Create .app, .dmg, .deb, .rpm, AppImage, .exe (NSIS), and .msi packages. Guides cover the App Store, Google Play, Microsoft Store, Flathub, Snapcraft, AUR, and code signing on every platform.
• Quick Project Setup: Start a project with create-tauri-app through npm, Yarn, pnpm, Deno, Bun, Cargo, or shell scripts. A GitHub Action and a VS Code extension support your workflow.

• Much Smaller Apps: You use the system webview instead of shipping Chromium, so your installers and memory use are a fraction of what bundled-browser apps need.
• Desktop and Mobile in One Project: Version 2 added iOS and Android, so you can reach five platforms with one codebase. Few web-tech frameworks offer this.
• Secure by Default: The frontend can only reach system features that you grant explicitly. Regular security audits add confidence for production apps.
• Keep Your Web Skills: You don't have to learn a new UI toolkit. Your existing React, Vue, Svelte, or plain HTML frontend works.
• Free and Open Source: Tauri is released under the MIT and Apache-2.0 licenses with no license fees. Sponsors such as CrabNebula, 1Password, and Sentry support the project.

• Rust Required for Backend Logic: App logic and native commands are written in Rust. That fits Rust-savvy teams, but JavaScript-only teams have more to learn than with Node.js-based alternatives.
• Rendering Varies by Platform: Tauri uses each OS's own webview, such as WebKit on macOS and WebView2 on Windows. You need to test on each target, while bundled-Chromium frameworks render the same everywhere.
• Smaller Ecosystem Than Electron: Tauri has an official plugin set and a growing community, but Electron has more than a decade of packages and examples. You may need to build some integrations yourself.
• Self-Updater Is Desktop Only: The built-in updater covers desktop apps. Mobile apps update through the app stores.

• Lightweight Desktop Utilities: Build a menu-bar tool, system tray app, or productivity utility that downloads quickly and uses little memory. Users get a native-feeling app without a large download.
• Migrating from Electron: Move an existing web-based desktop app to Tauri and keep your frontend code. Teams that have migrated report much smaller bundles and faster startup.
• Cross-Platform Desktop and Mobile Apps: Build applications for Windows, macOS, Linux, iOS, and Android from a shared project. Reuse your frontend and much of your application logic instead of maintaining five completely separate applications.
• Privacy-Focused and Local-First Apps: Build apps that keep data on the user's device, such as local AI tools, note apps, or password managers. The permission system and Rust backend limit what the UI can reach.
• Internal Business Tools: Turn an internal web dashboard into a signed, installable desktop app with auto-updates. You can distribute it through installers like MSI or DMG, or through app stores.
• Developer Tools and Clients: Create API clients, database viewers, or debugging proxies that need fast native access to system resources through Rust.
