Tauri
ELI5 — The Vibe Check
Tauri lets you build desktop apps using web technologies (HTML, CSS, JavaScript) but instead of bundling a whole Chromium browser like Electron, it uses the operating system's built-in web view. Result? Your app is 10-100x smaller. An Electron 'Hello World' is 150MB. A Tauri 'Hello World' is 2MB. It's desktop apps without the bloat.
Real Talk
Tauri is an open-source framework for building lightweight desktop applications using web frontends (any framework) with a Rust backend. It uses the platform's native webview (WebKit on macOS, WebView2 on Windows, WebKitGTK on Linux) instead of bundling Chromium, resulting in dramatically smaller binaries and lower memory usage. The Rust backend provides system-level access, security sandboxing, and native performance. Tauri 2.0 adds mobile support (iOS/Android).
