Tauri is a framework for building high-performance desktop applications using a single web UI codebase. Unlike traditional web wrappers such as Electron, Tauri is built on Rust and leverages the operating system's native webview, resulting in smaller binaries and stronger security. We first evaluated Tauri several years ago; since then, it has expanded beyond desktop to support iOS and Android. The latest version introduces a more flexible permission and scope model, replaces the older permission list and features a hardened inter-process communication (IPC) layer that supports raw data transfer and improves performance. These updates are backed by an external security audit. Together with official distribution guidelines for major app stores, these improvements further strengthen Tauri's position in the cross-platform development space.
Tauri is an Electron alternative for building desktop applications using a combination of Rust tools and HTML, CSS, and JavaScript rendered in System's WebView. Unlike Electron which bundles Chromium, the applications built with Tauri leverage the underlying WebView, that is, WebKit on macOS, WebView2 on Windows and WebKitGTK on Linux. This approach has interesting trade-offs — on one hand you get small and fast application binaries; on the other hand, you need to verify compatibility quirks across WebViews of different systems.
