Tauri is a production-grade framework for building cross-platform desktop and mobile applications using web frontends (HTML/JS/CSS) backed by a Rust core. The repository is a large monorepo containing the core library (`crates/tauri`), CLI tool (`crates/tauri-cli`), bundler (`crates/tauri-bundler`), runtime abstraction (`crates/tauri-runtime`), macros (`crates/tauri-macros`), code generation (`crates/tauri-codegen`), utilities (`crates/tauri-utils`), and platform-specific implementations for Windows, macOS, Linux, Android, and iOS. The architecture is modular: the core provides an application builder, plugin system, IPC (commands and events), window/webview management, tray icons, menus, state management, and a resource table. The CLI orchestrates development, building, bundling, and mobile workflows. The bundler produces platform-specific packages (MSI, NSIS, DMG, AppImage, deb, rpm, etc.). The framework emphasizes security through a capability-based ACL system, CSP injection, and an isolation pattern for IPC. It is actively maintained with frequent releases, extensive CI/CD, and a large ecosystem of plugins.
