Tauri

Lightweight desktop apps with Rust backend and web frontend — smaller than Electron.

Overview

Tauri is a cross-platform application development framework that enables developers to build small, fast, and secure desktop and mobile applications from a single codebase. It supports Linux, macOS, Windows, Android, and iOS, allowing you to write your frontend in any JavaScript framework and application logic in Rust.

The framework prioritizes security and minimal app size by leveraging the operating system's native web renderer, resulting in apps as small as 600KB. Tauri is frontend-agnostic, meaning you can bring your existing web stack or start a new project without changing your technology choices.
