tauri-apps/wry

WRY is a cross-platform library written in Rust that lets developers embed a web browser view inside a desktop application window. It is a core building block of Tauri, a popular framework for building desktop apps using web technologies. If you have used an app built with Tauri, WRY is the piece responsible for rendering the HTML and JavaScript that makes up the user interface. The library works by using whatever web engine the operating system already provides, rather than bundling its own browser. On macOS it uses WebKit, which is the same engine that powers Safari. On Windows it uses WebView2, which comes from Microsoft Edge. On Linux it uses WebKitGTK. This approach keeps the distributed app size small, since no browser engine needs to be shipped alongside the app. WRY supports Windows 7 and later, macOS, Linux, Android, and iOS. Embedding a webview into a window takes just a few lines of Rust code: you point it at a URL or give it raw HTML, attach it to an existing window, and it handles the rendering. The library also supports positioning webviews as child panels inside a larger window, which lets you mix native controls with web content on screen at the same time. There are some platform-specific setup steps to be aware of. On Linux you need to install system packages such as WebKitGTK before the library will work. On Android you need to configure a few environment variables and set up a specific activity in your project. The README includes copy-paste install commands for major Linux distributions including Debian, Ubuntu, Fedora, and Arch Linux. The project is maintained by the Tauri team and is licensed under both MIT and Apache 2.0. Most developers will encounter WRY indirectly through Tauri rather than using it directly, but it is designed to be usable as a standalone library for anyone building their own desktop app framework in Rust.
