WebUI is a lightweight, open-source library that lets you build cross-platform desktop applications using web technologies (HTML, CSS, and JavaScript). Unlike frameworks that bundle a built-in browser, WebUI uses the user’s existing installed browser as the app’s graphical interface (GUI). WebUI was originally created by Hassan Draga and is now maintained by the open-source community. It supports backend languages such as C/C++, Zig, Python, Go, Bun, Deno, and more through wrappers.
A WebView option was added recently as an additional alternative.
