NanUI is an open-source .NET framework for building Windows desktop (WinForm) applications whose user interfaces are written in HTML5, CSS3, and JavaScript. It is built on Xilium.CefGlue, a .NET wrapper around the Chromium Embedded Framework (CEF), letting developers combine web-technology UIs with C# business logic.
Use cases
- build a Windows desktop app with an HTML/CSS/JavaScript UI
- create a modern-looking WinForm application with web technologies
- embed a Chromium browser view inside a .NET desktop application
- mix C# backend logic with a web-based frontend in a native window
- make a borderless or custom-chrome desktop app using HTML
- support Windows 7 SP1+ clients with a .NET desktop UI
When to choose
- you want web-technology UIs in a .NET WinForm app and need Windows 7 SP1 support
- you need a full Chromium engine (CEF) inside your desktop application
- your team knows HTML/CSS/JavaScript better than WinForms/WPF UI design
- you want custom window chrome or offscreen rendering features like DirectComposition
When to avoid
- you need cross-platform support - NanUI is Windows-only
- you want a lightweight package - CEF-based apps are large (~125MB+ compressed); consider WinFormedge/WebView2 instead
- you target only Windows 10/11 and prefer the system-provided WebView2 runtime
- you are building a web app rather than a native desktop application
