webview
Tiny cross-platform webview library for C/C++. Uses WebKit (GTK/Cocoa) and Edge WebView2 (Windows).
"a thin wrapper over the system webview"
That is very complicated if you take into account also Linux, Windows, iOS, Android support and related utilities like tray icon, etc. There are other efforts, too, but they are also wrappers. Like this C/C++ implementation https://github.com/webview/webview that targets only desktop operating systems.

- Project mention: Microsoft is open sourcing Windows 11's UI framework | news.ycombinator.com | 2025-08-02
No, it implements its own functionality. As an example consider one of the most basic controls which is available pretty much everywhere (i.e. no need for polyfill), the push button: the source code[0] for QPushButton clearly implements the behavior itself, it does not rely on any native button.
Compare with wxWidgets' equivalent to QPushButton, wxButton, where there is a backend-specific header[1] and implementation[2] where 99% of the wxButton functionality is there (there is a `btncmn.cpp` under `common` that is shared across backends but that has very little code itself).
