I was thinking of sciter (5mb) and another similar crate that I can't remember the name for
My gtk-rs project is intended to replace a small, self contained win32 application. The application is 132KB. So although 5MB is small it's an oom larger than my benchmark.
However, my gtk-rs hello, world GUI application is 14.6MB in release mode and that does not include the GTK DLLs that are also needed. Yikes. That's crazy.
Perhaps 5MB is a reasonable price to pay for cross platform GUI. Not taking 7+ seconds to build a GUI hello, world would be nice as well.
(that's a Rust-specific framework, but the underlying webview library is just a C library)
