This is awesome! I built a similar tool as an experiment while at Recurse: https://github.com/zephraph/webview. Didn’t really do any heavy lifting though, just reused some of Tauri’s crates. Does Bun run on the same process as the GUI binding? OSX steals the main thread when rendering a native window which made me lean towards separating the processes. Still wonder if there’s a better way.

I’m using bun for the main process. Bun runs a zig binary which can call objc/c methods. So the “main native application thread” is technically the zig process.

Then there’s all kinds of fancy rpc between bun and zig and between bun and browser contexts.
