Electrobun lets you open/manipulate/close webview windows and communicate with them using typed rpc. It also handles building, code signing, and notarization.
And because I'm using Bun, running an HMR + React + Tailwind server is just one command (`bun ./index.html`) or like 5 lines of code. Pass --console and the webview's console.log()s get streamed to your Terminal too.
There's tons of other things Electrobun does that I haven't even mentioned, because I haven't interacted much with them yet. E.g. I know that it lets you show platform-native notifications, prompts/popups, etc.
There also is a very impressive updating mechanism that relies on a bsdiff implementation written in Zig. You just ship the deltas, so updates to very large apps are just a few KBs most of the time.
It's genuinely a very productive stack and impressive piece of tech.
[1] Not affiliated - I just like the project.
[2]: The API and implementation was clear, so I'll cautiously say this is not a case of "rewrites are always faster". In fact, the Tauri version was a rewrite too :)
