Tauri seems like a nice option. It's not as full-featured as Electron yet but their focus on security is great to see (last I saw they were getting the codebase professionally audited). The main reason I didn't go with it was just that doesn't seem to (yet?) suit my use case with zero-copy data transfer between Rust <-> Browser.

My hope is that by writing most of my backend in Rust, that it'd be easy-ish to switch to Tauri or other options if something changes down the road.
