yJS has the webrtc adapter and appears to still win out in the edit benchmarks. I’ve used yJS in two projects: once just for presence chat and syncing menus for a coaching site and once in a overlay graphics app for a livestream

Biggest problem with yJS for me has been the ergonomics when I use it with React. There’s a third party project called synced store that I used for the stream overlay but it has some strange behavior.

With first party support with React in automerge I think it’s worth a shot for my rewrite
