I had the same problem, regarding localStorage synchronization. For that I made htmlsync.io, but only really worth it for people who have many local apps like that and really need the localStorage sync.
Thanks! Pretty much, yes. Also if you are a dev and just don't want to spin up a server for every simple app you vibe code, you could find this useful.
To be honest, I wanted this for myself and felt guilty not making something more serious out of it since I liked the idea.
