Wrap up
How Local First is accidentally perfect for the AI age
May 27 12:00 - 12:15
When we set out to make local-first mainstream with Jazz, the two ideas that excited us the most were: a much simpler stack (no backend, nothing to integrate) — and: a much more declarative approach to writing apps (just a schema, plus UI).
Turns out that these make local-first perfectly suited for vibe-coding. In particular, we'll also show you how that's influenced our API design and how Jazz's unique local-first permissions might be the missing piece to make vibe-coded apps secure and production-ready with no extra work.
