I've build a self hosted convex/Firebase/Supabase alternative

This isn't another Firebase clone — it bakes authorization into the data model (you specify access when you create facts) and uses an RDF-style facts/triples API plus CRDT/OT for real-time merges. The demo hooks (useKeyValueAttributes) and OpenID Connect support make the client story feel thought-through, so this is worth a look if you need server‑sovereign, multi-app data sharing rather than a client-first offline story.
