That's a fair statement! I would say we are similar to supabase in that we offer a relational backend. We are different in two ways:
1. Supabase runs on VMs, so only supports 2 free projects. We built the backend to be multi-tenant, so we can give you unlimited free projects.
2. Supabase doesn't support offline mode or optimistic updates. Instant gives you a sync engine which does.
