ความเห็นบรรณาธิการ

I use Supabase for most of my projects — the Postgres foundation means I can always fall back to raw SQL when the abstraction layer isn't enough. But I recently built a collaborative whiteboard on Convex and the DX was genuinely magical. Data just... updates. Everywhere. No subscriptions, no state management headaches. If real-time is your core feature, try Convex. For everything else, Supabase is the safe pick.
