Why the models rank Firebase — on best backend-as-a-service for startups
“Best-in-class mobile SDKs, offline sync, realtime listeners, mature auth, functions, storage, push notifications, crash reporting, analytics, and proven managed scaling; SQL Connect now also covers relational applications. It would rank first for a mobile-first or offline-first consumer startup.”
Why the models rank Supabase — on best backend-as-a-service for startups
“Best default for a web or full-stack startup: full PostgreSQL, row-level security, generated APIs, mature auth, storage, realtime, edge functions, strong local tooling, managed hosting, and a credible self-hosting path at startup-friendly cost. It is a near-tie with Firebase; this rank assumes relational data and portability matter more than offline-first mobile support.”
