Supabase
Supabase flips Firebase’s default by making Postgres and SQL the center of the stack, which is a big win for teams that want relational modeling, joins, and predictable querying. Instead of adapting everything to a proprietary NoSQL query model, it lets apps lean on familiar database primitives like constraints, migrations, and extensions while still feeling like a modern backend platform.
A major differentiator is Row Level Security, where authorization rules live alongside the data and can be enforced consistently no matter which client or service hits the database. That approach can reduce the amount of custom middleware and edge-case security logic that often accumulates in app code when scaling beyond a simple prototype.
Supabase also stands out for its “backend kit” completeness: database, auth, storage, realtime, edge functions, and a dashboard that helps teams ship quickly without assembling a dozen services. And because it’s built around Postgres and an open-source posture, it offers a clearer exit path than many managed BaaS options—useful if requirements change or a team later chooses to self-host or move providers.
The main trade-offs are that SQL and RLS can add learning curve for Firebase-native builders, and some workloads may require care around function latency and usage-based costs at scale.
