Is Supabase really a Firebase alternative?

Yes. Supabase provides the same core BaaS features — authentication, database, storage, real-time subscriptions, and edge functions — built on PostgreSQL instead of proprietary databases. The Postgres foundation means you can query your data with full SQL and use the entire Postgres ecosystem.

Is Firebase still the best BaaS?

Firebase is the most established BaaS and has the deepest Google Cloud integration. It is the best choice for teams building mobile-first apps that benefit from Firestore's offline-first sync and Google's infrastructure. For teams that prefer relational databases and open-source tooling, Supabase is the stronger choice.

Can I self-host Supabase?

Yes. Supabase is open source and can be self-hosted with Docker. This is a genuine advantage over Firebase, which is cloud-only. Self-hosting gives you full control over data residency, costs, and infrastructure.

Is Appwrite ready for production?

Yes. Appwrite has matured significantly and supports authentication, databases, storage, functions, and messaging. Its self-hosted-first design makes it popular for teams that want BaaS features without cloud dependency. The community is smaller than Supabase's or Firebase's but growing.
