Best Backend-as-a-Service Platforms in 2026
Top BaaS platforms of 2026 ranked. Compare Supabase, Firebase, Appwrite, and more for authentication, databases, storage, and serverless functions.
How this list is built
We build Goodspeed, so we hold it to the same checks we apply to every tool here, and we call out where other tools lead. We implemented the same backend requirements on each platform: user auth, relational data, file storage, edge functions, and real-time subscriptions. We scored developer experience, pricing transparency, and vendor lock-in risk.
