Supabase

If you want a shortlist of established backend-as-a-service products people actually build with, start with Supabase and Firebase. The 2026 Stack Overflow Developer Survey reports substantial use of Supabase and Firebase database products, though its database categories are not a direct ranking of complete BaaS platforms. (survey.stackoverflow.co)

My practical pick: use Supabase unless you have a reason not to. Pick Firebase for a mobile/offline-first app, Amplify for an AWS-centered team, Appwrite when self-hosting matters, or Convex when realtime TypeScript development is the priority.

Roundups from 2026 agree on a short list. These are the platforms people most often use.

Top picks

1. Supabase is the best default for most new apps.

• It gives you Postgres, auth, storage, realtime, edge functions, and a clean escape hatch.
• It's open source under the Apache 2.0 licence.
• Pricing: from $25/mo on the Pro plan, per organization. The free plan pauses after 1 week of inactivity.

2. Firebase (Google) is the best for mobile apps.

• It's one of the most mature and widely adopted BaaS providers, with broad SDK support, strong realtime tooling, and deep Google ecosystem ties.
• It's a good fit when you need offline sync.
• The tradeoff is lock-in. Firebase is proprietary and runs only on Google's infrastructure.
• Pricing: Spark is free, and Blaze is usage-based with no monthly platform fee.

3. Appwrite is the best open-source, Firebase-style option.

• It's BSD 3-Clause licensed, with managed cloud or Docker self-hosting, and it unifies auth, database, storage, and messaging.
• It's a good pick if data ownership or self-hosting matters.

Other options for specific needs

• Convex is the best realtime TypeScript backend.
• AWS Amplify is the best AWS-native option. It makes sense if you're already deep in AWS.
• PocketBase is a whole backend in one binary, for small apps.
• Nhost is Postgres/Hasura-based and self-hostable.
• Back4app, Backendless, and Xano are low-code or no-code oriented. Xano and Backendless suit no-code teams.

Quick guide

As one source puts it, there is no single best backend as a service provider, only the best fit for your stack, stage, and growth plan.

If you're unsure, start with Supabase for web apps or Firebase for mobile. Pricing and free-tier limits change often, so check each vendor's pricing page before committing.

If you tell me what you're building, I can narrow it down.

The Backend as a Service (BaaS) market has evolved significantly. While Google’s Firebase pioneered the space, modern open-source and specialized platforms like Supabase and Convex have gained immense popularity by offering SQL databases, TypeScript integration, and self-hosting capabilities.
