CockroachDB vs Supabase

CockroachDB is a distributed SQL database that speaks the Postgres wire protocol. Your existing Postgres drivers, ORMs, and queries work without changes. The key selling point is resilience — data is automatically replicated across nodes, so a zone going down does not take your database offline. The Serverless free tier gives you 10 GiB of storage and 50 million request units, which covers a moderate production workload.

For most solo founders, CockroachDB is more database than you need. The distributed architecture adds write latency (each write requires consensus across nodes), and you are paying that cost even if your app runs in a single region. Where it makes sense is if you are building something that genuinely needs multi-region availability or you want to avoid ever dealing with database failovers. For simpler use cases, Neon or Supabase give you standard Postgres with less overhead.

Supabase gives you a real Postgres database with the convenience of Firebase. Set up a project, and you immediately get a database, auth system, file storage, edge functions, and real-time subscriptions. No piecing together separate services.

The free tier is enough to build and test a real product. The Pro tier at $25/month gives you a production-ready setup. The key advantage over Firebase: it is Postgres under the hood. Your queries are standard SQL, and you can migrate your data to any Postgres host if you ever want to leave. That data portability is worth a lot for a solo founder building something long-term.
