CockroachDB vs Supabase
Pricing
CockroachDB: 30-day trial with $400 credit, then from $0.092 per vCPU-hour
Supabase: Free tier, Pro from $25/mo
Description
CockroachDB: Distributed SQL database that survives outages, Postgres-compatible, with usage-based cloud pricing
Supabase: Postgres database with built-in auth, storage, and real-time (the open-source Firebase alternative)
Pros
- Postgres-compatible wire protocol: use your existing Postgres drivers and ORMs
- New cloud organizations get a 30-day trial with $400 of credit, no credit card needed for Standard
- Multi-region by design: your data survives zone and region failures automatically
- Full Postgres database, not a proprietary system: your data, your queries
- Auth, file storage, edge functions, and real-time included at no extra cost
- Free tier includes 500MB database and 1GB file storage
Cons
- No free tier for new customers: after the trial, Standard costs about $203/mo for 2 vCPUs and 100 GB
- Higher query latency than single-region Postgres (consensus overhead on every write)
- Overkill for most solo founder projects: distributed consistency adds complexity you rarely need
- Some Postgres features are missing or behave differently (limited extensions, partial full-text search functions)
- Some features (like edge functions) are still maturing compared to Firebase
- Free tier pauses inactive projects after 7 days
- Less hand-holding than Firebase: you need to know some SQL
Details
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.
Cloud pricing for new deployments from 15 September 2026 is pay-as-you-go. Every new organization gets a 30-day trial with $400 of credit. After that, clusters pause until you add a payment method and are deleted after a 30-day grace period. The Standard edition costs $0.092 per vCPU-hour, about $203 a month for 2 vCPUs and 100 GB, and Mission Critical costs $0.162 per vCPU-hour. Existing customers stay on their current plans. For most solo founders this is more database than you need, both in cost and in write latency. For simpler use cases, Neon or Supabase give you standard Postgres with free tiers.
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.
