PlanetScale vs Convex
Side-by-side database cost comparison — enter your storage and compute workload and see which provider is cheaper.
Database pricing is highly variable. Costs depend on query patterns, IOPS, connection pooling, and plan-specific limits this calculator cannot fully model. Treat these as order-of-magnitude estimates.

Per-seat pricing model: cost grows with team size, not data volume. Compare carefully against storage-based providers for larger teams.
Per-seat pricing: 1 developer × $25/mo = $25/mo base. DB I/O estimate (~0.05 GB/active hour) is a rough approximation — actual usage depends heavily on query patterns. Function call costs ($2/million) not included — too app-specific to model. Professional includes very high limits. Convex uses a document model, not Postgres. Direct SQL tools and ORMs are not compatible.

What PlanetScale excels at
- Millisecond-level billing: clusters are billed to the millisecond — no wasted spending on idle resources.
- HA clusters: 3-node HA available from $15/month — zero single-point-of-failure.
- Dedicated PgBouncer: connection pooling as a separate managed instance, not shared.
- Multiple cloud regions: 24+ regions across AWS and GCP.
- No vendor lock-in: standard Postgres — migrate in and out with pg_dump/pg_restore.
What Convex excels at
- Reactive queries: Convex functions subscribe to data — UI updates automatically when data changes without polling.
- TypeScript-native: fully typed queries, mutations, and actions — no SQL or ORM required.
- Built-in scheduling and cron: run background jobs and recurring tasks without a separate queue.
- Transactional mutations: all writes are fully ACID at the function level.
- Real-time by default: WebSocket subscriptions are a first-class primitive, not an add-on.
