Data tools that run on Browser. The Catch for each, not a winner list.
3 tools · the Catch, not a ranking
- NeonServerless Postgres that branches
Cold starts affect latency for scale-to-zero databases. The branching model has a learning curve. Regional availability is limited.
- PlanetScaleServerless MySQL with Vitess DNA
No foreign key constraints enforced by the database—application-level enforcement required. The Vitess heritage means some MySQL features work differently.
- ConvexReactive TypeScript backend with real-time sync
Not Postgres. Convex has its own data model and query language. Migration from existing databases requires rethinking your data layer. Chef (their AI feature) was deprecated. Vendor dependency is real.
