## The Hook

Convex is the reactive TypeScript backend that syncs in real-time.

## What's Good

Write backend logic in TypeScript, get real-time sync to the client automatically. No REST endpoints to define, no WebSocket plumbing to maintain. Queries are reactive—data changes, UI updates. The developer experience is genuinely different from traditional backends. Strong typing end-to-end.

## The Catch

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.

## Verdict

Reactive backend that feels like the future. Not Postgres.
