What it is
Convex is a backend platform with a document database, server functions, and live queries. The client updates when data changes, without you wiring a separate API and websocket. It is a different model from hosted Postgres.
Convex has a free developer plan and paid plans. Function calls and storage are the usual limits. Dollar amounts were not copied.
Why it ranks
- Live queries without a hand-rolled API
- Type-safe functions as the backend
- Free developer plan
Watch outs
- Not Postgres. Moving out later is a rewrite, not a connection-string swap
- You write functions in Convex's model
