Convex¶
What it is¶
Convex (convex.dev) is a "complete backend solution for app developers" centred on a reactive database primitive — client-subscribed queries that auto-update on write, akin to Firebase Realtime Database but with strongly-typed TypeScript functions and transactional semantics.
Why it shows up on this wiki¶
Convex is named as the launch-window production customer for PlanetScale for Postgres (2025-07-01 announcement): "Convex, the complete backend solution for app developers, is migrating their reactive database infrastructure to PlanetScale for Postgres." Migration writeup at pscale.link/convex (not summarised in the PlanetScale launch post).
Seen in¶
- — launch-customer reference; PlanetScale links the Convex migration writeup without architectural summary.
Caveats¶
Minimal-viable page. Convex's internals (reactive-query engine, WAL / changefeed architecture, Postgres integration details) are not covered by any source on the wiki as of this ingest.
