A backend that re-renders your UI automatically when data changes.
Convex is a backend where your database functions double as your API, pushing updates to clients the moment data changes — no caches to invalidate.
Who it's for: Web app builders who want reactive data without a custom sync layer.
Functions that push updates to clients instantly.
Built-in blob storage with auth.
Cron and delayed jobs without extra infra.
Drop-in RAG, agents, and embedding helpers.
Convex removes the hardest part of app backends — keeping the client in sync. In 2026 its AI components make RAG apps trivial to stand up.
