Building with Convex
With Convex you write queries, mutations, and actions as TypeScript functions that run on Convex's servers. Queries are reactive: when the data they read changes, subscribed clients receive the new result automatically.
What Convex Is Good At
- Mutations run as transactions, so concurrent writes don't leave data half-updated.
- Schemas and argument validators are written in TypeScript, and client types are generated from them.
- Scheduled functions and cron jobs handle background work.
- Reusable components cover features such as rate limiting and workflows.
Common Use Cases for Convex
- Collaborative and multiplayer apps
- Live dashboards and leaderboards
- AI apps that run long tasks in the background

Frequently Asked Questions About Convex
How is Convex different from a database plus an API server?
You don't run a separate API layer or websocket server. Client code calls your Convex functions directly, and query results stay up to date as the data changes.
Can Convex handle production workloads?
Convex is a hosted service with paid plans for production teams. Check its documented limits and pricing against your expected load before committing.
