Convex queries automatically update your app’s data in realtime. All user sessions see a consistent view of the backend state. This enables a smooth reactive user experience, with no refreshing or polling.
Everything, in its right place
Convex features are thoughfully designed to work together. Queries are full JavaScript functions that run transactionally on the database to provide strong data consistency. Automatic caching, file storage, search, and a scheduler come together to help you build sophisticated applications and workflows. Convex plays nice with the rest of your ecosystem too, with data snapshots and streaming import/export.
