FreemiumFree TierAdded Sep 1, 2022

About

Convex is a backend platform that provides a reactive database, serverless functions, file storage, and scheduling — all with real-time sync built in. When data changes in Convex, connected clients update instantly without polling or manual WebSocket management. It uses a transactional database with TypeScript-native queries and mutations, making the backend feel like a natural extension of your frontend code. Ideal for collaborative apps, dashboards, and real-time features.

Origin Story

By James Cowling

Building It

What It Means

Shows that real-time should be the default for backends, not an add-on.

The Dream

Make every application real-time by default — no extra infrastructure, no polling, no complexity.
