Summary of Convex

Convex | The reactive database for app developers Convex

Convex is an open-source, reactive database designed specifically for modern web and mobile app developers. It combines database, backend logic, and real-time sync capabilities into one TypeScript-first platform, eliminating the need for separate state managers, cache invalidation strategies, or manual WebSocket management.


  • Provides automatic real-time synchronization between your frontend UI, backend functions, and database state
  • Enables you to write backend code—queries, mutations, cron jobs, AI-driven workflows, and auth—directly in TypeScript
  • Ships with a growing ecosystem of pre-built components for common backend needs, installable via npm
  • Offers built-in authentication, scheduling, and serverless function execution without infrastructure overhead

  1. Everything as Code
    You define your schema, queries, and mutations in TypeScript files alongside your application code. This delivers full type safety and autocompletion throughout your stack.
  2. Generated Client Hooks
    Convex’s build process generates client-side hooks (e.g., React hooks) from your server code. When you call a query or subscribe to a dataset, the UI automatically reflects any database changes.
  3. Serverless Execution Engine
    Your backend functions run on Convex’s serverless infrastructure. Every mutation or cron job is executed in a secure, scalable environment without provisioning servers.
  4. Reactive Change Propagation
    Under the hood, Convex tracks dependencies between data and queries. When data changes, it pushes updates to subscribed clients in real time, ensuring your UI is always in sync without manual WebSocket wiring.

Convex integrates smoothly with popular frameworks and languages—React, Next.js, React Native, Vue, Svelte, Python, Rust, and more—so you can adopt it incrementally. Its TypeScript-first design also plays nicely with AI-based code generation tools, letting you scaffold new backend functions with minimal manual typing. This holistic approach future-proofs your stack by keeping your data model, business logic, and UI in lockstep.
