Product Overview
What is Convex?
Convex is a modern backend-as-a-service designed for app developers who want to build dynamic, real-time applications with minimal infrastructure overhead. It provides a reactive document-relational database, seamless real-time synchronization between frontend and backend, and a unified environment to write backend logic entirely in TypeScript. Convex eliminates the need for manual state management, cache invalidation, or WebSocket handling by automatically syncing data and code changes. Its architecture ensures strong transactional guarantees and consistent app state, making it suitable for scaling production apps with confidence.
Key Features
Reactive Document-Relational Database
Stores JSON-like documents with relational capabilities and automatically reruns queries when dependent data changes, ensuring real-time updates.
TypeScript-First Backend Functions
Backend logic, including queries, mutations, and actions, is written in TypeScript with full type safety and IDE support, simplifying development.
Automatic Real-Time Sync
Client libraries use WebSockets to keep frontend UI instantly updated with backend and database changes without manual intervention.
Transactional Mutations
All database mutations run as atomic transactions, guaranteeing consistent state and preventing partial updates.
Built-in Auth and Scheduling
Supports authentication, cron jobs, and backend workflows out of the box to handle common backend needs efficiently.
Extensible with Components
Offers reusable backend components for features like async work queues, counters, and geospatial queries, enabling rapid feature addition.
Use Cases
- Real-Time Collaborative Apps : Develop apps like chat platforms or live dashboards that require instant data sync and reactive UI updates.
- Dynamic Web and Mobile Apps : Build scalable apps with complex backend logic, including transactional data operations and integrations with external APIs.
- Rapid Prototyping and MVPs : Leverage Convexโs all-in-one backend to quickly develop and iterate on product ideas without managing infrastructure.
- Serverless API Development : Create secure, type-safe APIs with backend functions that integrate with third-party services like OpenAI, Stripe, or Twilio.
- Data-Driven Applications : Implement apps requiring consistent, real-time data views with strong transactional guarantees, such as e-commerce or inventory systems.
