Auth & InfrastructureOpen-source reactive backend platform with real-time TypeScript database, built-in auth, file storage, and automatic client-server sync for fullstack apps.
Convex is an open-source reactive backend platform where everything is expressed in TypeScript, from database schemas to queries and APIs. It automatically handles real-time data synchronization between clients and servers via WebSockets, eliminating the need for manual state management or cache invalidation. The platform includes built-in features like authentication (80+ OAuth integrations), cron jobs, file storage, vector search, and AI workflow support. Convex can be self-hosted or used as a managed service, making it ideal for startups and developers who want to move fast without managing infrastructure.
