Convex is an open-source reactive database and backend platform. It is designed to give developers everything needed to build fast, reliable and dynamic web applications without complex backend engineering or database administration. The platform lets teams express their entire backend in pure TypeScript, covering database schemas, queries, authentication and APIs, with real-time consistency across frontend code, backend code and database state.
The platform's technical scope includes reactive databases, real-time synchronisation, vector search, AI workflows, file storage and distributed storage systems. It is built to work seamlessly with AI coding agents, and is aimed at teams building the next generation of web applications in the developer tools and software development sectors.
The engineering team behind Convex includes engineers from Dropbox who led exabyte-scale storage projects, and members who have built some of the world's most popular web apps. The group has also designed custom global databases handling trillions of records.
