Description

Convex provides a reactive database, server function runtime, and client libraries to fetch data and run business logic with strong consistency using TypeScript. The repository contains the backend code (Rust crates) and related npm packages for UDFs and system functions, and supports both a Docker/prebuilt-binary self-hosted deployment and a managed cloud offering. It is designed to simplify building and scaling dynamic, real-time applications and includes guides for self-hosting and building from source. Development is led by the Convex team and the project welcomes community contributions.
