Convex

Convex is a backend platform designed to simplify building and operating full-stack applications by providing a fully managed, real-time data layer and serverless compute environment. It handles data storage, synchronization, and backend logic so developers can focus on product features rather than infrastructure. Convex keeps client applications in sync automatically, enabling responsive, collaborative, and stateful user experiences without manual API or cache management.

Core capabilities include a strongly consistent document database, real-time queries, and automatic synchronization to connected clients. Developers write backend functions in TypeScript/JavaScript, which run in a secure, serverless environment with built-in authentication, authorization, and scheduling. Convex manages schema evolution, indexing, and data validation while exposing a type-safe API to frontend frameworks such as React, Next.js, and others. It also provides transactional semantics, optimistic updates, and conflict resolution to simplify complex multi-user workflows.
