Convex

Convex is a TypeScript-first backend where your database queries, mutations, and business logic all live in the same codebase as your frontend. It handles real-time synchronization automatically, so changes to the database instantly reflect in the UI without manual subscription management. The platform includes authentication, storage, scheduling, and vector search as built-in features.

Ideal for TypeScript applications demanding real-time collaboration features and responsive UIs. Convex appeals to full-stack teams building modern applications with live updates where users see data changes instantly, such as collaborative editors, dashboards, or messaging apps.
