Convex

Definitions

1. A reactive backend platform that combines a real-time database, serverless functions, and file storage into a single TypeScript-native service. Convex automatically syncs data to all connected clients in real time without requiring WebSocket setup, polling, or cache invalidation. Developers define their database schema and server functions in TypeScript, and the Convex client library provides fully typed, reactive queries that update the UI instantly when data changes. The platform handles transactions with strong consistency guarantees (serializable isolation), scheduled functions, and full-text search. Convex represents a new category of 'reactive backend-as-a-service' that eliminates the complexity of building real-time features, competing with Firebase and Supabase with a stronger type-safety story.

   In plain English: A backend platform where your app's data automatically syncs to all users in real time. Write your server logic in TypeScript and the database updates appear instantly in every connected browser.

   Example: Our collaborative editor uses Convex. When one user types, every other user sees the change instantly with zero extra code for syncing.
