Convex Has a Free API — The Reactive Backend for Modern Apps

What if your backend automatically pushed updates to every connected client — no WebSockets, no polling, no cache invalidation?

Convex is a reactive backend where queries are live by default.

Why Convex

• Reactive queries — data updates push to clients automatically
• ACID transactions — strong consistency
• TypeScript everywhere — full type inference from backend to frontend
• Built-in auth, file storage, scheduled functions

const tasks = useQuery(api.tasks.list); // Auto-updates when data changes!

When any client adds a task, ALL connected clients see it instantly. No WebSocket code needed.

Real Use Case

A collaborative tool deleted 3,000 lines of sync/polling code after migrating to Convex — real-time sync worked out of the box.
