What is Convex

Convex is a backend platform that gives you everything needed to build modern web and mobile applications. It includes a real-time database, serverless functions, file storage, and built-in features like authentication and scheduling. Unlike traditional backend setups, Convex updates your app automatically whenever data changes, without requiring complex code.

The platform is built around TypeScript, which means you get full type safety from your frontend to your backend. This reduces errors and makes development faster. Convex also includes vector search for AI applications, webhooks for integrations, and components that add functionality with simple commands.

There is a free plan for individual developers and small projects, plus paid plans for teams that need more resources and support. Self-hosting is also possible with the open-source version.

FAQ's About Convex

Yes, Convex offers a generous free plan that supports up to 6 developers and 20 projects. The free plan includes substantial resources like 1 million function calls per month, database storage, and file storage. You can build and run production apps on the free tier, and only upgrade when you need more resources or team members.
Convex stands out with its TypeScript-first approach and automatic real-time synchronization. Unlike Firebase which uses multiple separate products, or Supabase which focuses on SQL databases, Convex provides a unified platform where your backend code lives alongside your frontend. It offers better type safety, simpler real-time updates, and doesn't require manual cache management or WebSocket setup.
Yes, Convex is open-source and can be self-hosted on your own infrastructure. The platform works with various hosting providers including Fly.io, Vercel, and AWS. You have full control over your data and can migrate away if needed, avoiding vendor lock-in that some other platforms create.
Convex works seamlessly with React, Next.js, Vue, Svelte, and other modern JavaScript frameworks. The backend is written in TypeScript, and there are official client libraries for JavaScript, TypeScript, Python, and Rust. You can integrate Convex into existing projects or start fresh with any of these technologies.
Yes, Convex automatically scales to handle your traffic without any configuration. The platform is built by the team that scaled systems at Dropbox and handles everything from database queries to function execution. You can grow from one user to millions without worrying about server management, load balancing, or database optimization.
