Convex

What is Convex?

TypeScript backend with real-time sync and built-in AI workflows.

Who is Convex best for?

Convex is best for TypeScript developers building real-time apps who want database and server code in one backend.

• Apps written by coding agents

  Every write runs as one serializable transaction that retries on conflict, so code an agent writes without locks still holds up when many users hit it at once.

• Real-time apps

  Real-time sync pushes new data to every open screen, which suits chat, live dashboards and multiplayer apps.

• AI features and long jobs

  Ready-made components cover agent threads with vector search, retrying model calls and multi-step workflows that resume after a failure.

• Side projects and prototypes

  The free plan is sized so one or two developers can build and share a personal project without hitting its limits.

How much does Convex cost?

Convex is free to start, with pay-as-you-go usage on its Starter option, while Professional costs $25 per developer a month and Business & Enterprise starts at a $2,500 monthly minimum.

Business covers 1 to 50 developers with no per-developer fee; Enterprise, with unlimited developers, bring-your-own-cloud and annual commit discounts, is priced on request. Past the included amounts, Professional pays $2 per extra million function calls and $0.20 per extra GB of database storage. Usage is counted across all projects in a team. Priority support costs $1,000 a month and Premier support $2,000 a month, or 4% and 7% of usage if that is higher. Usage rates shown are for the US East (N. Virginia) region.

How do I connect Convex to my AI agent?

Convex MCP is Convex's official MCP server. Add it to your agent once, then ask it to query Convex tables and call backend functions while you code.

Gives your agent a view into your Convex backend, so it can read development data, look at deployments and run or debug functions as it writes code.

Terminal

$ claude mcp add convex -- npx -y convex@latest mcp start

It runs on your computer, so Claude Code starts it when it needs it.

Convex's setup guide covers the sign-in.

Then ask your agent

• Show the last 10 rows in the messages table
• Run the seedUsers function on dev
• List the deployments for this project

What are the best Convex alternatives?

Two tools on Recaply do Convex's job. Both are open source, so you can run them on your own server.

AppwriteOpen Source

Choose it when you want a permissive BSD licence and SDKs for web, Flutter, React Native and Apple apps in one backend

SupabaseOpen Source

Choose it when your data belongs in plain Postgres with SQL access and you want the option to run the whole stack yourself
