FAQ
Answers to common questions about getting started and building with Convex.
Copy the setup prompt above into your coding agent (Claude Code, Codex, Cursor, or Copilot) and ask it to build a new app with Convex. Prefer doing it by hand? Pick your framework in the Convex quickstarts or build a real-time chat app with the tutorial.
Join the Convex Discord and post in the #hackathon channel. Ask questions, share what you’re building, and get unstuck fast. The team and community are there to help you ship.
Sometimes we provide codes for hackathon participants. Got a code? Sign in to your Convex dashboard, pick the team you want to upgrade, then go to Team Settings → Billing and enter it.
No. Convex holds the provider credentials, so there’s no key to get, store, or rotate. Your action signs in with a short-lived token scoped to your deployment. You need a paid plan (your hackathon coupon covers this) and Convex 1.45+. Read the setup guide.
