About the event

One day. 8 h on the clock. Your own AI agent.

Free, online and solo. Open to developers anywhere in the world, aged 18 and over. Applications close Saturday, October 31, 2026 at 16:37 UTC.

How it works

  • Pick your start time. Start any time between Saturday, November 7, 2026 at 00:00 UTC and Sunday, November 8, 2026 at 23:59 UTC. Your clock begins when you click Start.
  • Two challenges. Split your time between them however you like.
  • Each Challenges will be award separately so you can focus only on one challenge if you want.
  • Everything in your browser. IDE, terminal, live preview and databases. Bring your own AI agent: Claude Code, Codex, Antigravity CLI, GitHub Copilot CLI and more, signed in with your own account. Nothing to install or pay for.

The challenges

1. Rescue and ship. A messy full-stack TypeScript app with bugs, security holes and an unfinished backlog. Get it working, make it safe, then ship what's missing.

2. Revealed on build day. You'll see it when your clock starts.

How you're judged

Engineers from companies that are hiring score every real submission. They look at your code, your tests and how you worked with your agent. Using AI is the point; using it well is what wins.
