Building with Claude Code, Codex, or Antigravity? We built a hackathon for you!
Season 3 signups are open: Build the Loop.
Your agent writes the code; the open-source TestSprite CLI checks it against your live app.
Write → verify → fix → verify.
The loop you run is what you submit.
$5,000 pool.
$3,000 goes to the best projects over 7 days.
The other $2,000 is a standing bounty: spot an improvement for our open-source CLI, open a PR, and we pay $100+ per merged PR. No deadline on that one. It runs till the pool's gone!
