Welcome, hackers
Free AI coding for your hackathon build.
A coding agent in your terminal. No API key to buy, no credit card, no setup beyond one command.
Based on the Pi agent harness by Mario Zechner.
Needs Node 22.19 or newer. Check with node -v.
What you get
A daily allowance of free coding help, paid for by tasteful terminal ads. Ad content never enters the model's context. The allowance resets every day, for the whole hackathon.
