about this event
Build it with an agent. Verify it with Kane. A one-day, in-person hackathon for developers who build with AI coding agents, and want to see what happens when you put a real verification layer next to them. 50 builders. One room in San Francisco. $5,000 in prizes. Hosted by TestMu AI.
The Challenge: Build a working app with any AI coding agent. Use Kane CLI to verify it works. Ship by 6 PM. That's the whole brief. The app can be anything you want: a tool, a dashboard, a side project you've been meaning to start, a game, an internal utility, a weird experiment. The only constraints are: Kane CLI verifies the app, at a minimum at demo time. The strongest submissions wire Kane into the agent itself: a hook that fires Kane on save, an agent that reads Kane's NDJSON output and iterates, a spec that compiles down to Kane flows. It runs, it ships, and you can demo it live at the end of the day. You can work solo or in teams of up to four. Bring a laptop and your usual stack. Everything else is on us.
Before you arrive: Bring the agent you already use. Any AI coding agent works: CLI agents, IDE agents, chat-based agents, an MCP-driven setup, or one you built yourself. Have it installed and signed in before you show up. Install Kane CLI and run one flow. Run npm install -g @testmuai/kane-cli , then try one of the examples from the docs. If fifty people are doing fresh npm installs at 10:05 AM, the hackathon loses an hour. We'll send a cheat sheet with your confirmation email. You'll have free Kane CLI Pro access for the day, so don't worry about hitting limits during the event.
Prizes: $5,000 USD in cash, split across three winners. Every winner also gets the full perks stack. 1st Place $2,500. 2nd Place $1,500. 3rd Place $1,000. In addition to the cash, every winning team receives: A 1:1 with the TestMu AI founders, design partner status with input on the Kane CLI roadmap, 3 months of Kane CLI Pro, a featured post on the TestMu blog, a showcase feature on testmuai.com/kane-cli/showcase, and amplification across TestMu and dev.to channels.
