What builders ship
Podium builds from recent Yards. Each one made solo, and placed by the Yard's own ballots.

Every website is haunted. Links die, events expire, copyright years freeze, and nobody notices.

// How it works
Build the week. Vote the weekend. Crown on Sunday.
Claim a spot and check in before kickoff. Build solo Monday to Friday with any AI model, ship your repo and a demo, and over the weekend the builders rank a Champion while members pick their favorite. A new Yard runs the 1st and 3rd week of every month.

FAQ
Does it cost anything to join?
No. Claiming a spot and building in a Yard is free.
Can I use any AI model?
Almost always, yes. Bring whatever you use, or no AI at all. The theme is the constraint, not the model. A Yard can name a model (usually a sponsor's), and its page says so up front.
What if I can't make it?
Release your spot so the waitlist moves. And if you don't check in before kickoff, your spot releases on its own, so a full Yard stays a Yard full of builders.
Who picks the winner?
The builders. Everyone who ships opens the other builds and ranks their top 3, and the most points wins Champion. Members who didn't ship pick Members' Choice. No judging panel, nothing counted in public until voting closes.
What do winners get?
The Champion gets the Champion badge, a spot in the Hall of Fame, a featured writeup, and a year pinned to the home page. Some Yards add a cash prize, stated up front. Members' Choice wins its own badge.
