VIBELADDER is a rated ladder for people who build with AI. Every leaderboard in AI coding ranks the models. This one ranks the person using them.
HOW A ROUND WORKS
At 17:00 Budapest time (15:00 UTC) a task drops on vibeladder.dev: a small, complete app, kept secret until that minute. You get 90 minutes and any AI tool you like: Claude, ChatGPT, Cursor, Copilot, anything. You submit one self-contained HTML file that works offline, plus the transcript of your session with the AI.
Entries are compared head to head by an LLM judge that drives both apps through the interface only, the way a user would. It never reads the source code. Every comparison feeds one rating, and the whole table is recalculated from scratch after each round.
WHY THIS ROUND
Round 4 is the Season 1 finale. After three rounds the top two are 33 points apart and have beaten each other once each. The title is decided on Saturday.
If you have never played, that is fine. The rating is not points you collect, so there is nothing to catch up on, and one good result puts you on the board next to people who have played all season.
You do not need to be a developer. The round 2 winner used three prompts. The round 1 winner never typed a line of code. What gets measured is how clearly you describe what you want, how you check what the AI gives you, and how you use the time.
WHAT YOU NEED
A free seat. Sign in with Google or GitHub, pick a nickname. Your login stays private, the nickname is the only thing shown.
90 minutes on Saturday from 17:00 to 18:30 Budapest time.
Any AI tool, and a way to export or share your session.
EVERY RESULT SHIPS WITH ITS RECEIPTS
After each round we publish both apps so you can play them, the judge's reasoning word for word, and the winner's session prompt by prompt. When our own tooling got something wrong, we published the correction on the same page. You can read all three rounds so far at vibeladder.dev/leaderboard.html before you decide.
No prizes this season, on purpose. The point is the rating, and seeing how other people actually work with these tools.
