I had a bunch of extra Fable credits, so I spent around $10k in api costs doing autoresearch loops on the top 200 github repos with frontends. The goal was to speed up the frontend / improve the lighthouse score.

I distilled the wins down into a leaderboard of most common improvements, then built a wrapper that iterates through them. It ties into your claude/cursor/codex subscriptions, so there's no subscription or payment - it should "just work" as long as you have a sub to one of those.

It will ask you to submit your score / thinking trace at the end, but that's optional. Lemme know what you think / if it helps you out!
