Misfeature beta
Vibecoding makes it practical to build ideas that used to be too absurd to attempt. Misfeature turns that into an anti-hackathon.
Current Challenge
Worst Date Picker
A classic. The most-attempted, least-solved component on the web — and the obvious first round for an anti-hackathon. Build one that is confidently wrong, opinionated about the wrong things, and still technically lets someone pick a date.

Challenge brief
Prompt
Official
Build the worst date picker imaginable: start from something that looks like a calendar, then quietly betray the user with every click. It should still, technically, let someone pick one calendar date.
Submission rules

Make it interactive enough for visitors to judge it on the spot.
