Breaking Apps Hackathon Winners

The Breaking Apps Hackathon ran for four weeks, sponsored by Bug0. The brief was simple: write Passmark tests for any web app, then publish a Hashnode article about what you found. The entries made the case for plain-English tests run by AI. They catch the bugs selectors miss. Thanks to everyone who joined.

Here are the winners.
