Score: 7.7/10 (Innovation: 8, Technical: 8, Documentation: 6, Utility: 7)

FuckUI is a REPL for browsers that makes web pages 'legible' to AI agents by converting them into numbered action lists with stable references, enabling reliable automation across logins, CAPTCHAs, and complex portals without screenshots or brittle selectors. It's interesting because it reimagines browser automation as a native conversation for agents, with persistent sessions and human handoff for authentication barriers.

Target audience: backend devs, devops, ai engineers
