ProbeLayer
Built at Google I/O Hackathon · May 23, 2026 · San Francisco, CA
ProbeLayer finds where real users get stuck and where bad actors get through before launch. It tests live web flows with distinct personas, captures screenshots / DOM signals, and returns clear UX, accessibility, and abuse findings with fixes. It's a synthetic user testing platform, that splits into 2 multi-agent teams: UX and Security/Vulnerability problems, with clear fixes.
