lo-eyes
Spins up Playwright in headless Chromium to run frontend accessibility audits straight from your Claude chat. You get four tools: screenshot any page at iPhone, iPad, or desktop viewport sizes, scan full pages into chunked viewport pieces with a RAG manifest, audit for WCAG contrast and touch target violations with S+ grading, or list device presets. The audit catches overflow elements, sub-12px fonts, touch targets below Apple's 44px minimum, and broken heading hierarchies. Built by Like One Foundation as a nonprofit project. Works over stdio transport and includes a CLI wrapper if you want to run it standalone. Change the BASE_URL environment variable to point at whatever site you're testing.
