Accesserty DevCheck

Provides a Chrome extension for simulating scenarios (e.g., color blindness) and performing automated accessibility checks.

Accesserty DevCheck is a lightweight accessibility assistant for developers and designers. It helps you simulate real user limitations and identify accessibility issues early in development or during audits — all without needing to be an expert in WCAG. DevCheck bridges the gap between abstract compliance and tangible user experience by showing you how people actually struggle to use your site. What problems does it solve? - Developers don’t know what accessibility really feels like. - Automated testing tools feel abstract, technical, and disconnected - Designers and PMs don’t know what to test — or when. - Websites often fail in real-world conditions. - Accessibility work is reactive, not proactive. Who is it for? - Designers who want to test ideas for inclusiveness early - Frontend developers who need to build accessibly without guesswork - QA testers validating UX against real-world limitations - Product owners seeking to understand user experience beyond compliance
