Accesserty DevCheck

Run browser-based accessibility checks with simulations, axe-core WCAG checks, AI semantic review, and PDF accessibility signals.

Accesserty DevCheck helps teams test web accessibility earlier, directly in the browser. It is built for designers, QA testers, frontend developers, PMs, content teams, and anyone who needs to understand whether a page remains usable for people with different access needs. What you can do with DevCheck: 1. Simulate accessibility barriers such as color vision differences, low vision, text spacing issues, visual field loss, dyslexia-like reading friction, and touch target conflicts. 2. Run automated axe-core accessibility checks on the current webpage. 3. Review categorized WCAG-related findings directly on the page. 4. Run AI-assisted semantic checks for link purpose, language marking, and image description quality. 5. Check selected local PDF files for common accessibility signals, including document language, tags, outlines, links, images, and form fields. 6. Test public websites, internal environments, authenticated states, and localhost pages during development or review. DevCheck is not a replacement for manual accessibility review or assistive technology testing. It helps teams find common issues earlier, discuss accessibility with more concrete context, and improve before release. Simulations, axe-core checks, and PDF checks run locally in the browser. AI Semantic Check is optional and user-triggered. When used, it sends extracted page text, link information, and selected images to Google Gemini directly with the user's own API key or through Accesserty's limited proxy for free usage. DevCheck does not send full DOM content, browsing history, form input, PDF files, or scan results for local checks.
