Accesserty DevCheck by Accesserty

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:

• Simulate accessibility barriers such as color vision differences, low vision, text spacing issues, visual field loss, dyslexia-like reading friction, and touch target conflicts.
• Run automated axe-core accessibility checks on the current webpage.
• Review categorized WCAG-related findings directly on the page.
• Run AI-assisted semantic checks for link purpose, language marking, image alt text quality, and suggested alt text improvements.
• Check selected local PDF files for common accessibility signals, including document language, tags, outlines, links, images, and form fields.
• 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. It sends extracted page text and selected images to Google Gemini, either directly with the user's own Gemini API key or through Accesserty's limited free proxy. It does not send full DOM, browsing history, form values, PDF files, or scan results.
