What Accessibility Insights for Web is
Accessibility Insights for Web is a free, open-source browser extension for finding and fixing accessibility issues in websites and web applications. Its FastPass process is designed to identify common, high-impact problems in under five minutes and automatically checks approximately 50 accessibility requirements. FastPass also guides keyboard reviews with instructions, partial automation, and a visual helper for missing tab stops, keyboard traps, and incorrect tab order. Assessment helps people with HTML skills verify WCAG 2.1 Level AA conformance through instructions, examples, and fix guidance for approximately 20 manual tests. The extension supports page scans and CI/CD integration, and targets Chrome and the new Microsoft Edge on Windows, macOS, and Linux. With consent, it collects anonymized usage and crash-report information, with an opt-out setting. The free plan costs nothing. Accessibility Insights for Android is no longer downloadable, and existing installations no longer receive updates.
