Our verdict on Accessibility Insights for Web
Accessibility Insights for Web is a free, open-source browser extension from Microsoft for developers assessing websites and web applications. It runs in Chrome and Microsoft Edge on Windows, macOS, and Linux. The tool combines automated checks powered by axe-core with assisted keyboard tab-stop testing and a broader workflow covering automated, assisted, and manual tests. Its audience is teams that need a guided way to inspect accessibility issues directly in the browser.
Its assessment workflows are the main strength. FastPass provides automated checks, while Assessment supports WCAG 2.2 Level AA review. Quick Assess covers selected WCAG 2.1 Level AA requirements. Visual highlighting helps locate accessibility failure instances on the page, and users can save and load in-progress assessments. Results can be exported as HTML or JSON, giving teams a portable record of findings.
The tool also connects assessment work to issue tracking through GitHub and Azure Boards repositories. That makes it suitable for page-focused reviews where developers inspect a site, document findings, and file follow-up work. It is less suited to organizations seeking scheduled scanning or API access, and its primary scope is individual pages rather than a wider monitoring system. Choose Accessibility Insights for Web when free, open-source browser workflows and guided WCAG assessments are the priority; choose another tool when recurring scans or programmatic access are central requirements.
