Accessibility Insights
Verified working Aug 3, 2026
Tools for finding accessibility issues in web and Windows apps.
Accessibility Insights is a Microsoft accessibility testing project with a browser extension for Chrome and Microsoft Edge and a Windows desktop app. It helps developers find common accessibility problems, inspect UI properties, check color contrast, and review coverage against WCAG 2.1 AA guidance.
Why it stands out
- Covers both browser-based experiences and native Windows applications under one project.
- FastPass is designed for quick early triage rather than only full formal audits.
- Combines automated findings with visual explanations and fix-oriented guidance.
- Windows tool bundles accessibility inspection and contrast testing that are often separate utilities.
- Open-source Microsoft project with public GitHub repositories and community involvement.
Good to know
- The web testing tool is provided as a browser extension for Chrome and the newer Microsoft Edge, not every browser.
- The desktop app is specifically for testing Windows applications.
- FastPass focuses on common, high-impact problems and should not be treated as a complete manual accessibility audit.

Web and Windows app developers can catch accessibility defects during development before release. Run a quick FastPass check to uncover common high-impact issues in a page or app. Inspect Windows UI Automation properties while debugging desktop application behavior. Check contrast ratios and get practical guidance for fixing visual accessibility problems. Add accessibility checks into an agile QA workflow without starting with a full manual audit.
