Web Accessibility Testing

Web accessibility testing can feel overwhelming at first, but this collection gives you several sensible entry points depending on what you need to check. If you’re reviewing a page in the browser, tools like WAVE, axe DevTools, and Microsoft’s Accessibility Insights help surface common accessibility problems and point you toward the affected elements, while still leaving room for human judgment. For the especially common question of whether colors are readable enough, Accessible Web’s Color Contrast Checker and Colour Contrast Analyser keep things focused, with WCAG contrast results, AA and AAA pass/fail guidance, and, in the desktop app, helpful extras like screen color sampling and color vision deficiency simulation.

There’s also strong support here beyond one-off scans. W3C WAI and The A11Y Project are excellent places to build your understanding of WCAG, testing methods, checklists, and practical implementation across design, development, content, and education work. For teams with broader needs, Axe Platform brings together automated checks, guided manual testing, integrations, monitoring, reporting, and training, while The Accessibility Guy focuses on consulting, training, and remediation for documents, course materials, web content, and accessible PDFs. Taken together, these resources make the category useful whether you’re fixing a single color pairing, learning the fundamentals, or building a more mature accessibility process across an organization.
