The directory helps you select a focused check. The complete accessibility decision still belongs to the final page and the people using it.
Focused evidence is not a website certificate
A ratio, warning, outline, generated table, writing indicator, or timing calculation can answer a narrow question. No result on this page independently establishes complete WCAG conformance, legal compliance, or usability for every person.
Use the Accessibility Guides when you need standards context, examples, exceptions, and repair choices.
Before opening a tool
Are all ten tools free?
Yes. They are available without registration or a paid analysis API.
Can the directory scan a live website?
No. Each tool works with focused values, markup, text, or timing that you provide. This keeps its result explainable and avoids presenting a partial scan as a complete audit.
Why are HTML tools grouped together?
Headings, labels, links, image alternatives, and tables all depend on semantic relationships in markup, even though they support different user tasks.
Does a passing result prove accessibility?
No. It means the provided input met the specific rule described by that tool. Other requirements and real-user barriers may remain.
Need help interpreting a result?
Read the topic-specific guides for requirements, practical examples, repair decisions, and the manual checks that follow automation.
