About Accessible Web Kit

Last updated 2026-10-13

Accessible Web Kit is a free set of web accessibility tools for developers, designers, agencies and the people who buy or approve websites: a color contrast checker, HTML checkers built on axe-core, WCAG, Section 508 and ADA checklists, ARIA references, and generators for VPAT-style conformance reports and accessibility statements. Each page does one job and works straight away: there is no account and nothing to install.

What the tools check, and what they do not

Standards from the source. Success criteria, levels and thresholds come from the W3C’s WCAG 2.0, 2.1 and 2.2 and WAI-ARIA 1.2; U.S. rules come from ada.gov and the U.S. Access Board. Each page lists its sources with the date we checked them.
Automated rules from axe-core. The HTML checkers run the open-source axe-core engine, unmodified, inside your browser.
No compliance verdicts. Automated checks find only part of accessibility problems, so no tool here says a page is “accessible” or “compliant”, and nothing here is legal advice. The checklists help you record the manual checks that a person has to do.

How it works

Everything runs in your browser. What you type or choose stays on your device; nothing is uploaded.
Results are computed, not typed in. The examples on each page are produced by the same code the tool runs, and the code is tested against independently calculated results.
Third-party material used on the site is listed on the credits page.

If a tool gives a wrong result, please tell us through the contact page.
