Accessibility tools for developers, designers, and QA teams

Which accessibility tool do you actually need?

Most accessibility work splits into four jobs, and the tool you want depends on which one you are doing. Automated checkers are excellent at the mechanical layer and cannot judge meaning, so treat any clean report as a starting point rather than proof of conformance. The automated versus manual testing guide explains where that line falls.

Developers shipping a fix

Start with the URL accessibility auditor for a page-level scan, the contrast checker for WCAG 2.2 and APCA ratios, and the heading analyzer to catch a broken document outline.

Designers building a system

The accessible colour palette generator produces WCAG-aware palettes and previews them in real UI states, so contrast is settled before handoff rather than caught in review.

QA and audit teams

Track findings against every criterion with the interactive WCAG 2.2 checklist, then turn them into a shareable document with the accessibility report generator.

Compliance and procurement

Publish where you stand with the accessibility statement generator, and check a vendor’s claims against the overlay detector if they rely on an accessibility widget.

What these tools cannot tell you

No scanner can tell you whether alt text describes the right thing, whether focus order preserves meaning, whether an error message helps someone recover, or whether a custom widget works with a screen reader. Those need a keyboard, a screen reader, and a person. Use these tools to clear the mechanical failures fast, then spend the time you saved on the screen reader testing and keyboard accessibility passes that actually decide whether the product is usable.
