The 10 Best Accessibility Tools for Designers in 2026

Last updated: August 2026

Accessibility gets treated as an engineering concern and then fails for reasons decided in the design file — insufficient contrast, colour as the only signal, focus states nobody drew, headings chosen for size rather than structure.

Ten tools that catch those before they reach code.

Inside your design tool

Stark is the most widely used accessibility suite for designers, working inside Figma. Contrast checking, colour-blindness simulation, focus order annotation, alt-text management, and touch-target checks — all while you're designing rather than after.

Focus order is the underrated feature. Almost nobody designs it, so developers invent it, and the result is a tab sequence that jumps around the page unpredictably.

Accented is a lightweight accessibility testing tool for quick checks.

Contrast and colour

Colour Contrast Analyser from Vispero is the free desktop standard. Eyedropper any two colours anywhere on screen and get the ratio against WCAG AA and AAA. Because it works outside the browser, it checks screenshots, prototypes and native apps too.

Accessible Brand Colors takes an existing brand palette and shows every combination as a pass/fail grid. Valuable precisely because it works with colours you're stuck with.

ButtonBuddy handles accessible button colours across every state — default, hover, focus, disabled, and the focus ring, which is the one almost everyone forgets.

Testing in the browser

Polypane is a browser built for development that shows multiple viewports simultaneously and runs accessibility checks continuously — contrast, heading structure, ARIA, focus order, colour-blindness simulation, reduced motion.

For anyone who reviews implemented work, this catches more in a single pass than anything else here.

Superposition extracts design tokens from a live site, useful for auditing whether implementation matches the intended system.

What tools cannot do

Test with the keyboard. Unplug your mouse and complete a core task. If you can't tab to something, or focus disappears, or a modal traps you — that's a bug no automated checker will report.

Check at 200% zoom. Layouts frequently break, and WCAG requires reflow.

Turn on a screen reader once. VoiceOver on macOS, NVDA on Windows. Ten minutes with your own product is more instructive than any checklist.

A practical design-stage checklist

1. Body text meets 4.5:1, large text meets 3:1
2. Colour is never the only way information is conveyed
3. Focus states are designed, not left to the browser default
4. Touch targets are at least 44×44px
5. Headings follow a logical structure rather than being picked for size
6. Form fields have visible persistent labels, not placeholder-only
7. Error messages say what to do, not just that something is wrong
