Accessibility Tools

Helpers for building accessible websites to WCAG 2.2. Check colour contrast and generate accessible palettes, simulate colour-vision deficiencies, inspect heading structure and link text, run basic automated HTML checks, test text-spacing and target-size requirements, and use interactive checklists for alt text and keyboard testing. Automated checks find only some problems, so every tool explains its limits and reminds you that a manual audit with assistive technology is still needed.
