The market for accessibility tools has exploded in recent years. But how do you choose the right tool for your needs? Should you use a free browser extension or invest in an enterprise solution?

In this guide, we compare the most popular web accessibility tools – from simple Chrome extensions to complete platforms for continuous monitoring.

We cover strengths and weaknesses, pricing models, and provide recommendations based on different use cases.

Categories of tools

Accessibility tools can be divided into several categories:

1. Automated scanners

Scan entire websites and find problems automatically. Good for overview and continuous monitoring.

2. Browser extensions

Analyze one page at a time directly in the browser. Good for developers and spot checks.

3. Design tools

Plugins for Figma, Sketch, etc. Check contrast and accessibility in the design phase.

4. CI/CD integrations

Run tests automatically at deploy. Stop inaccessible code from reaching production.

5. Screen readers

Technically assistive technology, but invaluable for testing the real experience.

Most organizations need a combination. Automated tools for breadth, manual for depth.

Lighthouse CI

•Type: CI/CD tool

Recommendation for CI/CD:

Run axe-core in your test suite to catch problems early. Add Pa11y or Lighthouse CI as gating in deploy pipeline.

Our recommendation

For individual developers:

Start with WAVE or axe DevTools (free). Learn what the problems mean. Test manually with keyboard.

For teams:

axe DevTools Pro for developers + axe-core in CI/CD + Xrayd for overall monitoring.

For agencies:

Xrayd or similar platform that can handle multiple client sites, generate reports, and provide early warnings.

For enterprise:

Siteimprove or similar for scalability + internal processes for manual review.

Most important:

No tool replaces manual testing. Automated tools find 30-40% of issues. Test with keyboard, screen reader, and – if possible – real users with disabilities.

Test your site's accessibility

Frequently Asked Questions

Are automated tools enough?+

No. Automated tools find about 30-40% of accessibility issues. They miss context-dependent problems, screen reader experience, and cognitive accessibility. Combine with manual testing.

Which tool is best for beginners?+

Lighthouse (built into Chrome) is free and simple. For deeper analysis, WAVE and axe DevTools are good starting points. Xrayd is best for scanning entire sites automatically.
