Free Accessibility Tools

Free web accessibility tools

Practical, genuinely-free tools to test and improve your site's accessibility — built by a team that does real WCAG remediation, not overlays. Use them to find issues fast, then fix the code that matters.

Why we give these away

Curbcut makes small-business websites ADA and WCAG 2.1 AA compliant with real, hand-built remediation. These tools are the honest front door to that work: they show you where your site stands today, in plain terms, without a sales wall.

They're also a useful reality check. An overlay widget promises instant compliance and doesn't deliver it. A scanner is more honest — but even the best automated check only catches about 30–40% of WCAG issues. The rest need a human with a keyboard and a screen reader. Our tools are built to make that boundary clear, not to hide it.

How to use them together

When you're ready to actually conform — and have it hold up if a demand letter arrives — a full audit is the next step.

Frequently asked questions

Are these accessibility tools really free?

Yes. Every tool here is free to use with no signup to start. For the website checker, you can run a scan and see your top issues for free; a detailed, itemized report is available by email. There's no charge and no obligation.

Will these tools make my website ADA compliant?

No single tool can. Automated checks catch roughly 30–40% of WCAG issues — they're great for finding obvious, high-volume problems fast, but real compliance needs manual testing with a keyboard and screen reader. Use these to triage, then get a full audit to actually conform.

What's the difference between these tools and an accessibility overlay?

These tools measure accessibility so you can fix the underlying code. Overlays try to patch problems at runtime with JavaScript and have repeatedly failed to stop lawsuits. We don't sell overlays — we help you fix the real thing.

Do you store the URLs or images I test?

The client-side tools (contrast, palette, simulator, statement and VPAT generators) run entirely in your browser — nothing is uploaded. The website checker sends the URL to our scanner to fetch and analyze the page; we don't publish or sell what you scan.

Want a real answer, not just a scan?

Our free scan is human-reviewed: we run the automated pass, then a specialist tells you what it missed and what compliance actually takes.
