How to check your website's accessibility for free

Real tools, what they actually catch, and honestly, what they miss.

Website accessibility lawsuits (ADA Title III in the US) are a real, growing risk for small businesses, not just large companies — and most people find out there's a problem only after getting a letter. The good news: checking your own site takes about five minutes with tools that are genuinely free, not trial-and-upsell.

Free tools that actually work

WAVE (Web Accessibility Evaluation Tool) A browser extension from WebAIM. Install it, click it on any page, and it overlays icons directly on your site showing missing alt text, contrast issues, heading problems, and more — visually, right where the problem is. Good starting point precisely because it's visual, not a wall of text.
axe DevTools browser extension Built by Deque, the same accessibility testing engine that powers Google Lighthouse and most commercial accessibility tools. Runs inside your browser's dev tools, gives a structured list of issues by severity.
Chrome Lighthouse (built into Chrome) Open DevTools (F12) → Lighthouse tab → run an audit → check the Accessibility score. Already installed if you use Chrome; zero setup.

What none of these actually catch

Here's the part usually left out of "free tool" lists: automated scanners like the ones above — including the axe-core engine underneath most of them — catch roughly 30-50% of real WCAG issues, by axe-core's own documented coverage. Things they structurally can't detect: whether alt text is meaningfully descriptive vs. just present, whether a page makes logical sense navigated by keyboard only, whether a screen reader user could actually complete a checkout flow. Those need an actual human trying to use the site that way.

So: run one of the free tools above today — it's a genuinely useful first pass and costs nothing. Whether you need to go further depends on your real exposure (how much traffic, how regulated your industry, whether you've already been contacted).

If you want a written report instead of reading a tool's raw output yourself — prioritized by severity, in plain English, with links to exactly how to fix each thing — that's the Accessibility Audit service: $19, 24h turnaround, same axe-core engine, honest about what automated scanning does and doesn't cover.
