Accessibility Scanner that gives more & cares more.

Zeniscan crawls the real, live pages of your site — your homepage, key landing pages, cart and checkout flow, contact forms — using a full browser engine, the same way a real visitor would load the page. We run an open-source accessibility testing engine also used inside Chrome DevTools and by accessibility teams at large companies, checking against WCAG 2.0, 2.1, and 2.2 at the A and AA levels— the same standard referenced in US ADA case law and the UK's own accessibility guidance.

Every issue we report ties back to a specific WCAG success criterion and a specific element on your page — not a vague score with no explanation. We translate that into plain language and prioritize it, so you know what to fix first and why it matters, not just that something's "wrong."

This matters enough that we won't round up: automated tools, including Zeniscan, reliably catch things like missing alt text, poor color contrast, missing form labels, broken heading structure, and keyboard-trap issues. These are common, real, and often exactly what a demand letter cites.

What automated tools can't fully judge is meaning— whether an alt description is actually useful, whether a page makes logical sense when read aloud by a screen reader, whether a complex interaction is genuinely usable without a mouse. That kind of judgment needs a human, ideally one who uses assistive technology themselves. That's why Pro plans include a free Consultant Review, and why we say plainly — in the scan, the report, and here — that Zeniscan is a strong, fast first pass and an ongoing monitor, not a replacement for expert judgment on your highest-stakes pages.

You may have seen widgets that promise one-click compliance — a small accessibility icon that adds a floating menu with font-size and contrast controls. We want to be straight with you about what those do and don't do, because it affects a real decision you're making with real money.

Overlay widgets generally work by adjusting your page's appearance and some ARIA attributes in the visitor's browser, after the page has already loaded— they don't change your site's underlying code. That means the actual barrier — a form with no label, an image with no alt text, a button a screen reader can't identify — is usually still there underneath. Several overlay-widget vendors have themselves been named in accessibility lawsuits, and businesses that relied entirely on a fully-automated overlay fix have still gone on to receive demand letters and face compliance complaints — the widget patched the surface, not the underlying problem the law actually cares about.

Zeniscan doesn't sit on top of your site pretending the issues aren't there. We find the real ones, in your actual markup, and give you — or your developer — exactly what needs to change. And unlike a fully-automated overlay fix, you're not left guessing whether the fix actually holds up: Pro plans include a free Consultant Review, where a real person who works with assistive technology checks the judgment calls an automated tool can't make reliably. On any plan, you can request a fix quote directly from a report and have the work done for you, instead of a script quietly papering over the problem in the visitor's browser. That's slower than installing a widget. It's also the version that holds up if someone ever actually looks closely, which in this category, eventually, someone does.

Websites change constantly — a new product page, a redesigned checkout, a new blog post with an unlabeled image. A scan is a snapshot of one moment. That's why paid plans include recurring rescans rather than a single report: new issues get caught close to when they're introduced, not months later when they've already been live and visible to every visitor and every search crawler.

We've kept the page, site, and rescan limits on every plan generous on purpose — monitoring only works if you're not rationing it. See current limits on pricing.

We're actively building semi-automated fixes and fix suggestions powered by AI — planned for release over the next couple of months. Every subscriber on a paid plan gets new features as they ship, automatically, at no extra cost and with nothing to turn on — not held back for a separate tier or a future price increase.

Zeniscan is an automated scan, not a legal opinion, and it doesn't guarantee ADA or Equality Act compliance or immunity from a claim — nobody selling you a tool honestly can promise that. What we can promise is a real, specific, prioritized list of what's actually wrong on your site, explained in language you don't need a lawyer or a developer to understand, kept current as your site changes. See why this matters in the first place if you haven't already, or just run a free scan and see what it finds on your own site.
