Accessibility Checker & Report
Find what's broken on any page. A browser extension for Chrome and Edge — open a page, click once, and get a plain list of what's wrong: the rule, the element, and how to fix it. Export a report you can hand to a client.
For whoever has to answer for the site — an agency, an in-house team, or you on your own. You do not need to be the person who wrote the code.

One click, no setup
Install, open a page, click the icon. No account, no dashboard, no config file. Scans run locally in your browser.
Real rules, not opinions
Built on axe-core, the open-source engine used by most accessibility tooling. Checks WCAG 2.0, 2.1 and 2.2 at levels A and AA.
A report you can send
One file, self-contained, opens in any browser. Groups findings by severity, lists the failing elements and links to the rule. Print it to PDF if you need to.
Says what it can't do
Automated testing catches roughly a third of real accessibility issues. The extension says so on every report, because a clean scan is not a legal compliance statement.
Pricing
One price. Pay once, keep it.
Install
Not in the Chrome Web Store or the Edge Add-ons store yet — both listings are in review. Until they go live, download the current build and load it unpacked. It takes about a minute.

Store links will appear here once both listings are approved. Questions, bugs, or anything unclear: email support@zennel.dev.
Questions
Does the free version expire?
No. Free stays free. You only pay if you want the full list and report export.
Does my page content leave my computer?
No. The scan runs inside your browser. The only network request the extension makes is to check your license key, and it sends nothing about the page you scanned. See the privacy policy.
Will this make my site legally compliant?
No, and nothing automated will. Tools like this catch roughly a third of real issues. A clean report means the automated checks passed — it is not a legal opinion and not a compliance certificate. Manual testing with a screen reader and real users is still the only way to know.
What happens if I get a new laptop?
A Pro license covers up to 3 devices. You can deactivate one from inside the extension and activate another with the same key.
Refunds?
Email support@zennel.dev within 14 days and you'll get your money back, no questions asked. Payments and refunds are handled by Creem, our merchant of record.
