Is the Pandus extension free?

Yes. Checking pages and the visual tools work without an account. A free Pandus account adds the results of the weekly check and saving checks to your site.

Does the extension send my pages anywhere?

No. The check runs in your browser. Results go to Pandus only when you click "Save to Pandus", and then only the problems found and the element snippets, not the page.

Why check in the browser if Pandus checks my site every week?

The weekly check sees what a visitor without an account sees. The cart with products in it, the checkout, the customer account and pages on a staging server need a login or a state that only your browser has.

Which browsers does it work in?

Chrome, Edge, Brave, Opera and other Chromium browsers, and Firefox 128 or newer.

How is it different from axe DevTools, WAVE or Lighthouse?

It uses the same open axe-core engine as many tools, but explains each problem for the business owner in seven languages, separates what WCAG 2.2 AA requires from advice, and connects to your weekly monitoring.

Does a clean result mean my site meets the EAA?

No. An automated check finds part of the problems. Use the tools for a manual review, and see the result as a starting point, not a full audit and not legal advice.

Pandus browser extension 1.0.0

Free. Chrome, Edge, Brave, Opera and Firefox. In the extension stores: coming soon.

Download for Chrome, Edge, Brave, Opera (.zip) Download for Firefox (.zip)

The Pandus extension checks the page you are on against WCAG 2.2 AA — the level the European Accessibility Act, the German BFSG and the ADA rely on — and explains every problem in plain words, in English, Ukrainian, German, Polish, Czech, Romanian or Russian. It runs in your browser, so it also checks pages behind a login: the cart with products, the checkout, the customer account, a staging site.

What it does

Check this page in one click. More than 90 automated rules, the same as the weekly Pandus check. Problems are grouped by rule, the most severe first, with why it matters for your customers and how to fix it.
Show the element. Click "Show" and the page scrolls to the element and outlines it.
Required apart from advice. WCAG 2.2 A/AA problems come first; AAA and best practices are shown separately as advice.
Copy for the developer. The whole list as Markdown for a ticket in Jira, Trello or a message.

Tools for the manual review

Automation finds part of the problems. The tools help with the rest:

Tool	What it shows	WCAG
Tab order	Numbers and a line in the order keyboard focus moves	2.4.3, 2.1.1
Headings	The outline screen reader users jump through, skipped levels in red	1.3.1, 2.4.6
Landmarks	Header, navigation, main content, footer	1.3.1
Images and alt text	The text read for each image, missing ones in red	1.1.1
Text spacing	Larger line, letter and word spacing	1.4.12
Zoom 200%	The page enlarged twice	1.4.4
Narrow screen	The page in a 320 px window	1.4.10
Colour vision	Protanopia, deuteranopia, tritanopia, no colour, blur	1.4.1
Contrast	Ratio of two colours, picked from the page	1.4.3, 1.4.11

How to install

Until the extension is listed in the Chrome Web Store and on addons.mozilla.org, install it from the zip above:

Chrome, Edge, Brave, Opera: unpack the zip, open chrome://extensions, switch on Developer mode, click Load unpacked and choose the folder.
Firefox: open about:debugging#/runtime/this-firefox, click Load Temporary Add-on and choose manifest.json from the unpacked folder. A temporary add-on is removed when Firefox restarts; the listing on addons.mozilla.org removes this step.
Pin the Pandus icon to the toolbar. Click it, or press Alt+Shift+A, on any page.

Privacy

No tracking, no analytics, no cookies. The extension asks only for the active tab when you click it, and for access to pandus.online to talk to your account. Checks stay in your browser until you save them.
