Things you can run yourself, with a clear statement of where each one stops being useful.
Paste a URL and see in seconds what a scanner can genuinely decide.
Open the checkerAccessibility checker
Enter a URL and it fetches the page and reports what the HTML genuinely reveals: images without alternative text, a missing language attribute, broken heading order, unlabelled form fields, generic link text, icon-only buttons without accessible names, duplicate IDs, a viewport that blocks zoom, and missing autocomplete on fields whose purpose is unambiguous.
It is a real check, not a simulation — and it decides a minority of WCAG 2.2. It cannot see focus order, focus traps, whether errors are announced, or what a screen reader says. Those limits are printed beside the result, because a check that overstates itself is worse than no check.
Nothing is stored: not the URL, not the result.
It is run against this site too
Every build runs the same checker over every page of uxerfy.com and fails if anything is flagged. A site selling accessibility auditing should not be able to ship a page its own check would catch.
What is not here
A contrast checker, an alt-text checker and an accessibility statement generator are the obvious next ones. They are not here yet, and this page will not list them until they work.
For everything automation cannot decide, the guide on testing your own site walks through the sequence by hand — keyboard, screen reader, zoom and forms — and finds more than any automated pass will.
