Check any page for accessibility problems

Paste a URL. We fetch that one page, check its HTML against the same list of problems the plugin uses, and show you the exact markup responsible. No account, no email, nothing kept for more than an hour, and we respect the site's robots.txt.

What this tool can and cannot do

It finds mechanical problems: missing alt text, links and buttons with no accessible name, form fields with no label, heading levels that skip, tables without header cells, frames without titles, positive tabindex, zoom-blocking viewport settings, alt text that is really a file name, and more. Every finding quotes the line of HTML it is talking about, so you can check it yourself in seconds.

It cannot see colour contrast, judge whether alt text is actually helpful, or know how a page behaves in a screen reader. It is not a compliance check and nobody can certify a website from an automated scan. The long version is here.

If you look after more than one site

Running a URL through a page like this does not tell you what broke since last week. The agency edition of our WordPress plugin watches every client site on a schedule, emails you when something new appears, and produces a report you can hand over under your own name.
