Questions, bug reports and tool requests — we read every message.
When you report a problem, include the tool you were using and the page address (URL) you were checking — that is usually enough for us to reproduce it.
Before you write
- The tools need no account and store nothing about you — see our Privacy Policy.
- If a tool gives an unexpected result, try the same check on a different page first — the audit reports what it finds on the page you enter.
- For how the site works and what each tool does, see the About page or the guides on each tool page.
