Free tools
Set the tags. Pull the proof.
18 tools for the parts of SEO that are just markup done carefully. They run in your browser, so there is no account, no queue, and nothing of yours on our server: closing the tab is the whole privacy policy.

Why there is no sign-up
- Nothing is stored
- No database row, no session, no cookie. These pages never post to the server.
- Nothing is queued
- No account and no rate limit, because there is no request to limit.
- Reload is a reset
- What you type lives in the page. Leaving clears it because there was nowhere else for it to be.
The audited side of AmPuH SEO Intelligence Next does need an account, because it fetches your pages, talks to Google on your behalf and keeps a history you can compare against. These 18 do none of that, so they ask for nothing. If you want the fetched version of what these tools infer, the public preview runs the real audit on one page without an account.
