Canonical & Hreflang Auditor
Check a page's canonical tag and its whole hreflang cluster — self-references, duplicates, invalid codes, missing x-default.

This tool processes data online
It fetches the public HTML of the page you enter — the same source any browser receives when visiting it. The audit runs entirely in your browser.
- No logs, nothing stored. What you submit is processed in memory and discarded — never saved, never used for marketing, never shared.
- Public data only. The tool fetches what anyone can already see in a browser — no logins, no private pages, no bypassing paywalls.
- Fair use. Ten checks per minute per visitor — each one is a real network request on our side.
