// FAQ
What can this tool do?

Extract alternate hreflang links from a URL and check duplicates, relative URLs, and x-default.

How is the input handled?

URL checks use the TOOLPOOL fetch API to retrieve the target page. This does not send local files or unrelated browser data.

Can I share the result?

After running a check, you can copy a share link. The shared URL may include URL parameters needed to run the same check again.
