Hreflang Checker

Check any page's hreflang tags for valid language codes, an x-default fallback, a self-reference, and duplicates — then, for every declared target, confirm it actually links back. Most free hreflang checkers only validate the tag's syntax; this one follows every declared target and checks the reciprocal return tag too.
