Hreflang Generator
Generate hreflang alternate link tags.
Add hreflang language/region codes with absolute URLs to produce link rel="alternate" hreflang tags, optionally including x-default from the first valid row.
Limitations
Hreflang requires reciprocal tags on every listed version, correct ISO codes and URLs that return 200. This generator only formats markup — it does not crawl pairs, check sitemap hreflang entries or fix conflicting canonicals.

FAQ
Each localized URL in a set should reference all siblings, including itself, with matching hreflang values. One-way tags are a common implementation mistake.
It suggests a fallback URL when no listed language matches the user. Optional but useful for global homepages or language pickers — pick the URL deliberately.
Hreflang helps search engines show the right regional URL; it is not a substitute for unique content, proper canonicals or removing true duplicates.
