Generate and validate hreflang tags for multilingual SEO in HTML, XML sitemap, and HTTP header formats.

HTML <head> snippet
<link rel="alternate" hreflang="en" href="https://example.com/en/" />
<link rel="alternate" hreflang="fr" href="https://example.com/fr/" />
<link rel="alternate" hreflang="de" href="https://example.com/de/" />
<link rel="alternate" hreflang="x-default" href="https://example.com/en/" />
How to use: Paste these tags inside the <head> element of every localised page — each page must self-reference its own locale and include all siblings.
