Four are live. Two are being built. Nothing here requires an account, and nothing sends your copy to a server.
Type a title and description per language and see the exact pixel width, the truncation point and how each locale compares to your English baseline.
Solves: the title that fits in English and gets cut in German.
One URL pattern, a list of markets, and you get a reciprocal head block plus matching sitemap XML. Locale codes are validated, including the deprecated ones.
Solves: the one-way declaration that Google silently ignores.
Paste a sitemap with xhtml:link alternates and every URL is checked at once — codes, duplicates, self-reference, x-default, and whether each declaration is returned.
Solves: you generated the tags but cannot tell whether the other pages actually link back.
Drop a crawler export and every row is measured at once — grouped by market, worst first, duplicate titles flagged, downloadable as CSV.
Solves: checking 200 URLs by hand, which nobody does twice.
Compare the keyword you translated against what people actually search in that market. Literal translations routinely have a fraction of the volume.
Solves: ranking #1 for a phrase nobody types.
Count CJK characters as full-width, catch half-width punctuation mixed into Japanese or Chinese copy, and get a length budget that matches how the language actually renders.
Solves: character counts that mean nothing in CJK.
