What it is, who it suits, its grades and the ten things to know first

3.0

GPA, above 73 of the 83 other technical SEO tools we grade

The Hreflang Tags Testing Tool on hreflang.org is a free web-based validator for multilingual and multi-regional sites. Paste a list of URLs or an XML sitemap and it crawls the pages, checking return tags, canonicals, language and region codes, x-default and the status of every hreflang URL. It is a one-person hobby project, with a free API for signed-in users.

To get you started, here are 8 things to know about Hreflang Tags Testing Tool, taken from its own pages and our grades.

No rating on record, and nothing to sign up for: paste URLs or a sitemap and run the test.

The report card

Best for checking hreflang tags on a multilingual site

The Hreflang Tags Testing Tool crawls a list of URLs or a sitemap and checks return tags, canonicals, language codes, x-default and the status of every hreflang URL, for free. But it's a one-person hobby project, sign-in works only through LinkedIn, hreflang inside XML sitemaps isn't analyzed, and its own pages disagree about the limits.

ToolGPA report cardHreflang Tags Testing ToolGraded Oct 23, 2026
SubjectGradeComment
Value for moneyAFree, with no paid plan to buy. Signing in adds test history and an API key at no cost.
Free plan and trialAFree outright. Up to 30 URLs a test without an account, more with a free LinkedIn sign-in, and the free API allows 50 URLs a test and 10 tests a day.
FeaturesDOne narrow job: hreflang checks on a URL list or sitemap, covering return tags, codes, canonicals, x-default and status codes, with Excel export. It doesn't read hreflang declared inside XML sitemaps, and sitemap index files aren't supported.
Ease of useBNo rating on record, and nothing to sign up for: paste URLs or a sitemap and run the test. Signing in is optional, for higher limits.
Platforms and integrationsBWeb only, with a free REST API for signed-in users to submit URL lists or sitemaps and fetch results. No other integrations on record.
Grade point averageVery good, out of 4.03.0

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who Hreflang Tags Testing Tool is for

  • Fits if you're checking a multilingual site's hreflang setup before launch
  • Works for tracking down missing return tag errors from Search Console

Who it is not for

  • Skip it if your hreflang lives in XML sitemaps or you use a sitemap index, as neither is read
  • Not for you if you don't have LinkedIn, the only way to sign in for higher limits and the API
  • Tight if your site is large: 30 URLs a test without signing in, and anything past the signed-in limit arranged by email
  • Watch out: its pages give different signed-in limits (100 or 250 URLs a test), and the API docs mention a premium tier with no price
  • Watch out: the maker describes it as a hobby project run by one person

Good to know
