Hreflang Tags Testing Tool review (2026): is it any good?
Free validator that checks hreflang tags across a list or sitemap
Hreflang Tags Testing Tool report card
Very good · out of 4.0 · graded Oct 23, 2026
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.
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 Hreflang Tags Testing Tool 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
Why Hreflang Tags Testing Tool gets a 3.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree, with no paid plan to buy. Signing in adds test history and an API key at no cost.
- AFree plan and trialFree 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.
- DFeaturesOne 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.
- BEase of useNo 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.
- BPlatforms and integrationsWeb only, with a free REST API for signed-in users to submit URL lists or sitemaps and fetch results. No other integrations on record.
