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. - **Value for money: A.** Free, with no paid plan to buy. Signing in adds test history and an API key at no cost. - **Free plan and trial: A.** Free 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. - **Features: D.** One 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 use: B.** No 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 integrations: B.** Web only, with a free REST API for signed-in users to submit URL lists or sitemaps and fetch results. No other integrations on record. These are ToolGPA's own grades. Graded from this listing, whose facts were read from hreflang.org's own pages on 23 October 2026.
