Intlayer i18n Scanner 作者： aymericzip

Instantly see how any website handles internationalization: which framework and i18n library it uses, which locales it serves, and whether its multilingual SEO tags are correct. Run a full i18n/SEO audit in one click.

Detected technologies

Framework (Next.js, Nuxt, Astro, SvelteKit, Angular, Vue, Qwik, React, Gatsby, Remix, WordPress…) and i18n library (Intlayer, i18next, Vue I18n, @nuxtjs/i18n, Weglot, WPML, Polylang…), with version and the evidence behind each detection.

Locales

Locales discovered from the lang attribute, hreflang and og:locale tags, URL locale prefix, and locale cookies or storage entries.

i18n SEO tags

Checks html lang / dir, canonical, hreflang, x-default, og:locale, and the ratio of localized internal links.

Page navigator

Browse the pages of the site straight from its sitemap.

Full audit (optional)

Click "Run full audit" to stream a complete i18n/SEO audit from the Intlayer scanner (the same one as https://intlayer.org/i18n-seo-scanner), with a live score and every check explained. Only then is the page URL sent to the Intlayer server.

Privacy-friendly: the add-on only reads the current tab when you open the popup (activeTab). There's no background tracking, no broad host access and no account needed.
