Metaspry

One-click meta-tag audit and social preview for any page. Local-first, no account, no telemetry. OG, robots, sitemap, JSON-LD.

The one-click meta-tag analyzer for modern websites. See how your page renders across major social and search platforms - locally, with no account, no telemetry. Open any page, click the toolbar icon, and the side panel shows: • TAGS - every element on the page, categorized for quick scanning. Search, copy, and pin tags across pages. • PREVIEWS - exact mockups of how your share card renders on the major social and search platforms. Rendered from the page's own tags, with documented fallback chains. Full platform list at metaspry.com/docs/previews. • AUDIT - weighted 0-100 score across 12+ rules covering required, recommended, and best-practice meta-tag hygiene. Includes live image dimension checking. • SITE - robots.txt, sitemap.xml (recursive sitemap-index expansion, 7 fallback paths), and llms.txt fetched and parsed from the page's host. WHY METASPRY Free forever. No account, no signup, no card. Local-first. The audit, parsing, and previews all run inside your browser. The only network calls are reading the site files of the page you audit (robots, sitemap, llms.txt). No first-party servers. Privacy-respecting. No telemetry, no analytics, no tracking. Works offline once a page is cached. Open roadmap on metaspry.com. Built for engineers, SEO specialists, content teams, and indie builders.
