Metaspry

One-click meta-tag audit & social preview — OG, Twitter, robots, sitemap, JSON-LD. Optional sign-in syncs scans to your account.

The one-click meta-tag scanner for modern websites. See how your page renders across the major social and search platforms - locally, with no account and no telemetry. Open any page, click the toolbar icon, choose "Scan this page", and the side panel shows six tabs: • TAGS - every <meta> element on the page, categorized for quick scanning. Search, copy, pin tags across pages, export JSON or CSV. • PREVIEWS - mockups of how your share card renders on the major social and search platforms, built from the page's own tags with documented fallback chains. Full list at metaspry.com/docs/previews. • AUDIT - a weighted 0-100 score across 19 rules covering required, recommended and best-practice meta-tag hygiene, including live image dimension checking and the X-Robots-Tag header. • SITE - robots.txt, sitemap.xml (sitemap-index expansion, 7 fallback paths) and llms.txt, fetched and parsed from the page's host. • AI - AI-readiness checks: indexability, headings, structured data, author and date, AI crawler access, llms.txt. • COMPARE - the current page against any URL, tag by tag, with both scores. Keyboard shortcuts 1-6, /, r and ? (single-key shortcuts can be turned off in Settings > Preferences, where you also pick side panel or popup). WHY METASPRY - Free. Every tab works with no account, no signup and no card. - Local-first. Parsing, the audit and the previews run inside your browser. The only network calls are the site files of the page you scan (robots.txt, sitemap, llms.txt), the page itself and its share image, and a URL you choose to compare. - Optional sign-in saves your scans to your Metaspry account (same login as the web app). Free lists your 10 most recent cloud scans; Pro lists 50 and keeps up to 20 earlier versions of a page when it changes. A re-scan shows when you last scanned the page, with a link to what changed. - No telemetry, no analytics, no tracking. - Open roadmap on metaspry.com. Built for engineers, SEO specialists, content teams and indie builders. Docs and roadmap: https://metaspry.com Bug reports: https://github.com/metaspry/metaspry/issues
