The meta-tag analyzer for modern websites.
Audit OG cards, social previews, robots.txt, sitemaps, and llms.txt for any page - in one click. On Pro, the cloud app re-checks your key pages every day and sends an email and Slack alert when a page's score drops below your threshold or a required tag like og:image breaks. Built for engineers and content teams who care what crawlers actually see.

Six tabs in the extension. Your whole site in the web app.
In the extension
Seven social previews
Facebook, X, LinkedIn, Discord, Slack, Google SERP and iMessage cards - all from one scan.
Scored audit, and what changed
19 rules, one 0-100 score. Signed in, "Last scan" opens what changed since then in the web app (1.0.27 and later).
Compare with another page
Put this page's tags beside any other URL - a competitor, staging, or the old version - and see what differs.
Settings that stay out of the way
Side panel or popup, single-key shortcuts on or off (1.0.27 and later), and Pro scoring rules synced with your account.
In the web app
Dashboard
Scan any URL, continue a sitemap run where you stopped, and see which monitored pages need attention.
History, ready to compare
Scans from the extension and the web app in one list. Tick two and press Compare selected.
What changed between two scans
Tags, rule results and AI-readiness side by side, summed up in one line. Swap sides or copy it as Markdown.
A fix for every warning
Each failing or warning rule says how to fix it, links to its docs and can become a task.
Bulk runs with top issues
Audit up to 1,000 URLs or a sitemap per run, then see which issues hit the most pages.
Daily monitoring (Pro)
Monitored URLs are re-scanned every day, with email and Slack alerts when a score drops below your threshold or a required tag fails.
How it works
Three steps. Zero friction.
Inspect free in under a minute. Sign in for cloud history, and go Pro for daily monitoring.
Metaspry vs. doing it yourself
Manual means View Source, scattered free validators, and a spreadsheet to track it - with no history and no alerts. Metaspry puts it in one place: scored, saved, bulk, monitored, shareable.

When you'd reach for it
Before publishing
Catch a missing og:image, a truncated description, or a stale canonical before the post goes live.
Auditing client sites
Run a one-pass audit, export the JSON, hand it to the client with a concrete fix list.
Sharing previews
Pull up the social and search renderings side-by-side and screenshot the one that breaks.
Monitoring production
Add your key URLs to Monitor (Pro) and get an email and Slack alert when a page's score drops below your threshold (80 or 50) or a required tag like og:image breaks on the daily re-check - with the rules that changed.
Auditing at scale with a team
Bulk-audit hundreds of URLs from a sitemap, track fixes on a shared board, and give the whole team one workspace with roles.
