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 Facebook / Twitter / LinkedIn / Slack rendering side-by-side and screenshot the one that breaks.
Built by one engineer
The audit I wish I'd had at every job.
Hi, I'm Paul - a software engineer who got tired of shipping pages with broken OG cards, missing Twitter previews, and silent crawler issues. Metaspry runs entirely in your browser, takes one click, and shows you exactly what Google, Twitter, LinkedIn, and Slack see when they crawl your page.
