Launched on Cloudflare
Shipped CardScope on Cloudflare. Fetch at the edge, parse the tags in memory, then forget the page. That privacy note is the product, not a footer.
CardScope
A small tool that fetches a URL at the edge, reads the Open Graph and Twitter tags, and shows how the unfurl will look on X, LinkedIn, Slack, Discord, and iMessage — plus a short checklist of what to fix. Free to use, with a $19 Pro unlock. No account. Page HTML is not stored.

Early build notes
Started as a scratch tool because every client reads a different set of meta tags. Slack wants Open Graph; Discord leans on twitter:card; iMessage falls apart without an image. One paste, five shells.

Kept the scope small
Paste a URL, see the unfurl, fix the tags. No accounts, no stored HTML, no extra product around it.
