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.
Cloudflare on cardscope.dev is new — the zone only went up around Sep 19. That day: 208 unique visitors and 541 page views. Sep 20: 137 uniques and 185 views. Daily uniques are not fully deduped across days, so I am not rolling them into a weekly total. Shipped the product plus an SEO guide. Product Hunt launch is set for Tue Sep 22, 12:01 AM PDT. Submitted to Ignlab Launch (pending). Tried a few other free directories; some blocked the listing or wanted a branded email. Weekday one-action marketing continues. Two Pro unlocks via Stripe Checkout: one at $19, one at $0 on a founder test promo.
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.
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.
