CardScope

What is CardScope?

Paste any URL and instantly see how its link card is likely to render on X, LinkedIn, Slack, Discord, and iMessage — plus a concrete fix checklist. CardScope reads Open Graph and Twitter metadata, builds five client previews, and turns missing or conflicting tags into fixes you can act on. Free: 3 checks/day per location, no account. Privacy-first: page HTML is parsed in memory and not stored. Pro is $19 one-time for unlimited checks, shareable reports, and PNG export.
