Social Card Checker
Paste a link and see the card X, LinkedIn and Slack will build from it — including whether the image URL actually serves an image.
Cards are cached hard by every platform. After fixing your tags you have to make the platform fetch again — through its own debugger, or by sharing the URL fresh — or you will keep seeing the old card while new visitors see the new one.
This tool requests pages as itself rather than impersonating a platform crawler, so what you see is what an ordinary client sees. It is not affiliated with X, LinkedIn, Slack or Meta.
