Why this matters

When someone shares your link in Slack or on X, the preview card is your first impression. A missing or ugly og:image means a blank or broken-looking card — and fewer clicks. This tool shows you what everyone else sees, and Cardsmith can generate the image if you don't have one. See the framework guides →
