Open Graph Preview

Open Graph Preview reads a page's og: and twitter: meta tags and renders an approximation of the card that appears when the link is shared, falling back to the page's regular title and description if no social tags are set at all.

Use this before sharing a link somewhere it matters, when a shared link is showing the wrong image or a blank preview, or when checking that a new page actually has social tags configured rather than assuming a template covers it.

This is an approximation built from the same tags every platform reads, but each platform (X, Facebook, LinkedIn, Slack, and others) renders its own card slightly differently and caches whatever it first saw, sometimes for a long time after the tags themselves change.
