Preview how a link looks when shared

Liveby Superpowers share preview

Shows how a link will look when shared on WhatsApp, LinkedIn, X and Facebook, and what to fix.

Reads the page's Open Graph and Twitter tags, loads the share image to check its size, shape and weight against each platform's rules, and draws the four previews side by side in one image, with titles and descriptions cut where each card cuts them. Lists problems such as a missing or broken image, an image too small or too heavy, a shape that gets cropped, or a missing twitter:card. The drawings approximate each app's card.
