SharePeek — Open Graph & Social Card Preview

See your share card before you ship it. SharePeek shows how the page in your current tab will look when someone posts the link, and flags the Open Graph and Twitter Card problems that would break the preview — six card layouts, side by side. Works on localhost and staging. The public debuggers only accept live URLs. SharePeek reads the tab you're on, so you can check a card while you're still building the page. What you get • Six side-by-side previews — the large image card, the small summary card, the chat unfurl, the messaging-app strip • A tag checklist with specifics: missing og:image, non-https image URLs, an image that 404s, a title that's too long, no twitter:card, missing og:image:width/height, no canonical, and more — each with the one-line fix • "Copy report" — a plain-text summary to drop in a PR or ticket Private by design No account. No tracking. No network calls. SharePeek only reads the tab you click it on, only when you click it, and nothing ever leaves your browser. It asks for activeTab and scripting — nothing else. Free.
