See your share card before you ship it
SharePeek is a free Chrome extension. Click it on any page — includinglocalhost and staging — and it shows how the link renders on X, Facebook, LinkedIn, Slack, Discord and WhatsApp, plus a checklist of the Open Graph and Twitter Card problems that would break it.

Why it's different
- Works on localhost. The Facebook and X debuggers only accept public URLs. SharePeek reads the tab you're on, so you catch a broken card while you're still building the page.
- Specific fixes. Not "your OG is bad" — it tells youog:image is not https, image 404s, title too long,no twitter:card, each with the one-line fix.
- Private by design. No account, no tracking, no network calls. It reads only the tab you click it on, and nothing leaves your browser. Permissions:
activeTabandscripting, nothing else.
What you get
- Six side-by-side previews — the large image card, the small summary card, Slack/Discord unfurls, the WhatsApp strip
- A tag checklist: missing
og:image, non-https image URLs, an image that 404s, a title that's too long, notwitter:card, missingog:image:width/height, no canonical — with fixes - Copy report — a plain-text summary to drop in a PR or ticket
