Social Card Preview - Open Graph & Twitter

Open Graph preview for any link. See how it looks shared on X, LinkedIn, Facebook, Slack and Discord, plus tag validation.

Social Card Preview is the fastest Open Graph preview and validator for Chrome. See exactly how any link will look when it is shared on X, LinkedIn, Facebook, Slack, and Discord, then fix the missing tags before you publish. One click turns your current tab into a live Open Graph preview with a clear pass or fail checklist. 🚀 Most link previews go wrong silently. A truncated title here, a missing image there, a stale cache on one network. By the time you notice, the post is already live and the bad card is already shared. Social Card Preview catches all of that in seconds, on the page you are already looking at, with no login and no copy and paste. 🚀 WHY PEOPLE LOVE THIS OPEN GRAPH PREVIEW Every other tool shows you raw tags and leaves you to guess. This Open Graph preview renders five real platform cards side by side, each with the correct crop and the correct title and description length, so what you see is what your audience will see. When something is missing, you get the exact meta tag to paste, not a vague warning. It is a social share preview and a fixer in one. ⚡ EVERYTHING IN THE FREE PLAN ✓ Live Open Graph preview of your current tab, unlimited, no login ✓ Five accurate platform mockups: X, LinkedIn, Facebook, Slack, Discord ✓ Per platform crop and truncation that match the real card ✓ Full Open Graph and Twitter Card preview with a pass or fail checklist ✓ Plain language fix for every missing or malformed tag ✓ One click copy of a ready to paste meta tag block ✓ Resolved title, description, image, canonical, and site name ✓ Cache busting so a stale image never fools your social share preview ✓ A health grade from A to F with the exact issues to fix 🔓 WHAT PRO UNLOCKS ✦ Preview any URL without opening it. Paste a link and our server fetches and parses it for you, so you can audit a competitor page or a page you have not published yet. ✦ AI written card copy. Generate an optimized title and description tuned for clicks, then copy the meta tags in one step. ✦ Bulk check a list of URLs and export the results, so a whole site migration becomes one Open Graph preview pass instead of fifty. ✦ Open Graph image ratio validator that flags crops that will break on a 1.91 to 1 card. ✦ History of the last 100 pages you checked. 🎯 WHO IT IS FOR Marketers shipping campaigns, content writers publishing posts, SEO specialists auditing pages, developers wiring up meta tags, and social media managers who are tired of the broken Twitter Card validator and the clunky Facebook debugger. If you publish links, this Open Graph preview saves you from a bad first impression. 🛠️ HOW IT WORKS 1. Open any page you want to share. 2. Click the Social Card Preview icon to run an instant Open Graph preview of the current tab. 3. Switch between the X, LinkedIn, Facebook, Slack, and Discord tabs to see each real card. 4. Read the validation checklist and copy any fix you need. 5.

The Open Graph preview of the page you are on uses no server at all. Only the Pro pasted URL fetch and the AI copy feature contact our server, and only with the URL you typed. No browsing history, no page content from other tabs, ever. 📊 ACCURACY AND PERFORMANCE The preview opens in well under a second because it reads the live page instead of re fetching it. Each platform mockup uses a maintained spec table: X large image cards use a 1.91 to 1 crop and hide the description, LinkedIn truncates the title near 115 characters and drops the description, Facebook shows the domain in capitals, Slack shows the favicon and a fuller description, and Discord shows the full og:description at the natural image ratio. A wrong preview is worse than none, so accuracy is the whole point. 🆚 WHY THIS OVER THE ALTERNATIVES ✓ Five platforms in one view instead of a single card ✓ Tells you exactly which tag is missing and how to fix it, not just the raw values ✓ A real social share preview that works on localhost, staging, and logged in pages ✓ Replaces the retired Twitter Card validator and the slow Facebook sharing debugger ✓ Minimal permissions and no access to all your sites 🛡️ SECURITY Built on Manifest V3 with no remote code. The extension requests only storage, activeTab, and scripting, plus a single connection to our own domain for license checks and the optional Pro features. It never requests access to all your websites. ❓ FREQUENTLY ASKED QUESTIONS Q: Is the Open Graph preview really free? A: Yes. Previewing and validating your current tab is unlimited and free with no account. Pro adds pasted URL preview, AI copy, and bulk checks. Q: Does it work as a Twitter Card preview too? A: Yes. It reads twitter:card, twitter:title, twitter:image, and the rest, then renders the X card exactly as it will appear, including the summary versus large image difference. Q: Can I use it as an open graph validator on localhost or staging? A: Yes. Because it reads the live page in your browser, it works on localhost, staging, and pages behind a login that a server side og tag checker cannot reach. Q: Will it show a stale image? A: No. The social share preview busts the image cache by default, so you always see the current og:image, not an old one. Q: Does it send my data anywhere? A: The current page Open Graph preview is fully local. Only the optional Pro pasted URL fetch and AI copy contact our server, using just the URL you provide. Q: Which platforms are supported? A: X, LinkedIn, Facebook, Slack, and Discord, each with its own crop, title length, and description rules. 🚀 GET STARTED Install Social Card Preview, open any page, and click the icon for an instant Open Graph preview.
