See your link on 5 platforms at once, before you hit publish
One click shows how the current page (or any pasted URL) looks shared on X, LinkedIn, Facebook, Slack, and Discord, then tells you exactly which Open Graph or Twitter tag is missing and the meta to paste.
Free current-tab preview and validation. No login. Your page never leaves your browser.
All five in one view
Every platform crops your card differently. We show you each one.
X uses a 1.91:1 large card. LinkedIn shows the title only and truncates around 115 characters. Discord shows your full description. One look tells you if your card holds up everywhere.
Why people pin it
A share preview that actually fixes the problem
Most checkers show one platform and stop there. This one shows all five, finds the broken tag, and hands you the exact line to paste.
Five platforms, one view
X, LinkedIn, Facebook, Slack, and Discord side by side, each with its real crop and truncation, so you catch the one that looks wrong.
Tells you the exact missing tag
A red, amber, green checklist flags every missing or weak Open Graph and Twitter tag, with the exact <meta> line ready to copy.
Works on localhost and staging
It reads the live DOM of the current tab, so it works on localhost, staging, and logged-in pages that a remote crawler can never reach.
Preview any pasted URL Pro
Drop in any link and the server fetches and parses its tags for you, no CORS limits, no opening the page yourself.
AI-written card copy Pro
Generate an optimized title and description tuned to each platform's length limits, then paste the meta straight into your page.
Private by default
The current-page read happens entirely in your browser and never hits a server. Only the optional Pro URL fetch sends data, and only the URL you typed.
How it works
From "looks broken" to "looks great" in three steps
No setup, no account. Open the page you want to share and click the icon.
Open any page
Click the Social Card Preview icon on the page you are about to share. It reads the title, description, image, canonical, and every og: and twitter: tag.
See all five cards
Live mockups render exactly how X, LinkedIn, Facebook, Slack, and Discord will crop and truncate your card, side by side.
Fix what's missing
The validation checklist flags the missing tag and gives you the precise meta snippet. Paste it, reload, and the preview turns green.

FAQ
Questions, answered
Is the current-page preview really free?expand_more
Yes. Previewing the tab you are on and validating its tags is free forever, with no account. The Pro plan only adds pasted-URL fetch, AI copy, bulk checks, and history.
Does my page get sent anywhere?expand_more
No. The current-page read uses Chrome's activeTab and scripting to parse the tags locally in your browser. Nothing about the page is transmitted. Only the optional Pro pasted-URL fetch sends a request, and it sends only the single URL you typed.
Why is this better than the old Twitter Card validator?expand_more
X retired its card validator and Facebook's sharing debugger is slow and one platform at a time. Social Card Preview shows all five platforms at once, works on pages a remote crawler cannot reach, and gives you the exact fix snippet inline.
Does it work on localhost and staging?expand_more
Yes. Because it reads the live DOM of the tab you are on, it works on localhost, password-protected staging, and logged-in pages, where URL-based validators fail.
How do I cancel Pro?expand_more
Cancel anytime from the Stripe billing portal linked in your receipt. Your Pro features stay active until the end of the period you already paid for.
