Test a URL in the Open Graph Preview Tool
Use LinkPeek as a free Open Graph preview tool when you need to see the actual card experience, not only a list of tags. Paste a URL and inspect the title, description, image, canonical URL, Twitter Card fallback, and platform-specific rendering across WhatsApp, LinkedIn, X, Slack, Discord, and Instagram. Developers can also test localhost URLs before deployment, which makes Open Graph QA part of the normal build workflow instead of a last-minute production check.
Check the tags that control every social card
Open Graph tags decide how most social apps summarize your page. A small mistake in og:title, og:description, og:image, or og:url can produce a blank card, stale image, or misleading preview. LinkPeek turns those tags into visual previews so the metadata can be evaluated like a real UI surface.
- Validate og:title, og:description, og:image, og:url, og:type, and og:site_name
- Compare Open Graph output with Twitter Card fallbacks and app-specific layouts
- Catch relative image paths, missing HTTPS, weak descriptions, and bad canonical URLs
Built for developers before and after deployment
Many Open Graph problems are introduced while a page is still being built. LinkPeek supports local development workflows, production URLs, and cache-busted retests, so teams can catch metadata problems before platforms cache the wrong version.
- Test localhost previews without deploying only to inspect a card
- Retest production pages after metadata changes or CMS updates
- Use the audit output to hand clear fixes to the developer who owns the page head
Preview more than one generic card
A technically valid Open Graph setup can still look wrong on a specific platform. WhatsApp may crop the image tightly, LinkedIn may use a stale image, Slack may emphasize site name, and X may prefer Twitter Card tags. LinkPeek shows these differences in one workflow.
- Review WhatsApp, LinkedIn, X, Slack, Discord, and Instagram-style previews
- Check whether the same image and copy survive different card dimensions
- Use platform-specific warnings instead of guessing from raw HTML
How to use this open graph preview tool

- 2Run the scan and let LinkPeek fetch the metadata.
- 3Review the visual cards for WhatsApp, LinkedIn, X, Slack, Discord, and Instagram.
- 4Fix missing or weak Open Graph and Twitter Card tags in your app or CMS.
- 5Retest the canonical URL and a cache-busted URL before sharing publicly.
Common issues this page helps debug
The OG image URL is relative
Social crawlers need an absolute HTTPS image URL. Replace /og.png with a full URL such as https://example.com/og.png.
The title looks fine in HTML but bad in cards
Long titles can wrap or truncate differently across apps. Preview the card visually and write a shorter social-specific title when needed.
The page depends on client-side metadata
Social crawlers usually read server HTML. If your framework injects tags only after JavaScript runs, platforms may never see them.
Platforms show stale metadata
WhatsApp, LinkedIn, Slack, and X cache link previews. After fixing tags, retest with the canonical URL and a versioned cache-busting URL.
Frequently asked questions
What is an Open Graph preview tool?
An Open Graph preview tool checks the metadata social apps use to generate link cards, including title, description, image, canonical URL, and card type.
Can LinkPeek preview OG tags before deployment?
Yes. LinkPeek supports localhost preview workflows so developers can test Open Graph tags before a public deployment or ngrok tunnel.
Does an Open Graph preview tool clear social caches?
No checker can directly clear every platform cache. LinkPeek helps verify the fixed metadata and shows when a cache-busted URL should be tested.
Should I include Twitter Card tags with Open Graph tags?
Yes. X can use Open Graph fallbacks, but twitter:card is still important for controlling card style and large image previews.
