Live Social Preview & Open Graph Debugger
Test any URL to verify how your link cards render across X (Twitter), Discord, Slack, and LinkedIn. Inspect tags, catch truncation, and verify 1200×630 safe zones.
How to Test & Fix Open Graph Cards
When links are shared on social platforms, high-converting Open Graph share cards command user attention. If your meta tags are missing, misconfigured, or lack summary_large_image, platforms fallback to plain text links or cropped square thumbnails.
Frequently Asked Questions
Why was the official Twitter Card Validator deprecated?
Twitter (X) deprecated its standalone online Card Validator tool in 2022 and moved card rendering directly into the Tweet Composer preview. Because the native composer frequently caches previews or requires a signed-in account, developers needed an instant, independent validator to test link card tags.
What is the recommended size for Open Graph and Twitter cards?
The universal standard is 1200×630 pixels (1.91:1 aspect ratio). Keep all vital typography, logos, and focal elements centered within a 1080×560 pixel safe zone so that mobile crop variations on Twitter, Discord, and LinkedIn do not truncate critical text.
How do I force Twitter/X and Discord to refresh a cached card?
Social platforms cache OG images aggressively. To test updates immediately, append a cache-busting query parameter to your test link (e.g., https://yourdomain.com?v=2) or use the Facebook Sharing Debugger and LinkedIn Post Inspector to purge Edge CDNs.
Which Twitter Card type should I use?
For modern websites, always specify <meta name="twitter:card" content="summary_large_image">. The standard 'summary' card only displays a tiny square thumbnail, whereas 'summary_large_image' displays the full-width 1200×630 artwork that captures user attention in fast-scrolling feeds.
