See how your link unfurls on every social platform
Paste any URL to preview how it will appear on Facebook, Twitter, LinkedIn, and Slack — and get a list of missing Open Graph tags before you share.
How it works
Step 1
Paste a URL
Enter any public page URL — your homepage, a blog post, a product page.
Step 2
We fetch and probe
Our server fetches the HTML, extracts all Open Graph and Twitter Card tags, then HEAD-probes the og:image to confirm it's reachable and checks its dimensions.
Step 3
See previews + diagnosis
You get live previews of how the card will render on Facebook, Twitter, LinkedIn, and Slack, plus warnings for missing tags and image issues.

FAQ
- Why is my og:image not appearing in the previews?
- Three common causes: (1) the image is not served over HTTPS — Facebook refuses non-HTTPS images; (2) the image is too small — most platforms need at least 200×200 and look best at 1200×630; (3) the page has og:image set but the image URL returns 404 — re-paste the URL in a browser to confirm. The image probe section in the result will tell you which it is.
- Should I set Open Graph, Twitter Card, or both?
- Both. Open Graph is read by Facebook, LinkedIn, Slack, Discord, iMessage, and most other platforms. Twitter Card (X) prefers twitter:card but falls back to og:* if Twitter Card tags are missing. The minimum safe set is the six og:* tags plus twitter:card.
- How often do social platforms re-scrape my page?
- Facebook re-scrapes every 30 days or when you hit the Sharing Debugger; Twitter re-scrapes within minutes of a new share but caches the result for 7 days; LinkedIn is the slowest, often a few days. If you change og:* tags, use the platform debuggers to force a re-scrape.
