Why did my URL return an error?

Some sites block previews via robots noarchive directives, require authentication, or time out before the fetch completes. Verify the page is publicly accessible and does not disable crawling for metadata bots.

How long are results cached?

Responses are cached for up to 24 hours at the edge so repeat requests stay fast. Re-run the fetch after updating your page to refresh the cache.

Does the tool execute scripts or use my cookies?

No. The fetch runs server-side with a static user agent, avoids executing client JavaScript, and strips cookies. Only sanitized metadata fields are returned to the browser.

Open Graph & Metadata Preview

See Open Graph, Twitter Card, and rich link previews before publishing.

Understand exactly what metadata platforms like Facebook, X, Slack, and iMessage will extract before you share your link. The preview respects robots policies, sanitizes responses, and surfaces every relevant tag in one workspace.

Key points

Verify how links unfurl

Fetch target pages through a sanitized metascraper endpoint that follows redirects, normalizes canonical URLs, and surfaces the fields social networks rely on.

Inspect every metadata layer

Compare Open Graph tags, Twitter Card attributes, and JSON-LD snippets side-by-side to confirm messaging, imagery, and schema coverage.

Share reproducible states

Stateful share links encode the requested URL and active tab so collaborators can review the same metadata snapshot instantly.

Paste a URL above to see its structured metadata preview.

How to use this tool

Step 1
Paste the page URL
Drop in a fully qualified link (http or https). The tool auto-detects missing protocols and respects robots directives before fetching.
Step 2
Review metadata across tabs
Switch between the summary, Open Graph, Twitter, and JSON-LD views to validate copy, imagery, and structured data payloads.
Step 3
Iterate and re-run
Update your source page, wait for it to deploy, then refetch to confirm the new metadata. Share the link with teammates for quick sign-off.
