URL Metadata Fetcher
Preview how any URL looks when shared on Facebook, Twitter/X and LinkedIn.
URL
Free · 10 lookups per browser per day, 100 per network. URL is fetched server-side (browsers can't due to CORS); nothing is stored beyond a rate-limit counter.
About this tool
Paste any public URL to see the exact preview card Facebook, Twitter/X and LinkedIn will render when someone shares it. The tool extracts every og:* and twitter:* meta tag, plus canonical, language, favicon, page title and description - each with a one-click Copy button so you can lift values straight into a report or a fix. Unlike every other tool on this site, this one uses a server-side proxy (a small PHP endpoint on suparnpatra.com) because browsers can't fetch cross-origin URLs directly. Rate-limited to 10 lookups per browser per day (and 100 per network) to keep the endpoint cheap and impossible to abuse. Nothing is stored beyond a rolling quota counter.
FAQs
Why isn't this in-browser like the other tools?
The browser same-origin policy blocks cross-origin fetches, so we can't read arbitrary URLs from JavaScript. LinkedIn's Post Inspector and every other preview tool works the same way: a small server-side fetcher.
What are the limits?
10 lookups per browser fingerprint per day, and 100 per IP address per day. Both counters reset at 00:00 UTC. Enough for personal use; not enough for scraping.
Do you store the URLs I look up?
No. The server keeps a per-IP and per-(IP+User-Agent) counter for quota, but the URLs themselves aren't logged.
Which meta tags are surfaced?
Page title, meta description, canonical, lang, favicon, all og:* (title/description/image/url/type/site_name/locale) and all twitter:* (card/title/description/image/site/creator).
