Cách dùng

  1. 1 Paste any public URL.
  2. 2 Press Test (or Enter). We fetch the page and parse its og:* and twitter:* meta tags.
  3. 3 Preview how the link looks on Facebook, Twitter / X, LinkedIn, and Slack — with validation warnings.

Vì sao dùng công cụ này

  • Four platform previews side-by-side — pixel-tuned to match real share cards.
  • Validation warnings catch missing tags, oversized titles, and HTTP image URLs.
  • See the raw og:* and twitter:* tags exactly as the platforms read them.
  • Cached for 10 minutes, rate-limited to prevent abuse.

Câu hỏi thường gặp

Does Facebook see what I see here?

Almost — Facebook caches share cards for ~7 days. After updating your OG tags, run Facebook's Sharing Debugger to force a recrawl.

Why is the preview empty for some URLs?

Some sites render OG tags via client-side JavaScript (e.g. Next.js without SSR). We only see the initial HTML, so dynamic tags will be missing.

Is this safe to use on private URLs?

We block localhost, private IP ranges, and internal hostnames. But we still fetch the page from our server, so don't paste URLs that require authentication.

What rate limit applies?

30 requests per minute per IP. Cached results don't count against your limit.

Open Graph Preview là gì?

An Open Graph Preview is a tool that shows how a URL will appear when shared on social platforms. It reads the page's Open Graph and Twitter Card meta tags and renders simulated share cards for networks such as Facebook, Twitter, LinkedIn, and Slack, letting the user verify titles, descriptions, and images before posting. It runs in the browser without an account.
