Preview how your URL looks when shared on social media
OG Debugger fetches any public URL and shows you exactly how it will appear when shared on platforms like Facebook, LinkedIn, X (Twitter), Slack, and WhatsApp. It parses the page's Open Graph (og:title, og:description, og:image, og:url, og:type) and Twitter Card (twitter:card, twitter:title, twitter:image) meta tags and renders a live card preview from them.
It's built for developers, marketers, and content teams who want to confirm their share cards look right before a link goes live. Instead of publishing a post and discovering a missing image or a truncated headline, you paste the URL here and see the parsed tags plus a visual preview instantly.
When you share a link, the receiving platform sends its own crawler to fetch your page and reads meta tags inside the HTML <head>. The Open Graph protocol (created by Facebook) uses tags such as <meta property="og:title" content="...">, og:description, og:image, og:url, and og:type. Twitter/X reads twitter:card (summary or summary_large_image), twitter:title, and twitter:image, and falls back to Open Graph tags when its own are absent.
The og:image is the most common source of problems. Platforms generally want an absolute URL (not a relative path), a reasonably large image (1200x630 pixels is the widely used ratio for large cards), and a publicly reachable file with no login wall. This tool surfaces the raw values it found so you can spot a relative path, an empty content attribute, or a broken image link before the card ever reaches a real feed.
Note that platforms cache what they scrape. Even after you fix a tag, a network may keep serving its old preview for a while. Facebook's Sharing Debugger and LinkedIn's Post Inspector let you force a re-scrape; this tool shows you the current live state of your tags so you know what those crawlers will pick up.
The most common causes are a relative image path instead of an absolute URL, an image behind a login or blocked by robots rules, or a file that is too small. Make sure og:image points to a full https:// URL to a publicly accessible file, ideally around 1200x630 pixels.
Open Graph (og:*) tags are the general standard used by Facebook, LinkedIn, Slack, WhatsApp, and most platforms. Twitter Card (twitter:*) tags are X/Twitter-specific. X reads its own tags first and falls back to Open Graph when they are missing, so many sites only need og: tags plus twitter:card.
Platforms cache scraped previews. This tool shows your current live tags, but a social network may keep serving its cached version until it re-scrapes. Use Facebook's Sharing Debugger or LinkedIn's Post Inspector to force a refresh.
Not necessarily. If twitter:title is absent, X falls back to og:title. Setting og:title, og:description, and og:image usually covers most platforms, and adding twitter:card lets you control whether X shows a small or large image card.
No. The debugger fetches the page the same way a public crawler does, so pages behind authentication, private staging environments, or IP restrictions will not return their meta tags. Test a publicly reachable URL instead.
Yes, it is free to use. It only fetches the public URL you enter to read its meta tags; the URL is not stored or shared, and no account is required.
The page may not include any Open Graph or Twitter Card tags, or the tags may be injected by client-side JavaScript that crawlers do not execute. For reliable previews, render the meta tags server-side in the HTML head.
