Open Graph Preview
We load the page HTML (read-only) and read <meta property="og:*"> and <meta name="twitter:*"> tags, then show simulated link previews. Private networks and blocked hosts aren’t fetched. Enter a domain (we add https:// when needed) or a full URL. After a successful fetch, use Copy link to share a URL that opens this same preview for colleagues or clients.

Add tags in your HTML <head>, for example:
<meta property="og:title" content="Your title">
<meta property="og:description" content="Short summary for shares.">
<meta property="og:image" content="https://perimeter-check.com/og.jpg">
<meta property="og:url" content="https://perimeter-check.com/this-page">
<meta name="twitter:card" content="summary_large_image">
Use absolute https image URLs (ideally around 1200×630). Most CMS tools and CDNs can generate these for you.
