Og Link Preview

OG Link Preview lets developers and content creators instantly inspect Open Graph and Twitter Card meta tags on any webpage — and see exactly how links will look when shared on social media.

Works on localhost, staging, and production sites. No page source digging needed.

KEY FEATURES

🔍 Meta Tag Inspector
• View all og: and twitter: tags in one place
• Organized in tabs for quick browsing
• Fallback detection from standard <title> and <meta name="description"> tags

Realistic Social Previews
See how your link will render on:
• Facebook — title, description, image card
• Twitter/X — summary and summary_large_image card layouts
• LinkedIn — title, site name, and image
• Slack — unfurl preview format
• WhatsApp preview — See exactly how your link appears in WhatsApp chats, with the green bubble, image, title, description, and domain

Validation & Scoring
• Errors for missing og:title, og:description, og:image
• Warnings for og:url, og:type, twitter:card, and character limits
• Pass/fail score badge at a glance
• Client-side rendering detection — Detects when OG tags are injected by JavaScript only and warns that social media crawlers won't see them
• Crawler-accurate previews — When CSR-only tags are detected, all previews, validation, and tag lists show what crawlers actually see (raw server HTML) instead of the misleading JS-rendered DOM
• Favicon & title fallbacks — Mimics real crawler behavior by falling back to <title> and favicon when OG tags are missing from server HTML

PERFECT FOR
• Developers testing metadata before launch
• SEO and marketing teams auditing pages
• Content creators checking how posts will preview
• QA teams verifying staging vs. production
