Open Graph checker & preview

Only for Mac

Mac

See how your links look when shared on every major platform — then fix the meta tags holding them back, all in one fast, native macOS app. Web Metatag Viewer fetches any web page and shows you exactly how it will look the moment it's shared — across every platform that matters. See live, accurate previews of: • Open Graph (Facebook and generic) cards • Twitter / X Cards • The native macOS link preview • Slack, Discord, LinkedIn and WhatsApp cards • A Google search-result preview But it doesn't just show your tags — it optimizes them. A built-in rule engine checks for missing, duplicate, or oversized meta tags (Open Graph, Twitter Card, canonical, viewport, image URLs) and gives you ranked, actionable fixes so your links look their best everywhere. EXPORT, YOUR WAY • Copy any tag's value or its full HTML • Copy the complete "meta" block • Copy a full optimization report • Copy a ready-to-paste prompt that tells your code editor exactly how to fix the tags EVERYTHING IN ONE NATIVE WINDOW • Live share-card previews across major platforms • Meta-tag validator with clear, prioritized suggestions • Google search-result preview • Recent-URL history, one click away • One-click copy and export • Native, sandboxed, and private — it reads pages to inspect their tags and never writes your files or tracks you Whether you're shipping a landing page, a blog post, or a product launch, Web Metatag Viewer helps you ship links that look sharp and read well — before anyone clicks.
