OGP Dev Tool

A developer tool to simulate OGP drawing results. Localhost results can also be easily previewed.

OGP Dev Tool gives web developers an instant preview of how a page's Open Graph Protocol (OGP) metadata will appear on social networks and popular UI component libraries — all without leaving Chrome. Open the DevTools panel (F12 → OGP tab), navigate to any page, and see a full breakdown of every OGP tag alongside live-rendered previews. ────────────────────────── 🔍 What you can inspect ────────────────────────── OGP Dev Tool reads and displays all major OGP-related meta tags including: • og:title, og:description, og:image, og:url, og:type, og:locale • og:image:width / og:image:height / og:image:type • og:site_name, og:video, og:audio • twitter:card, twitter:title, twitter:description, twitter:image, twitter:creator • fb:app_id, article:author, article:published_time, and more ────────────────────────── 📱 Live social & UI previews ────────────────────────── See exactly how your metadata renders in five preview styles: • X (Twitter) — card preview with image, title, and description • Facebook — link preview card • shadcn/ui — clean card component • Ant Design — card component • Material UI — card component ────────────────────────── ⭐ Key benefits ────────────────────────── ✅ Works on localhost — test OGP before deploying; no tunnels or staging servers required ✅ No page reload needed — hit the Reload button in the panel to re-read metadata instantly ✅ Copy any value to clipboard with one click ✅ Dark mode support — follows your DevTools preference ✅ Three UI languages — English, 日本語, 中文 ✅ Completely local — no data is ever sent to external servers; all inspection happens in your browser ────────────────────────── 👨‍💻 Who is this for? ────────────────────────── Front-end developers, SEO engineers, and content teams who need a fast feedback loop when writing or debugging OGP tags. Instead of sharing a URL with a social debugger tool and waiting for a re-scrape, you get instant visual feedback right inside DevTools on any page — including localhost. ────────────────────────── 🔒 Permissions ────────────────────────── • storage — saves your language and theme preferences locally • Access to all URLs — required to inspect OGP metadata on any page you visit Source code: https://github.com/Uno-Takashi/OGP-Dev-Tool
