Open Graph Checker ავტორი Jon Henshaw

See exactly how any web page will look when shared on social media — and catch missing Open Graph tags before you publish.

Open Graph Checker reads the Open Graph metadata of the page you're viewing and shows a live preview of the image, title, and description, just as it will appear when the link is shared. It also gives you a checklist of the key tags and flags anything missing or worth improving — a recommended 1200×630 image, og:url, og:type, and og:site_name.

Works where other tools don't. Because it reads the live, rendered page in your browser — not a re-fetch of the URL — it works on:

• localhost and custom ports
• staging sites behind a login
• pages whose tags are added by JavaScript (Next.js, single-page apps, and other client-rendered sites)

For marketers and developers. Preview how a post, article, or product page will appear before you share it — edit, reload, and preview instantly. No server round-trip.

Privacy by design. It reads the page only when you click the toolbar icon, requests no broad permissions, and sends nothing anywhere — all checking happens locally in your browser.
Free and open source.
