Everything you need to debug metadata

Nine features packed into a lightweight Chrome side panel.

Auto-detects Active Tab

No copy-pasting needed. The extension automatically picks up the active tab's URL and fetches its metadata instantly.

Open Graph Tags

Inspect og:title, og:description, og:image, og:url, and every other OG property in one clean view.

Twitter Card Tags

See twitter:card, twitter:title, twitter:image, and all Twitter Card meta tags at a glance.

SEO Meta Tags

Displays the page title, meta description, canonical URL, and robots directives—everything that matters for search.

Auto-refresh on Navigation

Switch tabs or navigate to a new page and the panel updates automatically—no manual refresh needed.

Manual URL Input

Analyse any URL without navigating to it. Type or paste a URL directly into the panel for instant inspection.

5-Minute Smart Cache

Results are cached locally for 5 minutes so re-opening the panel is instant without redundant API calls.

Server-Side Fetching

Metadata is fetched via a Cloudflare Worker, so you see the real server-rendered tags—not client-patched ones.

Dark & Light Mode

Theme preference is persisted locally so the panel always matches your workflow.

How it works

  1. 1

    Click the toolbar icon

    Open the Metatag Debugger from the Chrome toolbar to launch the side panel.

  2. 2

    Navigate to any page

    Your metadata is fetched and displayed immediately, organised by category—no interaction required.

  3. 3

    Switch tabs freely

    The panel updates automatically whenever you navigate to a new page or switch tabs.

  4. 4

    Or enter any URL manually

    Use the manual input field to inspect any URL without navigating to it.

Your privacy is not an afterthought

No analytics. No tracking. No account. The extension only ever sees the URL of the tab you're actively viewing—nothing else. Results are cached locally in your browser and never leave your device.
