Social Preview Checker Browser Extension

Open LinkGlimpse from the toolbar and it automatically checks the current page. See social cards, a Google search preview, metadata diagnostics, image checks, redirects, and copy-ready fixes without leaving the extension.

Add to Chrome Add to Firefox

Free to install. No LinkGlimpse account required.

Automatic on open

Click the toolbar icon and the current page is checked immediately—there is no URL form or inspect button.

Minimal permissions

Only the active tab and LinkGlimpse API—no browser history, cookies, credentials, or continuous background access.

Everything in the popup

See the score, platform previews, metadata values, extracted tags, and copy-ready fixes without opening another page.

Open source and inspectable

The extension source is public. Review its permissions, inspect the implementation, or build both browser versions locally.
