CRXCheck — Browser Extension Security

Scan and manage your browser extensions with real-time security analysis powered by CRXCheck.com

Know exactly what every extension in your browser does with your data. CRXCheck scans all of your installed Chrome extensions and gives each one a real-time security score from 0-100, so you can spot risky extensions before they cause harm. HOW IT WORKS • After install, CRXCheck automatically scans every extension you already have • New extensions are scanned the moment you add them • Each extension gets a security score, a risk level (Low / Medium / High / Critical), and a clear recommendation: use it or uninstall it • Open the full report for any extension, including its permission list, content scripts, and category scores • One click to open the extension's page on CRXCheck.com for the detailed public report AT A GLANCE • Badge on the toolbar shows how many high-risk or unscanned extensions are active • Click the icon for an instant risk summary • Right-click any Chrome Web Store page to scan that extension in one click • Open the full dashboard to see all installed extensions, sorted by risk • Auto-scan every new extension you install FULL CONTROL FROM ONE DASHBOARD • Enable or disable any extension • Uninstall risky extensions directly • Filter by risk level or enabled state • Rescan everything with one click WHY CRXCheck Every extension you install gets access to some part of your browser. Many ask for far more permission than they need. CRXCheck makes those requests visible and gives you a simple score to decide what to keep. WHAT WE COLLECT CRXCheck only sends the extension IDs of your installed extensions to crxcheck.com to look up security data. We never read your browsing history, passwords, or personal data.
