Frequently Asked Questions

Find Quick Answers

What file formats are supported for upload?

You can upload .crx files (Chrome extension packages) or .zip files containing extracted extension files. The tool will automatically detect and parse the manifest.json.

Can I analyze extensions directly from the Chrome Web Store?

Yes, you can enter the extension's URL from the Chrome Web Store (e.g., https://chrome.google.com/webstore/detail/...). The tool will fetch and analyze the extension's public data, including permissions and metadata.

What does the security score mean?

The security score (0-100) is calculated based on the permissions requested by the extension, with higher-risk permissions (e.g., 'tabs', 'debugger', 'nativeMessaging') reducing the score. A score above 70 is generally safe, while below 50 indicates potential risks.

Is my uploaded data stored or shared?

No, all analysis is performed locally in your browser or on our secure servers temporarily. Uploaded files and URLs are not stored permanently or shared with third parties.
