CRX Blueprint is a developer transparency and security tool. By using this extension,
you acknowledge its primary purpose is the educational and security-focused analysis of browser
extension source code.
1. Privacy & Data Handling
Your privacy is absolute. CRX Blueprint operates under a Zero-Server Architecture:
Local Execution: All extraction, decompression (unzipping), and code formatting happen
100% inside your browser's local sandbox.
No Tracking: We do not track the extensions you view, your browsing history, or your
identity.
No External API Calls: Code is pulled directly from official Chrome/Edge Webstore
servers to your machine. No intermediary servers ever touch the source code.
2. Use Case & Intent
This tool is intended for:
Security Auditing: Verifying if an extension contains malicious code or hidden
trackers.
Learning: Understanding modern extension development patterns.
Debugging: Resolving conflicts between extensions.
3. Intellectual Property
Viewing source code does not grant ownership. You must respect the licenses of the extensions you analyze:
Most extension code is proprietary or under specific open-source licenses (MIT, GPL, etc.).
CRX Blueprint does not facilitate the bypassing of paid licensing or illegal
redistribution of others' work.
Always check the extracted LICENSE file within an extension before reusing any logic.
4. Disclaimer of Liability
CRX Blueprint is provided "as is" without warranty of any kind. We are not responsible for how you use the
information obtained through this tool. Use of extracted source code must comply with your local laws and
the Terms of Service of the respective browser webstores.
5. Open Source Credits
This tool stands on the shoulders of giants. We utilize local versions of JSZip,
Prism.js, and JS-Beautify to handle complex byte-parsing and formatting. All
credits remain with their respective authors.
6. Permission Transparency
To function correctly, the extension requires the following permissions:
downloads: Used solely to save the extracted ZIP or CRX file to your local computer.
contextMenus: Allows you to right-click on web store links to initiate an extraction shortcut.
activeTab: Used to identify the URL of the extension page you are currently viewing so it can be analyzed.
host_permissions (<all_urls>): Required to fetch the extension package directly from official browser web store servers (e.g., Google or Microsoft) to your browser for local extraction.
No data accessed via these permissions is ever sent to any third party or stored outside of your local browser environment.
