Overview

A Security-First, Open-Source Userscript Manager.

Shieldmonkey is an open-source userscript manager designed with security and transparency as top priorities. Built on the concept of "Safety over Convenience," it protects your browser environment from unintended network communications and malicious scripts. 【Key Features】 🛡️ Fundamentally Incapable of External Communication Shieldmonkey is designed with a Strict Content Security Policy (CSP) that makes it **fundamentally impossible** for the extension itself to communicate with external servers. Your data is never sent out without your knowledge, and no external scripts are ever loaded behind your back. 🚫 You Are in Complete Control There are no automatic updates or cloud backups. All script updates and changes are performed solely under your supervision, preventing unexpected changes or the silent injection of malicious code. 🔍 Transparency You Can Trust The code running inside is provided in a readable, un-minified format. Security-conscious users can verify the safety of the extension at any time. 📦 Secure Supply Chain We implement strict security measures throughout our development process to proactively eliminate risks from third-party dependencies. 【Features】 - Script management (Install, Edit, Delete, Disable) - Advanced script editor (Powered by CodeMirror 6) - Support for `.user.js` format - Import/Export to local files Ideal for users who value privacy above all else and for engineers who demand complete control over their browser's behavior.
