Claude-Cage: Fully Isolated Virtual Environment for Claude Account Protection

A desktop application that alleviates the burden of VPS and browser environment configuration when using Claude. It runs native virtual machines on macOS, Windows, and Linux hosts, integrating Claude Code, the browser, and the terminal into a single workbench. Unlike conventional methods, it completely separates network traffic and browser fingerprints (such as clock and language) from the host to reduce account security risks.

Users can directly import and apply proxy settings based on Clash or Mihomo. Built-in network and isolation inspection tools verify that the environment is functioning correctly and automatically block external communication if an inspection fails. It also supports managing multiple Claude Code subscription accounts within a single environment and switching sessions on a per-account basis as needed.

It supports integration with mobile devices for remote work continuation and allows deploying the environment to your own VPS server via SSH. It can securely connect to other devices within a private network using Tailscale. This project is released under the MIT license, is developed based on agent-vm, and is an independent community project unrelated to Anthropic.

It is suitable for developers who want to use Claude stably while minimizing the complexity of environment setup and the risk of account suspension. It runs on Apple Silicon with macOS 14 or later, Windows 10/11, and major Linux distributions, and can be used immediately with just the installer file, without requiring separate installation of Docker or Go.
