Claude Cage

Claude Cage is a lightweight Linux virtual machine desktop application combining a terminal, browser, and file editor.

Claude Cage is a desktop application designed to run a lightweight Linux virtual machine that integrates a Linux terminal, browser, and file editor into a single window. It isolates network traffic and device fingerprints, including timezones and languages, to protect user accounts during interactions with Claude and Claude Code. The application includes built-in proxy management supporting subscription imports and node selection, maintaining offline status when checks fail. Tools, files, and login states persist in a virtual disk across sessions. It runs on macOS, Windows, and Linux, requiring users to provide their own proxy and Claude accounts.
