CoSpace JingxuanKang

CoSpace is a macOS daemon and a single-file guest CLI that turn your Mac's compute and AI subscriptions into shared Linux dev spaces. It is for developers and coding agents that need to work in one place — same files, same Claude Code sessions, same memory — and for hosts who hand people they trust a ready-to-run agent environment with no signup, no API keys, and no cloud bill. Each space is a Linux VM (Apple container) on the host's Mac. Guests join over plain ssh; claude, codex, and grok inside are already signed in through a credential gateway on the Mac. Real tokens never enter a space — each space holds only a revocable fake token.
