Claude CLI stores config in a single ~/.claude/ directory, locking you to one account. Switching means logging out, logging in, reconfiguring.

multi-claude creates isolated profiles with shared settings:

- Isolated config directories per account - Shared MCP servers, env vars, plugins, CLAUDE md — deep-merged on launch - Profiles registered on PATH (claude-work, claude-personal as direct commands) - Cloud backup/restore — sync profiles across machines with a single code - Export/import via base64 tokens - Works on Linux, macOS, Windows, Termux

No daemon, no background process. Pure bash + PowerShell scripts.

npm i -g `@ghackk/multi-claude`

Also available via pip, Homebrew, Scoop, AUR, or curl one-liner.
