ccslot

ccslot is a developer tool that lets you run multiple Claude Code accounts on one machine while sharing your projects, skills, plans, and settings between them, separate logins, shared brain. Claude Code normally stores everything in a single ~/.claude directory, which forces you to log out and back in to switch accounts. ccslot creates a separate config directory for each account (a slot) and symlinks the parts worth sharing, projects, skills, plans, and settings, back to the original, so each account keeps its own authentication while reusing the same working context. It supports cross-account /resume to continue conversations, shell aliases for quick switching, and separate MCP server credentials per slot. Installation is via npm (for example, npx ccslot add work), and it works on macOS, Linux, and Windows (Node 22+ required). It is free and open source under the MIT license. ccslot is best for developers who legitimately use more than one Claude Code account; note the docs warn against running two accounts in the same repo at once, that Windows without Developer Mode falls back to junctions/hard links, and that .credentials.json is never shared by design.

Best for developers who use more than one Claude Code account and want separate logins but shared projects, skills, and settings.
