ccss - Claude Code Session Switcher

Switch Claude Code login sessions while sharing settings and history across them.

Each named session is a symlink to ~/.claude, so settings and conversation history stay shared with your default profile — only the login session is separated. Sign in once per session and switch between accounts without losing your customizations.

Install

bun install -g him0/claude-code-session-switcher

or

npm install -g him0/claude-code-session-switcher

Run without installing

bunx him0/claude-code-session-switcher

or

npx him0/claude-code-session-switcher

Usage

ccss                                  Show help
ccss create <name>                    Create a new session
ccss list                             List all sessions
ccss delete <name>                    Delete a session (--force to skip prompt)
ccss [-s <name>] exec <cmd> [args...] Run <cmd>; -s sets CLAUDE_CONFIG_DIR, omit for default

Examples

# Create a session
ccss create work

# Launch Claude Code with that session
ccss -s work exec claude

# Pass additional arguments through to claude
ccss -s work exec claude --resume

# Run any command with the session's env (useful for debugging)
ccss -s work exec bash
ccss -s work exec env | grep CLAUDE

# List sessions
ccss list

# Delete a session
ccss delete work

Frequent users can alias their main flow:

alias cc-work='ccss -s work exec claude'

How it works

Sessions are stored under ~/.config/ccsession/sessions/. Each session is a symlink to ~/.claude at creation time, so settings and conversation history are shared across all sessions. When running ccss -s <name> exec <cmd>, ccss sets CLAUDE_CONFIG_DIR to the session directory and spawns <cmd> — only the login session is separated.

Environment variables

When ccss exec launches a command, these variables are set in the child process:

• CCSS — always 1, a marker that the command is running under ccss
• CLAUDE_CONFIG_DIR — path to the session directory (only set when -s <name> is given)
• CCSS_SESSION_NAME — the session name (default when -s is omitted)

CCSS and CCSS_SESSION_NAME are handy for showing the current session in your shell prompt or status line.
