How do I update claude-multi and Claude Code?

Two separate things need updating: the claude-multi tool itself, and the Claude Code binary it wraps.

Updating Claude Code

Check what you’re running vs. what’s latest:

claude-multi version

This shows your installed version, the latest published version, and whether an update is available. To upgrade:

claude-multi update

This updates the @anthropic-ai/claude-code package that all your instances share.

Updating claude-multi

Use the same package manager you installed with:

# bun
bun update -g claude-multi

# npm
npm update -g claude-multi

# pnpm
pnpm update -g claude-multi

# Deno
deno install -g npm:claude-multi

What happens to instances during updates

Nothing. Updating Claude Code doesn’t touch your instance directories, they keep their settings, plugins, and conversation history. Since instances are just config directories + wrapper scripts, updates to either tool are non-destructive.
