Claude Code FAQ

Is Claude Code free?: Claude Code itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.

Does Claude Code work on a phone?: No. It needs a computer.
Can I use Claude Code commercially?: We could not confirm this. The page shows 独自(商用), but we have not verified whether what you make with it may be used commercially. Ask the publisher before relying on it.
