Under the hood it spins up a GitHub Codespace, installs Claude Code, and connects the iOS client to it securely. You can use a full terminal when needed, or a lightweight native UI for monitoring and interaction.

I built this because Claude Code is most useful when it has access to a persistent environment with plugins, tools, and real repos — and I wanted that flexibility away from my laptop.

GitHub gives personal users 120 free Codespaces hours/month, and Catnip automatically shuts down inactive instances.
