Your laptop sleeps. Your agent works through the night
Keep the laptop for the work you watch. Hand the long runs to Claude Code, Codex or OpenCode on a cloud Compute that stays on, keeps its sessions when Wi-Fi drops and opens on your phone. From $39 a month.

When it is the better pick
Keep the laptop for short sessions you sit and watch, offline work, and anything that needs your local files or hardware. Everything longer than a coffee break goes to your Compute.
Questions about this
What about caffeinate or keeping the lid open?
They keep the laptop awake at home. They fail on the train, in a backpack and when the battery runs out. Your Compute stays on without any of that.
Do I lose my local setup?
No. Clone each repo into a project and its CLAUDE.md, AGENTS.md and hooks come with it. Each project gets a home folder of its own, where you sign in and set up your dotfiles once. Ubuntu 26.04 with Docker, Node, Python and the agent CLIs is already installed.
Can I still run the agent locally sometimes?
Yes. Sign in to your CLI on the laptop as usual and keep your Compute for the long runs. Sign in on each side separately; copying auth files between them is what breaks sessions.
