Cube Computer
A cloud computer for running coding agents.
As agents run longer on bigger tasks, running them locally means keeping your laptop open and on wifi. Cube gives you a full Linux computer in the cloud with one-click setup, and a desktop app built for working with the agents on it.
One sidebar shows every machine: your cloud computer and your local Mac side by side, with every repo, worktree, and session on each. Each agent session gets its own isolated worktree, so agents never queue for a working directory and nothing lands on your branch by accident. Terminals are owned by a background daemon rather than the window, so agents keep running when the app closes and reattach when it comes back, from any client.
Cube grew out of Collaborator. It’s an Electron app, with the same interface running unmodified in the browser against a cloud machine. Built with React, Tailwind, and xterm.js.
