Cube

Cube is a personal cloud computer for running AI coding agents such as Claude Code and Codex. Each Cube is a persistent machine in the cloud, controlled from a Mac app, so agents keep working after the laptop lid closes. Developers sign in with GitHub, open a repository on their Cube and start agents, run commands and check progress from a sidebar that lists repositories, worktrees and running sessions. It is built for developers who run long agent sessions and do not want them tied to a local machine. Cube supports a long list of terminal agents, including Claude Code, Codex CLI, OpenCode, Gemini CLI, Aider, goose, Amp, Cursor CLI, GitHub Copilot CLI, Qwen Code, Kiro CLI and others, installed and run directly on the cloud machine with access to its files and tools. Users can also connect over SSH from editors and terminals such as VS Code, Cursor, Zed, Warp, Ghostty, iTerm2 and Termius. Git worktrees keep separate branches apart, sessions can be grouped into screens, and a phone view shows what agents are doing and lets users send follow up instructions. Pricing is based on credit rather than subscription plans. Users add credit and choose the machine's CPU, memory and SSD size, and the app shows the current hourly, daily and monthly rate before a configuration is applied. A running machine uses credit for compute and storage; a paused machine is charged for persistent storage only. Specific rates are shown in the account, not on the public pricing page. Eligible new accounts can claim free credit by saving a payment method, and agent subscriptions and model usage are billed separately by their providers. Closing the app does not pause the machine, so compute charges continue until the user pauses it.
