Cube Computer

Cube provides an always-on cloud computer for agents, eliminating the need for server maintenance, SSH setup, or manual restarts.

The company allows users to assign Claude Code to a dedicated always-on Linux cloud computer, enabling session persistence even after closing a laptop.

The page describes how to run OpenAI Codex on a cloud-based Linux machine, requiring only a GitHub sign-in and installation to maintain sessions after closing.

The company enables users to run multiple Claude Code or Codex agents simultaneously on a persistent Linux cloud machine instead of a laptop.

The company offers cloud-based always-on computing for coding agents, allowing users to access work remotely without keeping a laptop powered.

The page explains how to maintain Claude Code and Codex sessions after closing a laptop, run agents in parallel, and troubleshoot overnight disconnections.

The page lists four methods to keep Claude Code running after a laptop closes, including keeping the Mac awake, using tmux on a server, cloud sessions, or an always-on computer.

The page provides instructions for running the Codex CLI on a remote Linux server or VPS with tmux to maintain sessions after disconnection, including a managed alternative.
