Octopus brings Codex to iPhone and iPad. Connect to your Mac, development server, or remote workspace and keep real coding threads moving from anywhere. It is not another closed cloud IDE. Octopus is a mobile control surface for the environment you already use: connect through Codex app-server or SSH, browse workspaces, projects, and recent sessions, return to active threads, and follow Thinking, Waiting, and Ready states in real time. When an agent needs a decision, resolve approvals with Allow, Allow for Session, or Deny. Use text, voice, images, and files to add context without returning to your desk. Review automation runs, start a task again, inspect history, and jump back from notifications or Live Activities when work changes state. Built for developers who want to: • Monitor AI coding agents from iPhone • Resume Codex threads away from the desk • Approve commands, permissions, and structured questions remotely • Keep Mac, server, workspace, and thread context organized • Dictate quick prompts, bug notes, and test results by voice Key features: • Codex app-server and SSH connections • Server, project, thread, and recent session management • Runtime status, notifications, and Live Activity deep links • Approval cards for command and permission decisions • Markdown messages, tool results, image input, and file context • Automation list, run-now actions, and run history • SSH host fingerprint confirmation and credentials stored in device Keychain • Octopus turns your phone into a second development screen, so you can stay close to the code even when you step away from the keyboard.
