+ strengths

  • Official apps for macOS, Windows and (preview) Linux, plus phone control of a connected computer from ChatGPT on iOS/Android
  • Git worktrees for parallel chats with Local/Worktree handoff; scheduled tasks can run on background worktrees
  • Can connect to projects on an SSH host; MCP, skills, plugins and subagents are documented
  • Included in every ChatGPT plan including Free, with App Server and Codex SDK for programmatic control

! weak points

  • Closed-source app; runs OpenAI's Codex agent, not arbitrary third-party agents (not verified that other agents can be hosted)
  • Requires a ChatGPT account; usage limits depend on plan, and Free/Go model access is described as subject to rollout
  • Linux build is still a preview; remote host control supports only Mac and Windows hosts
  • Product is being merged into the broader ChatGPT desktop app, so naming and docs locations have shifted

~/who it is for

best for
Developers with a ChatGPT subscription who want a first-party GUI for parallel Codex tasks with worktrees and phone follow-up.
look elsewhere if
Teams wanting an open-source workspace or one that drives Claude Code and other vendors' agents.
