Check before choosing

It is a Codex-only GUI; the open Codex CLI repository does not make the proprietary desktop interface code-verifiable.

Workflow fit

Existing evidence gates classify four predefined workflows. Bands are non-numeric and do not rank product quality.

  • One agent + review

    Strong fit

    Stay close to one coding session and inspect changes in a dedicated visual surface.

    Current sources document visual review, workspace isolation.
  • Parallel local tasks

    Strong fit

    Run several coding tasks on one machine without their branches or files colliding.

    Current sources document parallel sessions, workspace isolation, visual review.
  • Remote control

    Good fit

    Start or revisit coding work away from the machine where the repository is running.

    Every required mechanism is documented; current sources do not establish the preferred shared team access mechanism.
  • Shared team workspace

    Conditional fit

    Let teammates enter the same live workspace to watch, steer, preview, or review work.

    The product may fit, but current sources do not establish shared team access.

Harness coverage

Codex only. Local desktop use accepts ChatGPT sign-in or an OpenAI API key, with the corresponding plan or API billing.

Workflow mechanisms

Unknown means the current first-party record does not establish the mechanism; it is not converted into evidence of absence.

4 of 5 documented
  • parallel sessions

    Documented

    The desktop Codex experience can run multiple independent chats in one project.

  • workspace isolation

    Documented

    Codex can create a managed Git worktree for each independent desktop chat.

  • visual review

    Documented

    The coding surface includes inline diff editing and pull-request review.

  • remote execution or access

    Documented

    Chat handoff moves a chat and Git state between local and connected remote hosts.

  • shared team access

    Not established

    Current first-party desktop documentation does not establish shared live teammate access to one task.

First-party ChatGPT desktop workflow; Codex is available as a dedicated mode in the same app.

Technical and public context

Implementation inspection and source-native activity provide investigation context. Neither changes workflow fit.

Implementation record

The GUI implementation is proprietary. Current claims rely on first-party product documentation rather than a public-code inspection.

First-party evidence

Sources establish specific current GUI claims; their count does not add fit points.
