Skyflo vs OpenAI Codex

Codex runs in the ChatGPT desktop app, CLI, IDE, GitHub, and Codex Cloud. Skyflo runs Codex next to Claude Code, Cursor Agent, and other agents you already use, on your Mac or in Skyflo Cloud.

Compare the current products across the boundaries that matter when several agents share the work.

At a glance8 dimensions, no winner score

OpenAI CodexDocumented strength

Codex lives in the ChatGPT desktop app alongside the CLI, IDE extension, and Codex Cloud. It documents parallel worktrees, cloud tasks that keep working while your computer sleeps, subagents, GitHub pull-request review, scheduled tasks, a built-in browser, and computer use.

SkyfloWhere it sits

Skyflo runs Codex as one of seven external agents, with your own sign-in on the Mac and on Skyflo's included models in Skyflo Cloud, under one access mode, with an append-only record and source-linked memory for each mission.

The decision.

Use Codex directly, or through Skyflo when a mission needs other agents too?

Codex on its own covers the ChatGPT app, CLI, IDE, GitHub and Codex Cloud, with worktrees, subagents and scheduled tasks. Run it inside Skyflo when the same mission should also use Claude Code, Cursor Agent or Skyflo's own agent, with one access mode, one record and memory on your Mac, or should move to Skyflo Cloud.

Runs inside Skyflo. Skyflo runs Codex inside its missions: on your own Codex sign-in on the Mac, and on Skyflo's included models in Skyflo Cloud.

Choose OpenAI Codex when

  • You want Codex directly in the ChatGPT desktop app, CLI, IDE, GitHub, or Codex Cloud.
  • Several independent tasks should run in parallel worktrees or cloud environments on OpenAI models.
  • Scheduled tasks and pull-request review inside ChatGPT are the main workflow.

Choose Skyflo when

  • Codex and Claude Code, or another agent, should work on the same mission under one access mode.
  • Each mission's events should stay in an append-only record on your Mac.
  • Source-linked memory from finished missions should carry into later missions, and Skills you approve should be removable.

You might use both when

Use Codex directly for focused tasks and Codex Cloud work, and run it inside Skyflo when a mission also needs another agent, one access mode, and a record of what each agent did.

Codex vs Claude Code: which should you use?

Choose by model family, plan, and where you work. Codex runs OpenAI models and lives in the ChatGPT desktop app, the Codex CLI, the IDE extension, and Codex Cloud, where each task gets its own workspace and keeps running while your computer sleeps. Claude Code runs Claude models in the terminal, IDE, desktop app, web, and Slack.

If you already pay for ChatGPT Plus or Pro, Codex is included. Claude Code needs a Claude Pro, Max, Team, or Enterprise plan, or a Claude Console account. Both work on several tasks in parallel, so the deciding factor is usually the models and plan you prefer.

In Skyflo

A Skyflo mission can use both, switching agents between turns under one access mode, with every turn on one record on your Mac.

Codex CLI vs the ChatGPT desktop app: what is the difference?

Codex is available in both. The ChatGPT desktop app, for macOS, Windows, and Linux, keeps projects and chats in one workspace with files, a browser, computer use, and scheduled tasks; you choose Codex in the app and start a new chat. The Codex CLI works in your terminal against a local repository, and codex exec runs it from scripts and CI.

How you sign in decides the features. With a ChatGPT plan, Codex works on the web, in the CLI, the IDE extension, and iOS, with cloud features such as automatic code review. With an API key, Codex works in the CLI, SDK, and IDE extension, billed at API rates, without the cloud features.

How much does Codex cost?

Codex comes with ChatGPT plans. As listed on October 22, 2026, Free and Go ($8 a month) include GPT-6 Luna in the desktop app, subject to rollout. Plus ($20 a month) adds Codex on the web, in the CLI, the IDE extension, and iOS, cloud integrations such as automatic code review, and GPT-6.1 Sol. Pro costs $100, $200, or $500 a month for more usage. Business is $20 per user per month billed annually for two or more users, or $25 billed monthly.

With an API key, Codex usage is billed at API token prices instead, and cloud features such as GitHub code review are not included. OpenAI notes that API token prices are separate from subscription usage, so do not use them to estimate what a plan includes.

In Skyflo

Skyflo Free runs Codex on your own ChatGPT sign-in, with no charge from Skyflo. On paid Skyflo plans, a mission can also run Codex in Skyflo Cloud on Skyflo's included models, with no provider sign-in on that machine.

Skyflo vs OpenAI Codex, dimension by dimension.

The same 8 dimensions run on every engineering comparison, including the ones where OpenAI Codex is stronger. A row reading “not addressed” means the reviewed documentation does not cover it, which is not the same as the product lacking it.

OpenAI Codex and Skyflo across 8 dimensions
DimensionOpenAI CodexSkyflo
Primary unit of workA chat or task that produces a reviewable result.A mission: one goal with its conversation, the agents working on it, their approvals, and its record. It persists across sessions and goes idle rather than closing.
Execution environmentLocally in the ChatGPT desktop app, CLI, or IDE extension under an OS-enforced sandbox, or in Codex Cloud, where each task gets its own isolated workspace and keeps working while your computer is asleep.Agents run on your Mac by default. On a paid plan you can start or move a mission to Skyflo Cloud, a machine Skyflo runs for that mission, which keeps working while your Mac sleeps. Only Codex and Skyflo's own agent run there; Claude Code stays on your Mac. A mission started there from a GitHub repository opens a pull request.
Agent and model choiceOpenAI models such as GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna, with subagents and parallel chats; local clients can also use custom providers. The desktop app imports setup and recent work from Claude Code, Claude Cowork, and Cursor.Skyflo's own agent plus seven external agents: Codex, Claude Code, Cursor Agent, Antigravity, Grok CLI, OpenCode, and Pi, and one custom ACP agent added through a manifest file. External agents use their own sign-in and models; Skyflo's own agent uses included models on paid plans or your Moonshot or Z.ai key. Orchestrate runs several on one mission and can pick the lead.
Cross-repository coordinationA local project can hold several folders, and the desktop app reviews diffs across every repository in it; Codex Cloud environments are set up from GitHub repositories.A workspace is an ordered set of up to eight registered Git checkouts, and one mission can span them. In Skyflo Cloud a mission spans one to five. Each writing specialist works in its own worktree, so edits stay apart while the work runs; integrating them is still a change you review.
Approval and mutation boundariesAn OS-enforced sandbox plus an approval policy, with network access off by default. Permission modes include Ask for approval, Approve for me, where a separate reviewer agent decides eligible requests, and Full access; which modes appear depends on the app version, environment, and organization.One access mode governs every agent on a mission, Skyflo's own and the external ones. Skyflo answers each agent's permission requests by that mode and records the decision. In Full access, the default for a new Auto mission, prompts are off and folder confinement is lifted. Orchestrate starts at Ask for approval, and Plan mode waits for you to approve the plan.
Independent reviewCodex reviews local changes and GitHub pull requests against repository guidance.In Orchestrate missions, Skyflo adds a separate reviewer by strategy and risk, and Skyflo's own agent can start one. The reviewer can read, search, ask, and report, but cannot edit files. Not every mission is reviewed, and a review is a second opinion, not a guarantee.
Browser, terminal, and automation evidenceTerminal workflows, scheduled and event-triggered tasks, a built-in browser in the desktop app, and computer use on macOS and Windows are documented.Code, browser, terminal, and automations share one workspace, where you and Skyflo's own agent work in the same browser and terminal. Each mission keeps an append-only record on your Mac of approvals, Skyflo tool calls, including external agents' calls through Skyflo's tools, and review findings, every event hash-linked to the one before it.
Cross-mission memory, provenance, and user controlOpt-in local memories are generated from eligible prior chats, stored under the Codex home directory, and controlled per chat and globally. They are off by default.Personal memory stored on your Mac, learned from finished missions with a link to its source. Skyflo keeps a memory when the evidence supports it; otherwise it waits for you to keep, correct, or dismiss it, and you can remove any memory later. A workflow verified in two repositories can become a Skill once you or an independent agent approves it. Reverting a Skill or a routing change alters what Skyflo does next, not past work.
