The short answer

Pick Claude Code on the web if you run Claude Code. Pick Codex cloud if you run Codex. Both are included in the plan you already pay for.

Read this first

The useful distinction

Claude Code on the web: the same Claude Code harness, hosted on Anthropic VMs. Connect GitHub, submit a task, review the PR. Status: research preview.

Codex cloud: OpenAI's coding agent, running background tasks in isolated ChatGPT cloud environments. Included with ChatGPT plans. Not the 2021 Codex model.

Decision

When each side wins

Claude Code on the web wins when

  • You only run Claude Code and want no fee beyond your Claude plan.
  • You want claude --teleport to pull a cloud session back into your terminal.
  • Slack @Claude and claude.ai connectors come with the plan.

Codex cloud wins when

  • You already pay for ChatGPT, and cloud tasks come with the plan.
  • You want the agent offline during its work phase, with secrets removed first.
  • You want @codex on GitHub issues and pull requests, and GitLab in beta.

Rush

Where Rush sits

Rush runs both, plus OpenCode, in one Project, and starts them from an API with an API key.

Honest limits

Skip Rush if

  • Rush runs three agents: Claude Code, Codex and OpenCode. It does not host an agent you wrote yourself.
  • Repositories come through the Rush GitHub App. A GitLab or Bitbucket repository cannot be a run's repository yet.
  • There is no self-hosted or customer-VPC deployment, and we do not publish a compliance report today.
  • Compute is metered. Free includes 5 agent-hours a month and Pro 40, each with a weekly ceiling.
  • You review the pull request. Rush does not merge for you.
