Does Conductor replace Codex?

No. Conductor runs Codex as an agent harness. It adds workspace isolation, local setup, review, GitHub workflow, and cross-harness coordination around Codex sessions.

When should I use Conductor with Codex?

Use Conductor when Codex work needs separate branches, copied config, setup and run scripts, review state, checks, PRs, and a path to merge or archive.

Can Conductor run Claude Code next to Codex?

Yes. Conductor can run Claude Code and Codex in the same repository. Use separate workspaces for separate branches, or separate tabs in one workspace when the agents need shared state.

How is Conductor different from Codex cloud environments?

Codex documents cloud environments as a native Codex surface. Conductor focuses on the workspace and review workflow around Codex and Claude Code, with local Mac workspaces and cloud workspace support where available.

Compare

Conductor vs Codex

Codex is OpenAI's coding agent. Conductor runs Codex in workspaces that keep branches, setup, review, and handoff consistent with Claude Code work.

Direct answer

Conductor vs Codex compares OpenAI's coding agent surfaces with Conductor's workspace system. Codex runs through the app, CLI, editor integrations, and cloud environments. Conductor runs Codex inside a project workflow with local setup, repo scripts, review state, PR flow, and Claude Code handoff.

Use Codex directly when you want OpenAI's native app, CLI, editor, or cloud workflow. Use Conductor when Codex work should follow the same branches, setup scripts, checks, and review process as the rest of your agent work.

Where Codex fits

Codex gives developers native OpenAI surfaces for agent work. Teams may still want one project workflow for local config, run commands, diffs, checks, and the branch they decide to merge.

Where Conductor fits

Conductor treats Codex as one agent harness inside a workspace. The workspace provides the branch, working tree, setup, run scripts, review state, and PR path.

1
Start from a task, issue, branch, or pull request.
2
Create a workspace with its own branch and working tree.
3
Copy local config, run setup, and start the project with workspace scripts.
4
Run Claude Code or Codex, or open the workspace in your editor when editing there is the right surface.
5
Review the diff, comments, checks, todos, and pull request before merge.
6
Merge the branch and archive the workspace when the work is finished.

How Conductor implements the workflow

Conductor keeps Codex work tied to the same workspace model it uses for Claude Code, so teams can switch or hand off without changing the surrounding workflow.

Workspace isolation

Create a separate branch, working tree, run environment, and .context folder for each task.

Runnable workspaces

Copy env files, run setup scripts, start dev servers, reserve ports, and share defaults with conductor.json.

Review to merge

Review diffs, send comments back to agents, watch checks, create PRs, merge, and archive finished work.

Multiple harnesses

Run Claude Code and Codex in the same workspace when they need shared state, or in separate workspaces when they do not.

Test a worktree in main

Use Spotlight to run one workspace from the repo root when the project depends on a fixed port, local database, or expensive build cache.

Cloud support

Use local workspaces on your Mac, or run agents in cloud workspaces when local resources are the bottleneck.
