What is it?

Codex with ChatGPT moves the planning and review work of a coding session to the ChatGPT web app you already subscribe to, while Codex keeps ownership of editing, running shell commands and tests. It targets the case where API or Codex quota is scarce but web ChatGPT quota goes unused. No API key is required and no reverse proxy is used; the project relies on the official web UI plus a local bridge.

The local C2C bridge runs on loopback and exposes ten read-only MCP tools, such as read_file, search_workspace, git_diff and test_status. ChatGPT pulls only the lines it needs, so the repository is not uploaded. Codex and ChatGPT exchange small structured state messages through the INIT, PLAN, EXECUTED, REVIEW and DONE sequence. The connection uses OAuth 2.1 with PKCE and a one-time pairing code, and sensitive files such as .env and keys are denied by default.

Setup is handled by a Codex Skill that installs the bridge, configures a Cloudflare tunnel and pairs the ChatGPT connector. A stable hostname requires a Cloudflare account with a domain. The project is V1 and is not affiliated with OpenAI.

Key features

  • 01Lets ChatGPT web review and plan while Codex executes edits and tests.
  • 02Exposes ten read-only MCP tools for reading files, searching, and inspecting git diffs and test status.
  • 03Uses OAuth 2.1 with PKCE and a one-time pairing code for the connection.
  • 04Denies sensitive files such as .env and keys by default and supports a .c2cignore file.
  • 05Exposes the bridge through a Cloudflare tunnel, with an optional stable hostname.

Use cases

  • Offloading planning and code review from a scarce Codex or API quota to a ChatGPT web subscription.
  • Having ChatGPT independently check Codex's git diff and test results after an execution step.
  • Working on a local repository without uploading it to a third-party service.
