Tool insights
Codex with ChatGPT lets you use the ChatGPT web app as a planner and reviewer while Codex does the coding on your machine. The reviewer can read your git diff and test records on its own, so its feedback does not rely only on what the coding agent reports.
Coding agents often judge their own work, and a second opinion usually means pasting diffs and logs into a chat by hand. This project gives ChatGPT direct, read-only access to the session so planning and review happen without copy and paste.
Developers who already run Codex and pay for ChatGPT on the web, and who want an independent reviewer. It is probably not for people without a ChatGPT web subscription, or for anyone who needs an officially supported OpenAI product.
What it does
Codex with ChatGPT is a community-built bridge between the ChatGPT web app and Codex. ChatGPT acts as the planning and review side. Codex does the hands-on coding in your local workspace. The link between them is a read-only MCP server that ChatGPT reaches as a connector.
The project is made by XiaoDuoYa and released as open source under the MIT license. It is unofficial and not affiliated with OpenAI. The version described is V1.
Key features
- ChatGPT as planner and reviewer. The web app takes the thinking role while Codex writes code.
- Read-only MCP server with 10 tools. ChatGPT can inspect the session but the facts do not describe any write access.
- Independent review. ChatGPT can look at the git diff and test records directly.
- OAuth 2.1 with a one-time pairing code. This controls who can connect to your server.
- Workspace containment. Paths are bound to the workspace, and sensitive files are denied.
- Media import. Generated images and videos can be brought in through the c2c asset import.
- Optional stable hostname. You can use a Cloudflare Named Tunnel instead of the default temporary address.
Pricing
The project is free and open source under the MIT license, as of November 2026. No paid plans are listed. A separate ChatGPT Plus or Pro web subscription is required, according to the project description. A pricing page is not stated on the maker's site.
