codex-with-chatgpt
Bridges paid ChatGPT web quota into Codex CLI as a read-only planning brain.
This open-source tool lets Codex CLI hand planning and review to the ChatGPT web app you already pay for, instead of burning API tokens on that work — Codex still does all the actual execution. The connection is a read-only, OAuth-protected MCP bridge to your current workspace: ChatGPT reads only the lines it needs and your repository is never uploaded. Setup needs Git, Node.js 20+, and cloudflared for the tunnel; it's a GitHub project with 3.8k stars, no company or pricing behind it.

What holds up
- +Uses ChatGPT Plus/Pro web quota you already pay for instead of burning Codex API tokens
- +Read-only, OAuth-protected MCP bridge — your repo is never uploaded, only specific lines are read
- +Free and open source, 3.8k GitHub stars, no API keys or reverse proxy required
Mind the limits
- −Needs Git, Node.js 20+ and a cloudflared tunnel installed — not a one-click app
- −Depends on ChatGPT's web session staying logged in — logins, CAPTCHAs or 2FA interrupt it
