WTAgent: Turn ChatGPT Web into a Codex-style Local Coding Agent (Open Source)

A developer released WTAgent, a free, MIT-licensed CLI that turns ChatGPT Web and Claude Web accounts into Codex-style local coding agents. The tool drives a dedicated Chrome profile signed into the user's web AI subscription, requiring no model API key, MCP server, or tunnel, and supports switching between models including Claude, DeepSeek, Gemini, Grok, Kimi, and GLM. It runs on macOS, Linux, and Windows via WSL2 with Node 20.17+ and Chrome/Chromium.

I kept copy-pasting code between ChatGPT's web UI and my editor, so I built WTAgent — a free, open-source MIT CLI that turns your ChatGPT Web account including Pro into a Codex-style local coding agent, and your Claude Web into a Claude Code-style agent. WTAgent runs in your terminal, drives a dedicated Chrome profile where you're signed into your web AI, and closes the loop locally: No model API key, no MCP server, no tunnel — it uses the web subscription you already pay for. wtagent --model claude or deepseek / gemini / grok / kimi / glm switches the web AI driving the loop. npm i -g wtagent wtagent Works on macOS, Linux and Windows WSL2 . Node 20.17+ and Chrome/Chromium required. Independent CLI, not an official Codex or Claude Code client. Your code/outputs sent to the chat go to the provider, so follow their terms; local policy checks aren't a sandbox. Feedback welcome — especially first-run issues
