What each one is
codex-chatgpt-web
This is a launcher app that connects Codex, a coding assistant, to the ChatGPT Web models available on your own ChatGPT account. Messages run through your signed-in ChatGPT web session, so they count against that account's ChatGPT limits rather than Codex quota. An optional Full harness mode uses MCP to let ChatGPT work with the current task's files, terminal, and tools, with approvals.
wechat-bot
This project is a bot that receives messages from chat apps (WeChat, Lark, Telegram, WhatsApp) and passes them to AI services such as ChatGPT, Claude, DeepSeek, or a local Ollama model, then sends the AI's reply back. It can also read local WeChat chats and contacts to run statistics or AI analysis on a group or a friend. It is built on the Wechaty library and requires you to configure your own API keys or local models.

Strengths
codex-chatgpt-web
- The README says the app includes its own browser and runtime, so no separate Chrome, Node, or Bun install is needed
- Keeps the Codex interface, tasks, images, and streaming, per the README
- Full harness connects through an outbound tunnel, so it does not open an inbound port or require router forwarding
wechat-bot
- Supports many AI providers, including OpenAI-compatible APIs and local Ollama
- Covers several chat platforms (WeChat, Lark, Telegram, WhatsApp) under one command set
- Uses an MIT license and has a large public user base on GitHub
Not ideal for
codex-chatgpt-web
- Teams that need a supported, stable API: the README says this is unofficial browser automation, not an OpenAI API, and UI changes can break it
- Anyone sharing a computer or unable to protect the launcher's login profile, since browser state is a sensitive login artifact
- Users who need platforms beyond macOS 13+, Windows x64, and Linux x64, which are the documented release targets
wechat-bot
- People who need a safe, officially supported WeChat integration: the README warns that WeChat Web protocols can trigger warnings or bans
- Non-technical users, since setup involves editing a .env file and running terminal commands
- Anyone who wants a polished consumer app with no configuration
Trade-offs
codex-chatgpt-web
- Unofficial browser automation: selector or UI changes on ChatGPT's side can break it, and the README says drift fails explicitly rather than silently switching
- Usage limits and context windows depend on your account type and selected effort, and are described in a linked discussion rather than fixed numbers
- Builds are not yet platform-signed, so Gatekeeper or SmartScreen may show warnings
wechat-bot
- WeChat account risk: the README notes the default protocol can lead to warnings or bans, and the padlocal protocol is no longer maintained
- Some AI services are paid; ChatGPT is described as a paid service requiring billing
- Requires Node.js 18 or newer and manual .env configuration; the README is truncated and some features are described only briefly
