A small macOS (13+) menu bar app for managing Codex model provider configurations.
The app helps you add, edit, and switch between Codex providers such as OpenAI, OpenRouter, DeepSeek, or other OpenAI-compatible services. It writes the selected model and provider settings to ~/.codex/config.toml, stores app data in ~/.codex/model-switcher.json, and can manage provider API keys and saved OpenAI account credentials.
- Add, edit, and delete custom model providers.
- Manage multiple models per provider.
- Switch the active Codex model from the menu bar.
- Manage multiple OpenAI accounts.
- Write Codex config updates automatically.
- Built-in compatibility proxy for Chat Completions providers (ie Deekseek).
- Keep the app menu-bar only, without a Dock icon.
Codex may need to be restarted after changing provider, model, or OpenAI account settings.
API keys and OpenAI credentials are sensitive. Treat files under ~/.codex/ like secrets.
Codex now uses OpenAI's Responses API for custom providers and deprecated wire_api = "chat". For providers that only support Chat Completions, enable the built-in compatibility proxy to translate Codex /responses calls to /chat/completions.
