Codex Router
Codex Router is a tool that connects external AI models to the Codex application and CLI for custom code generation workflows.
Codex Router acts as an intermediary, allowing users to route tasks to models such as Anthropic, Kimi, DeepSeek, and xAI within the Codex environment. The router manages provider credentials locally on the user's computer, ensuring they are not exposed. It includes an optional Electron Control Center with a tray application and a macOS desktop widget for managing sessions. The tool supports integrations with client-owned agent sessions like Claude Code, Cursor Agent, and Gemini CLI, while respecting existing official authentication. It provides a guided installation process to configure providers and background services.
