Codex Host
Codex Host is a desktop utility that allows users to run multiple AI coding assistants natively within the Codex Desktop interface.
Codex Host acts as an integration layer that enables multiple AI coding agents to operate within the existing Codex Desktop interface. Instead of switching between different applications, users can access Pi, Claude Code, Grok Build, and other coding assistants from the same window. The tool extends Codex Desktop via CDP and Electron Inspector rather than creating a new chat interface. It allows for delegation of tasks between different models by using a specific command prefix in the chat input. Each task operates in its own native session, which keeps conversation history organized and viewable. This architecture supports remote development, allowing users to drive AI tools on a remote machine while maintaining a local user interface.
