CodexHost open-sources, integrating Claude Code, Pi, and Grok into the Codex desktop.

Beating AI Express News: Open-source project CodexHost has transformed Codex Desktop into a multi-agent workspace. It currently supports Codex, Claude Code, Pi, Oh My Pi, Grok Build, and DeepSeek Harness, allowing users to create and manage sessions for different agents within a single window. Codex Desktop is solely responsible for the unified interface, while each agent runs on its own harness—for example, Claude Code continues to use Agent SDK/CLI, and Pi retains its own RPC. CodexHost integrates these agents into Codex, preserving native capabilities such as tool calls, code diffs, approvals, and queries. Different agents can also assign tasks to each other: when Codex is writing code, users can separately launch Claude Code for code review, enabling parallel work between the two, after which Codex processes the results. This means multiple coding agents can be scheduled simultaneously within one Codex window. Installing CodexHost does not modify the official Codex or replace Codex CLI. Directly opening Codex Desktop or running Codex CLI in daily use bypasses CodexHost, which only takes effect when launched via CodexHost.
