cccc vs agent-bridge
Coding-agent collaboration tools compared
cccc and agent-bridge help coding agents collaborate, but serve different needs. cccc provides a broader coordination layer for persistent groups, while agent-bridge focuses on relaying messages between Claude Code and Codex in a local workflow.
cccc: Coordinate Coding Agents as a Persistent Group Chat
CCCC is a local-first, Rust-based coordinator for running coding agents as a persistent team across runtimes, machines, and trusted groups. It provides durable message history, delivery tracking, and Web and IM access, with installers for Linux, Apple Silicon macOS, and Windows.
agent-bridge: Connect Claude Code and Codex for Collaboration
AgentBridge relays messages between Claude Code and Codex in a shared local workflow, enabling in-session reviews and task handoffs. It is designed for developers who already use both tools and want them to coordinate without manual copy-paste.

Key differences
- cccc coordinates supported runtimes in groups with durable message history, delivery and reply tracking, and task and context stores; agent-bridge relays messages between Claude Code and Codex.
- cccc offers a daemon-controlled Web UI, CLI, MCP tools, and supported chat-platform bridges; agent-bridge centers on a local daemon connecting Claude’s MCP channel to Codex’s app-server.
- cccc is written in Rust and licensed under Apache-2.0; agent-bridge is written in TypeScript and licensed under MIT.
- cccc supports group connections across instances with explicit access boundaries; agent-bridge supports multiple project pairs on one machine, with one Codex thread and one foreground Claude connection per pair.
- cccc lists Linux x86-64, Apple Silicon macOS, and Windows x86-64 support; agent-bridge requires Bun and does not officially support Windows.
- cccc is suited to teams coordinating persistent, mixed-runtime workflows; agent-bridge targets developers who already use Claude Code and Codex and want peer collaboration.
Choose cccc if you…
- need persistent group coordination across supported agent runtimes.
- want durable delivery, read, reply, and task status in a shared history.
- need Web, CLI, MCP, or chat-platform controls for ongoing group operations.
Choose agent-bridge if you…
- want Claude Code and Codex to relay messages and review each other’s work.
- need a local bridge for handoffs between those two tools without manual copy-paste.
- want to manage multiple Claude Code and Codex project pairs on one machine.
