hcom is a command-line tool that connects different AI coding agents so they can talk to each other. You run it in front of your agent, and then agents can send messages, watch what others are doing, and even start new agents. It works with many popular AI tools like Claude Code, Codex, and Gemini.
hcom is a lightweight CLI tool that enables AI agents to communicate, observe, and orchestrate each other across terminals. It integrates seamlessly with popular AI coding assistants such as Claude Code, Codex, Gemini, OpenCode, Kilo Code, Pi, Antigravity, Cursor, Kimi, and Copilot without requiring changes to how you use them. Agents can message each other in real-time, observe transcripts and file edits, subscribe to events, and spawn, fork, resume, or kill each other. The tool uses a local SQLite database to record activity and deliver messages. It supports cross-device communication via an MQTT relay with end-to-end encryption. hcom is a single Rust binary with no background services, making it easy to install and use. It is ideal for coordinating pipelines, running different AI CLIs as subagents, or simply replacing copy-paste workflows.

The setup section provides repository-level starting guidance, not a guarantee of an independently verified installation. Check the official README and release notes.
Agents can execute arbitrary commands on your system; only use with trusted agents. Cross-device relay uses end-to-end encryption, but treat join tokens like API keys.
