What is hcom?

hcom is an open-source tool that lets AI coding agents communicate with each other across terminals. It supports Claude Code, Codex, Cursor CLI, OpenCode, Kimi and more, so agents can message one another, watch each other's progress and spawn new agents to handle tasks in parallel.

Third-party open-source projects. We are not affiliated with their authors; repositories are provided as-is by their maintainers. Review each project's license, code and security before installing. See our Disclaimer.

Pros: what hcom does well

  • Free and open source
  • Connects many popular coding agents in one channel

Cons: where it falls short

  • Requires setup and CLI familiarity
  • Best suited to technical users

What people use hcom for

  • Letting one coding agent review another agent's work and send it fixes
  • Running different AI command-line tools as each other's subagents, for example Claude Code with Codex
  • Splitting a big task across several agents and collecting their results
  • Waking an agent from a script when another agent goes idle or finishes

How to get started

  1. 1Install it with uv (uv tool install hcom) or Homebrew (brew install aannoo/hcom/hcom).
  2. 2Start each agent with hcom in front, for example hcom claude in one terminal and hcom codex in another.
  3. 3Prompt normally, for example ask one agent to review what the other did.
  4. 4Run hcom on its own to open the dashboard and see every agent's status.

hcom pricing

hcom is free and open source under the MIT licence. You still need your own access to the coding agents you connect, such as Claude Code or Codex. See current prices on hcom's site

hcom FAQ: quick answers

Which coding agents does hcom work with?
Its README lists Claude Code, Codex CLI, Gemini CLI, OpenCode, Cursor CLI, Copilot CLI, Kimi, Pi and several others. Tools without hooks can still join by running hcom start.
Does hcom change how my agents behave normally?
No. Its hooks only switch on when you launch an agent with hcom in front, and you can remove them with hcom hooks remove.
Can agents on different computers talk to each other?
Yes. hcom has a relay option that connects agents across machines. Treat the relay token like a password.
