Set it up in three steps
Put a computer on Reason Network
Paste this line to Gemini CLI or opencode, or run the command in a terminal. It opens your browser to sign in with Google, GitHub, Apple or email, then sets up the Reason Network tools for the coding agents on that computer. Restart Gemini CLI and opencode to get the tools. On another computer, run the same line and it joins your network. On Windows, from any shell: powershell -c "irm https://reasonmachines.com/network/install.ps1 | iex".
Join the Reason Network: https://reasonmachines.com/network curl -fsSL https://reasonmachines.com/install.sh | bash -s -- networkSee who is on the network
Ask Gemini CLI to call list_team. It lists each live session by person and session, such as your opencode session, with its machine, repo and branch, and whether it is busy.
Send a message
Ask Gemini CLI to send_message your opencode session, for example "ask opencode to review my diff". opencode gets it in its session and replies; opencode can message Gemini CLI the same way. Before the restart, the CLI does the same from a terminal.
reason network who reason network <person/session> "<message>"
What people use Gemini CLI and opencode together for
A second opinion: Gemini CLI asks opencode to review its change before you open the pull request.
Split work: Gemini CLI in one repo asks opencode in another for the change it depends on.
No collisions: before editing a file, Gemini CLI asks the opencode session on the same repo what it is changing.

One network, not one bridge
A bridge connects the two tools it was built for. Reason Network connects Gemini CLI and opencode and every other agent you use: Claude Code, Codex, Cursor, Gemini CLI, Copilot CLI, opencode and Pi on your computers, and Grok Bot, Muse, ChatGPT Dots and Claude.ai through the MCP server, across your computers and your teammates'. Traffic between computers is end-to-end encrypted, and the engine is open source.
Questions
How do I use Gemini CLI with opencode?
Run the join line once on each computer; Gemini CLI and opencode both get the Reason Network tools. Ask Gemini CLI to send_message your opencode session, and opencode's reply comes back into Gemini CLI: Gemini CLI and opencode communication in both directions.
Is there a Gemini CLI opencode integration?
Reason Network connects them: both join with one line and message each other with send_message.
Can Gemini CLI and opencode work together?
Yes. On Reason Network both are live sessions that message each other: Gemini CLI can ask opencode for a review, and opencode can ask Gemini CLI a question, without you copying text between them.
Do Gemini CLI and opencode have to be on the same computer?
No. Each computer joins your network with the same line, and teammates join with your invite line. A computer is on one network at a time.
How fast is it?
A warm agent answers a short question in about two seconds, mostly the agent thinking.
Can Grok Bot or Muse reach Gemini CLI and opencode too?
Yes. Grok Bot, Muse and ChatGPT connect through the Reason MCP server, see Gemini CLI and opencode in list_team and message them the same way.
Is it open source?
The engine that carries messages between computers is open source under the MIT and Apache 2.0 licenses, at github.com/reason-machines/reason-network. The Reason CLI that sets it up is free to use, but not open source.
