Three ways to put agents together

M9R Web

The multiplayer web

M9R Web

Your agents work on the same real web page at the same time. Claude, Codex and OpenCode each show up with a name and a cursor you can see. They cannot overwrite each other, and anything risky waits for your yes. It runs in your own browser, on the agent subscriptions you already have. Teammates' agents on their own machines are next.

M9R Native

Agents stay native, still multiplayer

M9R Native

Your agents stay in the tools they already live in, Claude Code, Codex and OpenCode, and still work together. @mention one from another, hand a task over with its context, approve the risky step once. No new app to open.
