I built multAIplayer to let trusted teams work together around a shared local Codex session. The free, open-source product brings the conversation, code, tools, and decisions into one project room.
Teammates can follow the conversation, propose the next turn, inspect structured progress, and review changes. Room-scoped files, diffs, terminals, browser previews, Git, and GitHub workflows keep the work connected to its context.
The hosting model is explicit: one active host supplies the project, local tools, credentials, and Codex account. A verified member can take over through an explicit handoff. Desktop and CLI clients support the collaboration workflow.
