QM is an open-source multiplayer agent harness giving each employee an isolated workspace with scoped memory, files, and permissions while supporting collaboration in Slack channels and a web UI.

The core is vendor-agnostic (drives Pi, OpenCode, Codex, or Claude Code), built on TypeScript/Node with Fastify and Postgres, and deploys to Fly or AWS via a CLI. Security uses three postures (Strict, Auto, Dangerous) with a fixed command policy, and the agent operates under the end-user's own credentials with full audit trails.
