Y Combinator Open-Sources QM: Company-Grade Multi-Person Collaborative Agent Workspace
On July 31, 2026, Y Combinator open-sourced its internal multi-agent framework QM (Quartermaster) under the MIT license, and it quickly gained over 10,000 stars on GitHub. QM is a work-agent infrastructure for entire companies, supporting both Slack and Web terminals. Each employee and channel has isolated memory, sandboxes and permissions, and can switch Harness among Pi, OpenCode, Codex and Claude Code. This article sorts out its architecture, Strict/Auto/Dangerous security policies and qm init self-hosted deployment method, for teams evaluating enterprise-level agent operating systems for reference.

This article outlines its architecture, positioning differences from OpenClaw and Hermes, deployment and security strategies, and reminds readers that it is still an early-stage experiment.
