qm

qm is Y Combinator's own open source answer to running a fleet of AI agents across a team. It's a "multiplayer agent harness for work": every person gets an isolated workspace with personal and shared scopes, you drive it from Slack or a web UI, and it can run background and scheduled agent jobs. This is YC Labs code, not a fan project trading on the name, the release is announced on ycombinator.com and served from qm.ycombinator.com.

The interesting part is the multiplayer framing. Instead of each developer babysitting one agent in a terminal, qm treats agents as shared, always-on coworkers with their own scopes and cron schedules.

For a team already leaning on coding agents, it's a free way to run them coordinated instead of siloed. Solo use works too, but the design clearly targets groups.

The catch is that it's brand new. The commit history is short and the stars arrived fast, which means the code is early and production-readiness is unproven. The pedigree is real and the idea is sharp, but pilot it on non-critical work before you wire it into how your team actually ships.
