QM, Y Combinator's Open-Source Agent Harness, Now Deploys in One Click on DigitalOcean

Y Combinator built QM, a multiplayer agent harness for Slack and the web, to run agents across its own teams, from accounting and legal to engineering. In July, YC open-sourced it so any startup could do the same. Starting today, DigitalOcean offers the first one-click deployment for QM from the DigitalOcean Marketplace.

“We made QM open source so companies can own the agents that run their business. DigitalOcean makes it easy to get started. In one click, a team has QM running with sandboxes, inference, data and storage already in place, and the time they’d have spent on setup goes into building their company,” said Joshua France, Head of YC Labs, Y Combinator.

What one click sets up

Running QM has meant assembling a stack across providers. The DigitalOcean Marketplace deployment sets up all of it at once, on one bill:

• A Droplet for QM’s core service
• Managed Agents for isolated sandboxes
• Serverless Inference, with no extra API key
• Managed PostgreSQL for sessions, memory and the job queue
• Spaces for files and snapshots

Open by design

QM lets each team choose its harness and model (e.g. Pi, OpenCode, Codex, or Claude Code), and it runs in a range of environments. DigitalOcean contributed Managed Agents to QM as a built-in sandbox option available to QM users on supported versions.

“Y Combinator and DigitalOcean are working together to bring open intelligence to YC founders. With QM on DigitalOcean, startups can begin on one complete, open platform, choosing their models, harnesses, and data and running them on infrastructure they control,” said Paddy Srinivasan, CEO of DigitalOcean. “We want DigitalOcean to be the easiest place to run QM, and we’re investing in YC founders so they can get the most out of it.”
