Superserve

What is Superserve?

Traditional cloud infrastructure was built to run a single app for many users. Agents work differently. Each one needs its own isolated machine to write software on the fly, run tools and act on its own for hours or weeks. And everything it produces has to persist between sessions. Superserve gives every agent and RL rollout its own virtual machine that starts in under 50ms. Machines start from templates with your repo and dependencies already loaded, pause with memory and files intact at zero compute cost, and resume or fork from that exact state. You can run docker, databases, browsers or any services on these VMs. API keys stay outside the machine and egress rules control what agents can reach. For teams building coding agents, autonomous workers, or eval and training environments, that means elastic infrastructure with no servers or warm pools to manage, and control over what every agent can reach and which credentials it can see. We run over 100K machines (as of Oct 2026) every week for world-class teams, including Lindy, and Y Combinator itself.
