Coding agents have outgrown the laptop. A session might run four to eight hours debugging a hard issue, and tools like OpenClaw increasingly run around the clock — which is awkward when the agent lives on a machine you need to close. machine0, a Y Combinator Summer 2026 startup, gives those agents a persistent home in the cloud, driven entirely from the CLI.

## What machine0 does

One command — `machine0 new my-vm` — spins up a cloud VM with dedicated CPU, RAM, and optional GPUs, plus a static IP and an HTTPS endpoint. Crucially for agent work, the VMs come with Claude Code, Codex, OpenClaw, Hermes, and tooling like Node, Python, and Docker pre-installed, so an always-on agent has everything it needs from boot. The CLI handles the full lifecycle — provisioning via Nix flakes or Ansible playbooks, plus snapshots to capture and restore state.

## Why it fits the agent era

The pitch is that agent workloads are shifting from ephemeral to always-on, and a laptop is the wrong host for that. machine0 offers a 99.99% uptime SLA across four regions, aiming to be the durable backend where long-running and 24/7 agents actually live. Founded by 2x YC founder Barnaby Malet, it treats “a VM per agent” as a first-class, scriptable primitive.
