machine0 launches a CLI that provisions persistent NixOS and Ubuntu VMs from the terminal. Users can spin up instances with 1‑60 vCPU, up to 240 GB RAM, optional GPUs, static IPs and HTTPS endpoints. VMs stay on with 99.99% uptime and are billed per minute, starting at $0.013 per hour. All images are open source and include pre‑installed tools like Docker and Node.

The tool shines for NixOS because it treats the OS as code via flakes. A flake.nix and lockfile guarantee reproducible builds; running `nixos-rebuild switch` yields identical systems. machine0’s CLI can provision from a flake or an Ansible playbook, create snapshots, and clone them, enabling developers to audit configurations and roll back with a single command. Snapshots can be named and restored instantly.

Pricing scales with resources; a small 1 vCPU/1 GB VM costs about $0.013 per hour, while large configurations reach $3.71 per hour. Images are open source, and each VM receives a public address like `<name>.mac0.io`. The service targets long‑running tasks, CI pipelines, and autonomous agents that need isolated, reproducible environments without managing underlying hardware.
