Show HN: machine0 – Persistent NixOS VMs You Control from the CLI

A shiny new Hacker News launch just dropped, and the crowd is already doing what it does best: half applause, half existential spiral. machine0 is pitching always-on online computers you control from the command line, with fixed internet addresses, pay-by-the-minute pricing, and the option to pause them when you’re done. The big sell is simple: set up your machine once, recreate it reliably, and avoid the usual “why is this server acting weird now?” chaos. It also comes loaded with popular developer tools and even supports giant AI-friendly graphics chips for people with very expensive ambitions.

But the comments quickly turned into a classic tech soap opera. One fan said the extra Nix support is a huge value add, then immediately delivered the nervous side-eye: what happens if you ever want to leave and move to a giant cloud provider like Amazon? That single comment basically captured the whole mood—love the convenience, fear the lock-in. Another commenter skipped the praise and went straight into the deep-end question: if someone manually messes with a machine, how do you detect the drift, reset it, and make sure backups play nicely? Translation for normal people: “Cool demo, but what happens when real life gets messy?”

Still, the hype squad showed up. One user said they’re already using it for AI agents and web apps and called it super easy. Another practically turned the thread into a philosophical manifesto about how this approach is far better than most ways of shipping Linux machines. So yes, the launch got cheers—but the real entertainment was the community doing its favorite dance: ‘this is amazing’ mixed with ‘tell me exactly how it breaks.’
