Why we exist.

Fyra Labs builds Terra and Ultramarine Linux. We needed servers for that. We couldn't find hosting we'd actually recommend to someone without adding a bunch of caveats, so we started running our own.

Stack is what came out of that. Real hardware, flat pricing, no surprise fees. We charge you for what you use. We don't sell your data, we don't lock you in, and we don't have a "retention team."
