Uptime: A Cloud Provider Simulator
Build a cloud provider from a garage to a hyperscaler.
You do not operate this datacenter from a spreadsheet. You walk through it.
Uptime is a first-person infrastructure simulation about building and operating a cloud provider from the hardware up. Servers, switches, cables, ports, power, services, customers, and failures are active parts of one deterministic system.
Early Access is available now
Play on Windows, macOS, and Linux. A free demo covers the opening chapter.
Choose your path
🚀 Start in the garage
Learn the controls, assemble your first stack, and sign your first customer.
🧠 Understand the simulation
Learn how Uptime models services, networks, power, and reliability.
🧰 Look up hardware
Browse hosts, switches, gateways, appliances, racks, and cabling.
🚨 Respond to incidents
Diagnose failures with checks grounded in the simulation.
📟 Use the Companion
Observe, correlate, and prioritize the state of a running simulation.
The whole stack is yours
- Hands-on hardware: buy, carry, rack, power, and cable every device.
- A real cloud to run: operate VMs, storage, databases, Kubernetes, and load balancers.
- Customers as commitments: revenue follows reliability, capacity fit, and reputation.
- A simulation that pushes back: topology, fault domains, heat, wear, and incidents matter.
- Approachable but honest: player-friendly explanations and engineering detail describe the same underlying model.
