Scalable Full Stack
Without the Cortisol
Over 3 million apps have launched on Fly.io, boosted by global Anycast load-balancing, zero-configuration private networking, hardware isolation, and instant WireGuard VPN connections. Push-button deployments that scale to thousands of instances.
Speedrun Your AppPublic Cloud Infrastructure. Modern Platform Endorphins.
The most flexible and powerful compute platform on any public cloud. Fly Machines are hardware-virtualized containers, running on our own hardware, that launch instantly and run exactly as long as you want them to — for a single HTTP request, or for weeks of uptime.
