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 App

Public 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.

  • Get Right in Your Users’ Faces

    Deploy in 35 regions, from Sydney to São Paulo, for sub-100ms response times and native-app feel no matter where your users are.

  • Fork Off VMs Like They’re Processes

    Fly Machines start fast enough to handle HTTP requests, run only when you need them, and scale into tens of thousands of instances.

  • Ship GPU-Boosted Models

    From LLMs to inferencing, hardware acceleration with the same developer experience as a simple CRUD app.

  • Built for Distributed Systems

    Clustered databases like Cockroach, globally-distributed Postgres, and modern RPC systems like Elixir FLAME, no Terraform required.

Support By Developers For Developers

Paid plans include a team of actual engineers (not chatbots) who themselves ship code on our platform. Emergency support and guaranteed response times available.
