Over 3 million appshave launched on Fly.io, leveraging global Anycast load-balancing, zero-config private networking, hardware isolation, and instant WireGuard VPN connections, with push-button deployments scaling to thousands of instances.
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.
Deploy in 35 regions, from Sydney to São Paulo, for sub-100ms response times and native-app feel no matter where your users are.
Fly Machines start fast enough to handle HTTP requests, run only when you need them, and scale into tens of thousands of instances.
From LLMs to inferencing, hardware acceleration with the same developer experience as a simple CRUD app.
Clustered databases like Cockroach, globally-distributed Postgres, and modern RPC systems like Elixir FLAME, no Terraform required.
Paid support packages include a team of actual engineers (not chatbots) who themselves ship code on our platform. Emergency support and guaranteed response times available.
Apps running on Fly Machines are KVM hardware-isolated, built on a memory-safe stack and running directly on our own metal.

Imagine if a server could boot as fast as a serverless function? That's Fly Machines—serverless compute is a trade-off you no longer need to make. Graduate to a full-stack cloud to regain control over your stack & hosting bill.
Functions and apps boot and respond to web requests in 250ms or less with Fly Machines. You decide to keep them running or automatically put them to sleep.
JavaScript, TypeScript, Bun, Deno—whatever your flavor, Fly Launch automatically detects your runtime and generates a VM with everything you need to run your app.
Run workloads that require GPUs or lots of CPUs, memory, and storage in over 30 regions around the world—all interconnected by a private, encrypted WireGuard network that works out of the box.
Build with your favorite framework. No Dockerfile? No problem: our CLI generates containers for most popular frameworks, including Rails, Phoenix, Django, Node, Laravel, and .NET.
Help us build the next public cloud. No, seriously. Is your product something devs can take advantage of to ship better apps? Work with us.
