Fast-booting VMs for Any Code
Fly Machines are the compute behind apps on Fly.io. Here's what you get:

- Deploy any containerized application
- Global private networking between your machines
- Autoscaling and pay-as-you-go pricing
- Automatic health checks and monitoring
Full-service Compute at Serverless Speeds
Fly Machines use Firecracker: the same fast-launching microVMs that back AWS Lambda. Get sub-second starts and stops with full VM control.
Your Own Secure Private Network
Fly Machines live on a global secure private network that you get by default, allowing you to connect to your apps publicly or privately with granular routing.
Best of all? No matter where you deploy your Machines, we automatically route requests to the ones closest to your users.
Pay-As-You-Go Pricing
Only pay for what you use. Fly Machines scale from small apps to massive workloads with transparent, per-second billing.
Deploy Anywhere with Fly Machines
Deploy your applications globally with Fly Machines. Scale fast, run anywhere.
