Fly Machines Has a Free API: Deploy Containers Globally With Sub-Second Boot Times

Fly Machines is Fly.io's API for launching and managing lightweight VMs (microVMs) that start in under 300ms and run in 35+ regions worldwide. Why Fly Machines Matters Traditional cloud VMs take 30-60 seconds to boot. Fly Machines boot in under 300ms using Firecracker microVMs — the same tech AWS Lambda uses internally. You get VM-level isolation with serverless-level speed. What you get for free: Firecracker microVMs that boot in <300ms Deploy to 35+ regions worldwide Scale to zero: machines stop when idle, restart on request Direct REST API for programmatic control Built-in Anycast networking (automatic global load balancing) Persistent volumes for stateful workloads Free tier: 3 shared VMs, 160GB bandwidth Quick Start # Install flyctl curl -fsSL https://fly.io/install.sh | sh # Login fly auth login # Launch app from Dockerfile fly launch # Deploy fly deploy # Scale to multiple regions fly scale count 3 --region iad,lhr,nrt Machines REST API # Create a machine via API curl -X POST "h
