Fly Machines are fast-launching VMs; they can be started and stopped at subsecond speeds. We give you control of your Machine count and each Machine’s lifecycle, resources, and region placement with a simple REST API or flyctl commands.

Introduction to Fly Machines: Learn whether you need low-level Machine control. Find out more about the lifecycle of Fly Machines and about scaling and placement.
Machines API: A simple and fast REST API for full control over our fast-launching Machines.
Run a New Machine or Update a Machine with flyctl: Configure, build, and start new Machines with a single command or update some or all of a Machine’s configuration.

On the other hand, try Fly Launch if you prefer easy app-wide configuration and containerized deployment for your app.
