Fly.io

Also called Fly

What is Fly.io?

A platform that deploys applications close to users globally by wrapping Docker containers in secure, lightweight microVMs for extreme performance.

Fly.io transforms standard Docker containers into fast-booting Firecracker microVMs and deploys them across a global network of physical servers. It uses Anycast networking to route users to the geographically closest server, making it ideal for low-latency full-stack edge applications and distributed SQLite databases.

How it relates to Orbit

Orbit’s built-in deploy health covers Vercel and Railway; a Fly.io app still runs through the queue, but its deploys are not tracked in Orbit. See Watch Deploy Health for details.

When you would use it

You deploy to Fly.io when your application demands low-latency global distribution, or when you need the simplicity of a PaaS combined with the control of raw virtual machines.

Common operations

  • Deploying a highly responsive, globally distributed Remix application.
  • Running persistent stateful databases at the edge close to end-users.
