Welcome to the Fly Documentation. There's a lot here so we have guides to speed you to the information you need.

In the Overview

This is the Overview section. Here you will find:

  • Introduction: The Introduction explains what Fly is, why we built it and what it can do for you.
  • Speedrun: The Speedrun is the bare essentials of deploying an App on Fly in the fewest possible steps.
  • Hands-On: The Hands-On Section is a more leisurely step-by-step introduction to the same process: deploying an App on Fly.

Beyond the Overview section, there are four major sections of the documentation.

Quickstart Guides

The Quickstart guides go deeper into building and deploying apps on Fly, including specific guides for Go, Node, Ruby and Deno, and creating a static website. There's also a quick guide on how to work with your deployed Apps.

Guides and Examples

Our Guides and Examples Section is a library of both full examples and detailed guides on how to configure and run particular apps or use Fly for specific applications.

Fly Reference

The Reference section is the heart of the documentation with both essential reference content for Fly's command-line tool Flyctl and reference material for everything from Fly's architecture and scaling to Redis on Fly and managing secrets.

About Fly

The About section has all the essential things you need to know about Fly as a service: pricing, security, support, privacy, and terms.
