There's a good chance we're about to freak you out

Whatever your app is, from Django to Elixir/Phoenix, it's probably about to run on Fly.io in just two quick steps. Ready… set…

Step 1

Install Flyctl

Follow these instructions to install flyctl, our intrepid command-line interface. It's 100% open-source if you're squeamish about this stuff. 

> Install flyctl on GNU/Linux
$ curl -L https://fly.io/install.sh | sh

Step 2

Launch your app

Run flyctl launch and follow the instructions. That's all there is to it. 

> Ship a Docker image
$ fly launch
