When we started building Fly, we figured it was too late to "make SSL easy and the customers will come". Lets Encrypt changed the world, and we knew many companies rolling their own SSL support with nginx, Traefik, etc, etc. It seemed like a solved problem.
It turns out that SSL is still a pain, particularly companies with lots of hostnames pointed at them ... anyone hosting apps/content on behalf of their own customers. Distributing certificates, keeping them renewed, and — most of all‚ making https fast is still hard. Devs can solve the basic problem in a week or so with a proxy, but then it sits, and no one feels very comfy with untouched infrastructure. And it's usually something distracting devs from more important work that's core to their own customers.
So this is our way of solving that problem. We can handle any number of hostnames for applications, devs can spend more timeon what makes their apps special. It's a relatively "simple" use of what we've built, but solves a really fundamental problem for a many companies. It's the most fun thing we've discovered this year.
So, if you're building an app, and serve stuff on behalf of your users, we can make your life easier:
