Hopefully when I make some money I can move to a hosted setup where I can control it all.

https://www.certera.io fails the certificate check.
It's a good example of the difficulty of getting TLS perfectly right.
In theory this set up is fine; the default behavior of all the browsers when typing "www.certera.io" is to interpret it as a request for http://www.certera.io.
But if the client has anything in place that automatically upgrades http to https before submitting the request, you're going to need a valid cert for the www subdomain in place or you'll throw a cert error before reaching the redirect.
Even if your site omits the www subdomain in production (as certera does), a lot of users will just type it in anyway. So, you better be ready to handle that request via https.
Any thoughts on the license? How is it working? Why did you pick that? I like that type of license, but it's not very common. Drone does it too, but I haven't seen many others. You don't have to answer if you don't want to, but it's nice to see people deviating from standard licenses like GPL and MIT since I feel like those make it too easy for large businesses to take advantage of small projects.
Your licensing and attribution pages look like a lot of thought went into it, so you probably have some decent insight.
I haven't been marketing at all, and I just recently finished the first stable release, so the jury is still out on whether this is all a good idea or not!
The docs are based on ReadTheDocs, but settled on a single file layout instead of having multiple pages.
