How to get it?

The easy way

Just head to the Aseprite website page, purchase it for 15$ and download it through steam, or as binary from the page.

The hard way

Aseprite costs 15$ when purchasing the precompiled version, but if you look carefully at the FAQ, you can find out that if you compile it yourself from the freely available source code, you can then use it for whatever you want. So, head over to Aseprite repo for instructions on how to compile it! I promise you you won't be disappointed!
