I do almost the same thing as a(n unpaid) hobby that I do as my (paid) job. I’m a software developer who writes open-source software on the side.
I’ve also seen a few of my other hobbies grow into serious industries with real employees. The (hobby) drone industry and the 3D printing industry are quite large and growing (I assume).
Just don’t host it with a USA company.
(Self-promo: https://git.ngni.us/mirrors/Ryujinx is still up, hosted in Canada)
