FWIW: sr.ht is pretty cool, has a nice no-nonsense UI, and the build system is really simple and powerful. It's not "done" but it works and is going in the right direction. It's a very nice corner of the Internet. I've been using it for personal repos and I'm really happy.
I support sourcehut, because I would like to see it evolve, and hopefully keep the no-nonsense UI approach. Having a nontrivial site with a usable interface running without JS in 2019 is beautiful on its own.
