I've recently installed nodeBB, migrating out of the bbPress forums. The forum is located at TechMesto, just if you'd wanna include it in the original post.
Spent days on discourse, but I found nodeBB having a better community and plugin support. Plus the docker based install of Discourse is a big mess. The importer plugin for nodeBB does wonders and after some support from developer, helped me migrade pretty much everything from my bbPress over to nodeBB.
Thanks a lot to everybody involved with this project.
