GitLab. I know it has it's problems in hosted form, but I've stood GitLab up on a Linode about a year ago and have had zero problems with it. Since then, I've grown increasingly dependent on it, starting to use GitLab CI for some basic automation around things like my blog, or managing my Chef environment. I started out by standing it up as a test, and am considering strongly reducing my GitHub footprint in favor of it if only for the "free" private repos (yeah, I'm paying for a server, so it's not free). I think having GitLab stood up in my life will actually open me up to other stuff that I hope to find in this list, too. Does Plex count? If so, Plex. I love it, and don't remember how I lived without it.
