Ask HN: Which self-hosted solutions are you using?

New top story on Hacker News: Ask HN: Which self-hosted solutions are you using? I came across Perkeep[1] project today. I know some other self-hosted solutions like Rocket chat[2](Slack alternative), Redmine[3](Project management) etc. Curious what other self-hosted are there and which one you are using?
