Things I've actually kept self-hosting for personal use for more than a year:

- Wekan (Trello clone) https://wekan.github.io/

- Taskwarrior + Taskserver (Todo lists) https://taskwarrior.org/

- Syncthing (File sync) https://taskwarrior.org/

- The Lounge (IRC client) https://github.com/thelounge/lounge/

The "Awesome Selfhosted" GitHub repo is a decent place to discover things: https://github.com/Kickball/awesome-selfhosted
