Currently I’m using Joplin with Syncthing-backed file system synchronization. I’m pretty pleased with it, as I do like tagging- and Markdown-based systems.
I plan to upgrade to server-based synchronization, but before doing that, however, I wanted to see what other people are using.
Edit: So far I see a slight favor towards Joplin and Logseq, but I totally didn’t expect (and appreciate) getting so many different answers.
I’ve been using Joplin server in a docker container exposed via Traefik for almost 2 years now and I use it daily and have had no issues at all.
Highly recommend this setup, and docker+Traefik for pretty much everything.
