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.
Logseq, it’s a lot like Obsidian as it also has knowledge graphs, tags, is markdown-based and self-hostable but, in contrast to Obsidian, it’s fully open source
Much prefer Logseq as well.
Checking out Logseq now. I switched to Obsidian a few months ago and have been really liking it. Was time to switch it up from org-mode after YEARS of using it
