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.
Joplin. Obsidian is not open source, doesn’t have native self hosting and it gets complicated. Joplin is very simple and just works. Although, it stores the notes in a hashed database, so you can’t edit raw files without Joplin
Trilium for the same reasons, but the featureset of Trilium is more like Obsidian.
Trillium was originally created to be an open source replacement for Roam Research. It’s similarities to Obsidian are purely coincidental, probably because Obsidian is designed to be a cross between Roam and Evernote.
Problem with Joplin: The raw files are randomly named so you can’t easily find a specific note
That’s not even the bigger problem. I found the desktop ui very clunky. There were too many papercuts for me to keep using joplin. However, its TUI and mobile app are excellent.
