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.
https://notion.so It’s a web-based editor with a good android app. Has basic formatting, plugins/integrations, and dark mode. It’s free for individual use cases. Has some nice paid features for collaboration and business use cases, though the free plan still allows sharing and concurrent editing.
E: noticed this is in self hosted after posting. Maybe not what you’re looking for, but it’s a good service if you’re ok with that.
My only problem with them is the android app, while it has nice features it’s soo slow that even on flagship phones it is hard to use, and when you have multiple accounts switching between them is awful, either the files won’t load or it won’t refresh the interface at all. I usually switch the workspace and then restart the app. Sometimes I can’t open the subfiles of a file until I restart the app and wait for it to load.
I think the reason for that is touch screen, it is only good for social media. I use Google Keep on Android because it is fast and later copy the notes to Notion.
Idk, from what I heard the iOS version of the app is really performant and optimized.
Wish there was a self-hosted version of notion with all the same features
The closest is nextcloud collectives, tables, tasks and deck
