I'm currently running a Synology Notestation with around 8 clients and while it mostly works, sometimes images don't load correctly(or doesn't at all) and has failed on me one too many times.
I'm looking for another notes app similar to DS notes.
1- Rich Text Editor
2- Self hosted
3- Has multiple users enabled
4- Native Android app
Nice to have:
1- offline mode
2- FOSS
3- Has an active community
I host files for my entire family and they rely on notes for all their important documents. So it has to be simple to use.
I have tried benotes, but not having a Native Android app makes it hard for normies to use it. I also tried Joplin, but it's single user only.
Joplin can be a multi-user solution as well. I use Joplin with Nextcloud. If you don't want to share notes just use Joplin and every user can use the same nextcloud instance, but different user accounts, to save their notes. If you want to share all the notes, all the users can synchronise with the same Nextcloud user. You can make different notebooks for different users. All the users, however, can see and edit notes. Joplin cannot be a solution if you want to share some notes. It is either all, or none.
Logseq can be another solution, with the same technique. However, you can use git to synchronise different databases, where one database is used in shared notes and personal databases for non-shared notes. I host my own Gitea (will soon shift to forgejo) to synchronise my Logseq databases.
Just set up a Joplin cloud server for me and my buddy to do a writing project. It's the most robust open source solution I could find for the situation and so far it is meeting every expectation.
