Up to now I've been using Simplenote, which has a Linux client (but also Android & iOS) & supports live collaboration on notes. However, Simplenote hasn't had a meaningful update for a long time, & it's recently been behaving strangely, e.g. notes undeleting themselves, line duplications & undeletions.
Can anyone recommend an alternative? Spinning up an ownCloud/nextcloud instance just to use Joplin feels a little overkill. I stumbled across turtl, but the project looks abandoned.
Unfortunately with iOS you are stuck with Obsidian Sync because Syncthing does not work because of the permission model. Otherwise I prefer Obsidian over Joplin for the above mentioned reasons and nice extension ecosystem. It's easy to get your files out of Obsidian, no vendor lock-in
Möbius sync is a Syncthing client for iOS. I have the same setup as Foss Is Fun and everything works very well
