i use https://github.com/vrtmrz/obsidian-livesync and self-host a couchdb instance for it...
this looks like it might be a bit cleaner once it's all fleshed out...
I just setup Obsidian a couple days ago and have been using https://github.com/vrtmrz/obsidian-livesync which seems to work ok. I'm curious if SyncThing would be preferable. How does it handle conflicts? How often does it sync? Does it drain the battery on mobile if it syncs too often?
There is also another one: using the self-hosted LiveSync plugin.[0] This uses CouchDB.
