I’ve been using Obsidian for a long time. I enjoy it and all of its extensions. However setting up the app and syncthing on all of my systems gets irritating.
Any way, after a little looking around, I found Trillium notes. It doesn’t quite have all the extensions, but is easier to setup. Give it a look, see what you think
FWIW I use foam. It is a visual code extension so you piggyback on all Visual code features and extensions (e.g. git, md lint, etc). And I sync with my self hosted gitea. It doesn’t have a mobile app but I use obsidian with the obsidian git plugin
