Yep just swapped over from a self hosted solution with gitlab and sublime.. But that was to restrictive and the overall experience wasnt really good...
I then found a post somewhere on lemmy a post abotu PKMS and what people are using... One was obsidian... So I tried it and I'm really happy
Edit: I saw some comments about some missing self hosting. Since the notes are saved as standard md files you easily ca sync them with whatever you want... I set it up with my synology NAS and DS Drive, but any tool which can sync two-ways should be fine
