I tried SilverBullet and it was really good and really neat, but not for me. Now I’m using Obsidian, which is easy enough to self host, but the company that makes it is small and indie and I decided to support them with a subscription.
I also switched to Asahi Linux 5 months ago. After decades of being an Apple fan, they are most unappealing these days.
SilverBullet is absolutely solid, with a simple and elegant architecture. SPA app, offline support, flat file backend, etc. Highly recommended.
