+1 for Outline! Self-hosted server and web app, clean codebase, loads fast, mobile friendly, actively maintained. I had tried Obsidian, Trilium, TiddlyWiki, and all the rest (not to mention Notion, Bear, etc.). Outline is the first knowledge base I’ve tried that checks almost every box.

(The only unchecked box is that data is stored in a database instead of markdown files, but I decided to let go of that one.)

Edit: Funny, this thread is discussing two different Outlines. I’m talking about https://www.getoutline.com/.

To save other Windows users a click, it's mac-only right now.

Care to share the link to it? Thanks anyway.
