SiYuan, Privacy First, Affero GPL, self-hosted PKMS written in ts and go

I came across this project a while back and adopted it for my personal Personal Knowledge Management System/PKMS.

I've bounced around a few PKMS in the past, eventually settling on Obsidian but later moving to Logseq in an effort to avoid relying on closed source tooling. Then recently I discovered this project and I've been beyond impressed.

The desktop and mobile apps work very well and to be entirely honest are way more polished than I've come to expect from a FOSS PKMS, it's full featured with more or less everything I could want. It has a built in git-like VCS, it has integrated rendering for Mermaid, Plantuml, etc, and what I've personally found most interesting is it supports representing your notes as structured data that you can query with SQL.

My one gripe is the english docs are pretty sparse but otherwise I've had a phenominal time with SiYuan and I thought HN might find it interesting.
