For my knowledge base, I use VS Code with Markdown Memo, which supports back links and easy link creation. Free.
Ultimately it’s all just a bunch of Markdown files with mermaid diagrams and LaTeX equations. It’s so simple.

https://dendron.so is an "Obsidian" as a VS Code extension.
Turning markdown into an interactive kanban is especially powerful, and more extensions are being added all the time.
I am going to check out Joplin soon, though. Obsidian could be a little friendlier and come with a couple more batteries for someone like me.
