We're developing Saga [0] and we have many users using it for Zettelkasten, although it's not our main value proposition.

Why: Saga automatically links pages one to another, so it builds your wiki/knowledge system automatically for you.

You can also group pages in "Collections", which are smart tags similar to the Zettelkasten tagging method, which allows users to easily recollect and find notes.

I welcome anybody to try Saga for Zettelkasten and give us feedback on how we can make it a better tool for this use case!
