Silverbullet is aptly named but I'd actually wait a month or two because it's going through the transition to V2 which shuffles a few things around.

Other than that it's exactly what it says on the tin, a hacker's digital notebook. While it would take a bit of rolling up your sleeves to make it look as nice as Logseq or Obsidian it's actually closer in form and function to something like org-mode for Emacs (though not quite hitting the mark regarding linking sadly).
