Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Logseq.

AGPL-3.0 licensing requires derivative works to be open-source
Mobile apps (iOS and Android) still in alpha/beta development stage
Self-hosted with local-first architecture, no built-in cloud sync option
No native synchronisation between desktop and mobile versions without setup
