Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

Radix UI

  • You write all the styling, so time to a finished interface is much longer than with a styled library
  • Composable part-based APIs are more verbose than a single component with props
  • Covers primitives rather than complex widgets, so data grids and date pickers come from elsewhere
