The short version

  • Each has a real cost: Logseq aGPL-3.0 licensing requires derivative works to be open-source; Sphinx reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
  • They diverge on capability: Logseq covers Markdown-based notes, Sphinx covers Cross-references.

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

Sphinx

  • reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
  • Configuration is complex and the default output is dated-looking without theme work
  • Build times on large documentation sets are slow
  • Heavier than the problem for a small project that only needs a few pages
