  • They diverge on capability: Moonrepo covers Task orchestration, Sphinx covers Cross-references.

  • No commercial support option for organizations requiring guaranteed SLAs

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
