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

OBS Studio

  • The Windows build supports only Windows 10 and 11
  • The macOS build requires macOS 13.0 or newer
  • Linux support is distributed as a Flatpak and as a PPA for Ubuntu 24.04 and later rather than official packages for other distributions
  • Game Capture is a Windows only source

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
