Where each one falls short

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

Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React
