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

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
