  • Requires self-hosting and technical setup; no managed hosting option in Classic version
  • Omeka S pricing not publicly disclosed, available only for download or sandbox testing
  • Limited scalability for institutions managing multiple extensive collections

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
