FOLIO

  • FOLIO is open source with no vendor-run SaaS from the FOLIO project itself; adopters must self-host or contract a third-party hosting partner separately.

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
