Where each one falls short

Notepad++

  • Windows-only, with no official native macOS or Linux build.
  • Lacks built-in debugging or project/build management found in full IDEs.
  • Plugin quality and maintenance varies since they are community-contributed.
  • No built-in version control integration beyond what plugins provide.

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
