  • Each has a real cost: RAD Studio professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax; Radix UI you write all the styling, so time to a finished interface is much longer than with a styled library

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

RAD Studio

  • Professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax
  • Enterprise edition steps up to $3,400 license plus $1,199 maintenance, and Architect edition to $4,416 license plus $2,183 maintenance
  • The perpetual license only entitles the buyer to updates for one year; continued access to new updates and upgrades requires an annually renewable Update Subscription

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
