Where each one falls short

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

NestJS

  • Licensed under the MIT License per nestjs.com; the core framework has no paid tier, but the Enterprise support offering (architectural reviews, LTS, upgrade assistance) is sold by direct contact with no published rate
  • Built specifically on TypeScript and Node.js, per nestjs.com's own description, so it requires that runtime and cannot be adopted independently of the Node.js ecosystem

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
