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

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
