The short version

  • Each has a real cost: Cortex pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.; RAD Studio professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax

Where each one falls short

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

Cortex

  • Pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.
  • The catalogue is only as accurate as the metadata you supply, so an organisation with inconsistent repository conventions spends its first quarter cleaning data before any scorecard means anything.
  • Scorecards create political friction: publishing a per-team grade turns an engineering standard into a performance metric, and teams will game the rules rather than fix the underlying issue.
  • It is closed source and hosted, so organisations with strict data residency or air-gap requirements have limited options compared with running Backstage themselves.
  • Value scales with organisation size, so a company with fifty engineers and thirty services will find the catalogue tells them nothing they did not already know while still paying an enterprise contract.

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

Answered from the vendors’ own pages

Cortex: How is Cortex different from Backstage?

Backstage is an open source framework you build and staff. Cortex is a hosted product with scorecards and initiatives out of the box and no platform team required to keep it running.

RAD Studio: How much does RAD Studio cost?

RAD Studio uses perpetual licensing: Professional Edition $2,000 perpetual license + $599 first year maintenance ($2,599 total + tax). Enterprise Edition $3,400 license + $1,199 maintenance ($4,599 total + tax). Architect Edition $4,416 license + $2,183 maintenance ($6,599 total + tax).

Cortex: Is pricing published?

No. Cortex requires a sales conversation and prepares a custom proposal.

RAD Studio: What is the difference between RAD Studio editions?

Professional Edition ($2,599 total + tax) targets individual developers. Enterprise Edition ($4,599 total + tax) adds multi-tier app capabilities. Architect Edition ($6,599 total + tax) includes advanced database and cloud features. All three include perpetual licenses.

Cortex: Can it self-host?

It is offered as a hosted product; on-premise arrangements are handled through sales rather than published.

RAD Studio: Does RAD Studio offer Kai AI integration and discounts?

Yes, adding Kai AI to any edition provides discounts: 25% off Professional ($2,136 + tax), 30% off Enterprise ($3,394 + tax), and 40% off Architect ($4,109 + tax). This promotion is active through August 31, 2026.

Cortex: What is the main adoption risk?

Bad or missing service metadata. The catalogue and every scorecard on top of it inherit whatever quality your repositories already have.
