The short version

  • Only Spring Boot has a free tier, so it costs nothing to try first.
  • 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.; Spring Boot requires Java 17 as the minimum version for Spring Boot 4.1.0, per docs.spring.io/spring-boot/system-requirements.html (Aug 2026); older Java runtimes are not supported
  • Prices and features above were last checked on 31 August 2026.

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.

Spring Boot

  • Requires Java 17 as the minimum version for Spring Boot 4.1.0, per docs.spring.io/spring-boot/system-requirements.html (Aug 2026); older Java runtimes are not supported
  • Requires Spring Framework 7.0.8 or above and Gradle 8.14+ or Maven 3.6.3+, per Spring's own system requirements page, so older toolchains must be upgraded first

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.

Spring Boot: Is Spring Boot free?

Yes, Spring Boot is free and open-source software. The core framework is available without cost, and users can download and use it immediately.

Source
Cortex: Is pricing published?

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

Spring Boot: What commercial support is available for Spring Boot?

While Spring Boot itself is free, VMware offers optional commercial support, training, and certification through Spring Academy. Tanzu Spring provides support and binaries for OpenJDK, Spring, and Apache Tomcat through a subscription model for enterprises requiring guaranteed support.

Source
Cortex: Can it self-host?

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

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.
