The short version

  • Only shadcn/ui 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.; shadcn/ui no upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • They diverge on capability: Cortex covers Service catalogue, shadcn/ui covers Copy, not install.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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.

shadcn/ui

  • No upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • Requires Tailwind and React, so it is not an option outside that stack
  • Component code lives in your repository, which grows it and puts maintenance on your team
  • Its popularity has made the default look recognisable, which undercuts the customisation argument

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.

shadcn/ui: Is shadcn/ui free?

Yes, open source and free for commercial use.

Cortex: Is pricing published?

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

shadcn/ui: Why is it not an npm package?

So you own the code. Components are copied into your project, which makes customisation trivial — at the cost of receiving no automatic updates.

Cortex: Can it self-host?

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

shadcn/ui: Do I need Tailwind?

Yes. Components are styled with Tailwind utility classes and built on Radix primitives, so both are required.

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.
