The short version

  • Only Nx Cloud 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.; Nx Cloud requires Nx workspace setup; integration limited to Nx build system
  • They diverge on capability: Cortex covers Service catalogue, Nx Cloud covers Nx Replay.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Cortex

  • A platform team that needs to prove to leadership how far a Kubernetes or framework migration has actually progressed across hundreds of servicesnot Nx Cloud
  • An organisation where ownership of production services is genuinely unknown after reorganisations or acquisitionsnot Nx Cloud
  • Enforcing production readiness standards on new services at creation time rather than at incident reviewnot Nx Cloud
  • Replacing a self-hosted Backstage that is consuming a full-time engineer or two just to stay upgradednot Nx Cloud

Nx Cloud

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.

Nx Cloud

  • Requires Nx workspace setup; integration limited to Nx build system
  • Free tier restricted to 5 contributors; larger teams require paid plans
  • Credits system adds complexity to cost prediction vs flat-rate competitors
  • Self-hosted Enterprise deployment requires significant operational overhead

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.

Nx Cloud: What is included in the free Hobby plan?

The Hobby plan includes 50,000 monthly credits, support for 5 contributors, 10 concurrent CI connections, and basic analytics at no cost with no credit card required.

Source
Cortex: Is pricing published?

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

Nx Cloud: How are overages charged on the Team plan?

The Team plan starts at $29/month with included credits. Additional credits cost $5.50 per 10,000 credits, extra contributors cost $19 each, and additional CI connections cost $2.25 each.

Source
Cortex: Can it self-host?

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

Nx Cloud: Can Nx Cloud be self-hosted?

Yes, Enterprise customers can deploy Nx Cloud on-premises or on managed infrastructure to maintain full control over data and infrastructure.

Source
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.
