The short version
- Only Nginx 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.; Nginx open-source nginx has no admin API for changing arbitrary config at runtime; dynamic reconfiguration requires editing the config file and reloading via 'nginx -s reload'
- They diverge on capability: Cortex covers Service catalogue, Nginx covers High-performance web server.
- Prices and features above were last checked on 31 August 2026.
Where they differ

What people use each for
The jobs each tool is most often brought in to do.
Cortex

- An organisation where ownership of production services is genuinely unknown after reorganisations or acquisitionsnot Nginx
- Enforcing production readiness standards on new services at creation time rather than at incident reviewnot Nginx
- Replacing a self-hosted Backstage that is consuming a full-time engineer or two just to stay upgradednot Nginx

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.
Nginx
- Open-source nginx has no admin API for changing arbitrary config at runtime; dynamic reconfiguration requires editing the config file and reloading via 'nginx -s reload'
- No official built-in GUI or dashboard for management or live metrics in the open-source edition
- Advanced capabilities such as active health checks, dynamic upstream reconfiguration without reload, and a full API gateway feature set are exclusive to the paid NGINX Plus product, not open-source nginx
- No published list price for NGINX Plus on the current F5 product page; pricing requires contacting sales

Questions people ask
- Is Cortex or Nginx better?
- Neither clearly leads. Cortex starts at On request and Nginx at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Cortex or Nginx?
- Nginx has a free tier; the other does not. Paid plans start at On request for Cortex and Free for Nginx.
- Does Cortex or Nginx run on more platforms?
- Cortex runs on Web, API. Nginx runs on Windows, macOS, Linux.
- Can I use Nginx for free?
- Yes. Nginx has a free tier, so you can try it without paying. Cortex starts at On request.
- What is Cortex best used for?
- Cortex is most often used for a platform team that needs to prove to leadership how far a kubernetes or framework migration has actually progressed across hundreds of services, an organisation where ownership of production services is genuinely unknown after reorganisations or acquisitions, enforcing production readiness standards on new services at creation time rather than at incident review, replacing a self-hosted backstage that is consuming a full-time engineer or two just to stay upgraded. Of those, a platform team that needs to prove to leadership how far a kubernetes or framework migration has actually progressed across hundreds of services and an organisation where ownership of production services is genuinely unknown after reorganisations or acquisitions are not what Nginx is typically brought in for.
- What can Cortex do that Nginx cannot?
- Cortex covers Service catalogue, Scorecards, Initiatives, Self-service templates. Nginx covers High-performance web server, Reverse proxy, Load balancing, HTTP caching.
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.
Nginx: How much does nginx cost?
nginx is free and open source software distributed under the 2-clause BSD License. Enterprise distributions, commercial support, and training are available from F5 Inc. at custom pricing.
SourceCortex: Is pricing published?
No. Cortex requires a sales conversation and prepares a custom proposal.
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.
