The short version
- Only PHP 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.; PHP distributed under the Modified BSD License, also called the PHP License version 4, per php.net/license/; there is no paid tier or vendor price to compare
- 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.
PHP
- Distributed under the Modified BSD License, also called the PHP License version 4, per php.net/license/; there is no paid tier or vendor price to compare
- PHP 8.2 lost active support on 31 Dec 2024 and enters full end of life on 31 Dec 2026, with only security fixes since, per php.net/supported-versions.php (Aug 2026)

- Does Cortex or PHP run on more platforms?
- Cortex runs on Web, API. PHP runs on Web.

- Yes. PHP 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 PHP is typically brought in for.
- What can Cortex do that PHP cannot?
- Cortex covers Service catalogue, Scorecards, Initiatives, Self-service templates.
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.
PHP: Is PHP free to use?
Yes, PHP is completely free and open-source software under the PHP Foundation governance. There are no licensing fees or paid tiers.
SourceCortex: Is pricing published?
No. Cortex requires a sales conversation and prepares a custom proposal.
PHP: Does the PHP Foundation offer paid support?
The PHP Foundation accepts voluntary donations to support long-term development, but donations are optional and not required to use PHP.
SourceCortex: 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.
