Internal developer portal that scores service ownership and maturity rather than just cataloguing services

The short version
- Only Argo CD has a free tier, so it costs nothing to try first.
- Each has a real cost: Argo CD licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare; 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.

Where they differ
Only the attributes on which Argo CD and Cortex actually diverge.
Identical on both: user rating (Not yet rated), category (Developer Tools).

What people use each for
The jobs each tool is most often brought in to do.
Argo CD
- Declarative GitOps continuous deployment for Kubernetes applicationsnot Cortex
- Automated configuration drift detection across multiple clustersnot Cortex
- Multi-environment management with blue/green and canary deploymentsnot Cortex
- Enterprise authentication with SSO, OIDC, OAuth2, LDAP, SAML 2.0not Cortex
- Webhook integration for GitHub, BitBucket, and GitLab automationnot Cortex
Cortex
- A platform team that needs to prove to leadership how far a Kubernetes or framework migration has actually progressed across hundreds of servicesnot Argo CD
- An organisation where ownership of production services is genuinely unknown after reorganisations or acquisitionsnot Argo CD
- Enforcing production readiness standards on new services at creation time rather than at incident reviewnot Argo CD
- Replacing a self-hosted Backstage that is consuming a full-time engineer or two just to stay upgradednot Argo CD
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Argo CD
- Licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare
- The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly
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.

Questions people ask
- Is Argo CD or Cortex better?
- Neither clearly leads. Argo CD starts at Free and Cortex at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Argo CD or Cortex?
- Argo CD has a free tier; the other does not. Paid plans start at Free for Argo CD and On request for Cortex.
- Does Argo CD or Cortex run on more platforms?
- Argo CD runs on Web. Cortex runs on Web, API.
- Can I use Argo CD for free?
- Yes. Argo CD has a free tier, so you can try it without paying. Cortex starts at On request.
- What is Argo CD best used for?
- Argo CD is most often used for declarative gitops continuous deployment for kubernetes applications, automated configuration drift detection across multiple clusters, multi-environment management with blue/green and canary deployments, enterprise authentication with sso, oidc, oauth2, ldap, saml 2.0. Of those, declarative gitops continuous deployment for kubernetes applications and automated configuration drift detection across multiple clusters are not what Cortex is typically brought in for.
- What can Argo CD do that Cortex cannot?
- Cortex covers Service catalogue, Scorecards, Initiatives, Self-service templates.
Answered from the vendors’ own pages
Argo CD: What is the cost of Argo CD?
Argo CD is open source and free to use. No licensing fees, subscription charges, or commercial restrictions apply. The project is maintained by the CNCF community.
SourceCortex: 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.
Argo CD: How frequently does Argo CD poll Git repositories by default?
Argo CD checks Git and Helm repositories every 3 minutes by default to detect configuration changes, enabling timely deployment of updates.
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.
