Choosing well
Match the deployment model
Check whether you need a web or API service, a self-hosted installation, or a desktop platform. The listed deployment options include web, API, self-hosted, Linux, macOS and Windows.
If developers will work away from a desk, confirm whether the web interface works well on a phone and whether an Android app is available.
Compare free and paid plans
A free plan is available from items in this category, and a free trial is offered by items on the list. Check what the free tier includes before moving a catalog or templates into production.
Paid pricing varies: Atlassian Compass lists $7.67 per user per month, configure8 lists $19 per user per month on annual billing, and Cycloid lists $29 per user per month on annual billing. Other tools show pricing on request or higher monthly starting prices.
Check catalogs and templates
A service catalog can give developers a shared view of software components. Software templates help standardize how new services or projects are created.
Compare how the catalog and templates fit your existing workflow, deployment model and API needs.
Review engineering controls
Engineering scorecards can help track standards, while role-based access controls who can view or change platform information. Audit logs provide a record of platform activity.
Check which of these controls are included in the plan you would use, rather than assuming they come with a free tier.
Confirm Kubernetes support
Kubernetes support matters if your platform workflows run on Kubernetes. Compare how that support fits with your chosen deployment model and service catalog.
Koryx describes itself as an open-source GitOps control plane for building internal developer platforms on Kubernetes; Backstage and Gantry are listed as free or open-source options.
