Platform engineering toolkit for service catalogs

1. Port

(Best for speed)

A managed catalog with integrations, custom service models, scorecards, and self-service actions. A strong choice when you want a working portal without maintaining its underlying framework.

Trade-off: recurring licensing costs and less freedom than a fully custom portal.

2. Backstage

(Best open source)

A flexible, CNCF-incubating developer portal framework with a software catalog, documentation, plugins, and scaffolding templates.

Trade-off: you own hosting, upgrades, integrations, and ongoing engineering work.

3. Cortex

Best if the catalog needs to drive engineering standards: service ownership, production readiness, reliability, and maturity scorecards.

Trade-off: commercial procurement and configuration may be more than you need for a basic directory.

4. OpsLevel

A managed option to investigate if automated service discovery, ownership mapping, and service maturity tracking matter more than building a custom portal.

Trade-off: quote-based pricing and a more governance-oriented use case.

A practical toolkit to get started in a day

For a quick proof of concept, keep the stack small:

Port or Backstage

Service catalog and developer interface

GitHub or GitLab

Repositories, metadata, ownership files

Catalog entities

Services, teams, dependencies, docs, lifecycle

Add observability later

Links to Grafana, Datadog, PagerDuty, and CI/CD

Suggested first-day implementation

1. Connect your Git provider and import a small set of representative services.
2. Define a minimal schema: service name, owning team, repository, lifecycle, criticality, documentation, and dependencies.
3. Validate ownership and metadata against the source repositories.
4. Add links to dashboards, runbooks, and deployment pipelines.
5. Ask a few developers to find a service and identify its owner without help.

Don't start by integrating every tool or implementing a complex scorecard. First establish that the catalog is accurate and useful.

Which should you choose?

• Need a working catalog with minimal platform-team effort? Port.
• Need open source, extensibility, and control over deployment? Backstage.
• Need ownership accountability and maturity scorecards? Cortex or OpsLevel.

One question would help me narrow this down: Are you looking for a quick catalog for an existing fleet of services, or a full internal developer portal with self-service provisioning too?
