What should I use for service ownership and dependency mapping?

For service ownership and dependency mapping, the best choice depends on whether you want a simple system of record or a full service catalog / architecture platform.

Good options

1. Backstage

Best if you want an internal developer portal with:

• service ownership
• API/service catalog
• dependency relationships
• documentation
• scorecards and templates

Why use it:
It’s one of the most popular open-source options for mapping services and assigning owners. It works well if you want a centralized, developer-friendly catalog.

Good for: mid-size to large engineering orgs, platform teams, DevEx teams.

2. ServiceNow CMDB

Best if you need:

• formal asset/service ownership
• enterprise governance
• change management
• audit/compliance integration
• dependencies across infrastructure and applications

Why use it:
Very strong for enterprise IT and operations, especially when you need process-heavy governance.

Good for: large enterprises, ITSM-heavy environments.

---

3. Atlassian Compass

Best if you use Atlassian tools and want:

• service catalog
• ownership metadata
• dependency views
• engineering health signals

Why use it:
Fairly easy to adopt and integrates nicely with Jira/Confluence.

Good for: teams already in the Atlassian ecosystem.

4. LeanIX / Bizzdesign / Ardoq

Best if you want enterprise architecture tooling with:

• application/service portfolio
• dependency mapping
• capability mapping
• roadmaps and governance

Why use it:
Strong for architecture and business alignment, less developer-centric than Backstage.

Good for: enterprise architecture and transformation programs.

5. Simple starting point: spreadsheets + diagrams

If you're early stage, you can start with:

• a spreadsheet for ownership
• diagrams in Miro/Lucidchart/draw.io
• a shared doc for service definitions

Why use it:
Fast and cheap, but it doesn’t scale well and gets stale quickly.

Practical recommendation

If your goal is service ownership + dependency mapping for engineering teams, I’d usually recommend:

• Backstage if you want a modern, extensible developer portal
• ServiceNow if governance/ITSM is the priority
• Compass if you want something lighter and already use Atlassian
• LeanIX/Ardoq if you need enterprise architecture views

What to look for

Whatever tool you choose, make sure it supports:

• clear owner assignment
• team ownership, not just individual names
• service metadata
• upstream/downstream dependency links
• automated sync from source systems where possible
• API support or integrations with Git/Jira/Kubernetes/cloud

My short answer

If you’re asking for the best all-around choice for engineering service ownership and dependency mapping, start with Backstage.

If you want, I can also give you:

1. a decision matrix comparing these tools, or
2. a recommended data model for service ownership and dependencies.
