Internal Developer Platforms with GitHub: Backstage, Service Catalog, and the GitHub API

[steve-kaschimer]

Scheduled: 2026-11-20

Pitch: Backstage is the most widely adopted IDP framework, and GitHub is its most natural data source - this post shows how to wire them together so your catalog stays in sync with your actual codebase.

Angle: Covers deploying Backstage with the GitHub integration, writing catalog-info.yaml for a real service, auto-discovering catalog entries from GitHub repos using the GitHub Entity Provider, and using GitHub Actions to keep the catalog updated when repos are created or archived. Includes a GitHub App setup that gives Backstage read-only access without a PAT.
