Backstage

Backstage is an open-source developer portal platform created by Spotify. It provides a centralized software catalog, software templates (scaffolder), TechDocs, and a plugin ecosystem for building customizable developer portals. Backstage helps organizations manage their software ecosystem by cataloging services, APIs, resources, and infrastructure, and provides tooling for creating new projects from templates.

Backstage publishes 15 APIs on the APIs.io network, including Events System, Actions API, Authentication API, and 12 more. Tagged areas include Developer Portal, Internal Developer Platform, Software Catalog, Open-Source, and Platform Engineering.

The Backstage catalog on APIs.io includes 2 event-driven AsyncAPI specifications, 1 JSON-LD context, and 3 Spectral governance rulesets.

Backstage’s developer surface includes sandbox, changelog, CLI, API reference, support, authentication, documentation, and 33 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/backstage: open an issue to ask a question, or submit a pull request to add artifacts.
