@scalequality/backstage-plugin

Render ScaleQuality's measured quality signals as an entity card in Backstage: AI durability, engineering maturity, code maturity and your tech radar, for the org, business unit or team the entity maps to. One click deep-links back into ScaleQuality for the full story.

The card reads ScaleQuality's public read-only /v1 API through the Backstage backend proxy, so your org-scoped API key (sq_live_...) is injected server-side and never reaches the browser.

The card

The entity card renders theme-aware from real measured signals, so it stays clean in both Backstage themes.

Install

# from your Backstage app root
yarn --cwd packages/app add @scalequality/backstage-plugin

1. Configure the proxy

Add to app-config.yaml (the key stays in your backend / secret store):

proxy:
  endpoints:
    '/scalequality':
      target: https://app.scalequality.io/v1
      changeOrigin: true
      headers:
        Authorization: 'Bearer ${SCALEQUALITY_API_KEY}'

Create the API key in ScaleQuality under Developers, then set SCALEQUALITY_API_KEY in your environment. The key is read-only and scoped to your org.

2. Add the card to your EntityPage

packages/app/src/components/catalog/EntityPage.tsx:

import { EntityScaleQualityCard } from '@scalequality/backstage-plugin';

// inside the entity page grid, e.g. the overview content:
<Grid item md={6}>
  <EntityScaleQualityCard />
</Grid>

3. Map entities to a ScaleQuality scope

Annotate the entity (Component / Group) with the ScaleQuality id it should show. Most specific wins (team > BU > org):

metadata:
  annotations:
    scalequality.io/team-id: <team-uuid>
    # or: scalequality.io/bu-id: <bu-uuid>
    # or: scalequality.io/org-id: <org-uuid>

Find the ids in ScaleQuality's GET /v1/catalog, or in the deep-link URLs.

What it shows

Signal	Source	Provenance
AI durability (survival % + rework $)	git-attributed telemetry	MEASURED
Engineering maturity (L1–L5)	assessment scorecards	MEASURED
Code maturity (score /100 + sub-scores)	zero-config Diagnosis	MEASURED
Tech radar (ring counts)	configured tech landscape	DECLARED

A signal with no measurement yet renders as —, never a fake value.
