## What it is
Backstage is an open-source framework, originally created by Spotify and now a CNCF Incubation project, for building internal developer portals. It provides a centralized software catalog, scaffolding templates, docs-like-code TechDocs, and a large plugin ecosystem to unify infrastructure tooling and services.

## Use cases
- build an internal developer portal for my engineering org
- create a centralized catalog of all microservices and infrastructure
- standardize how new projects are scaffolded with templates
- make technical documentation easy to find and maintain
- give product teams self-service access to infrastructure tooling
- track ownership and metadata of services, libraries, and ML models

## When to choose
- you have many microservices and need a single catalog of ownership and metadata
- you want to standardize project scaffolding and tooling across teams
- you need a self-service platform that unifies docs, CI/CD, and infrastructure tools
- you want an extensible portal backed by a large open-source plugin ecosystem

## When to avoid
- you are a small team with few services and simple tooling
- you cannot invest in hosting, customizing, and maintaining a portal
- you only need a static documentation site rather than a full developer platform

## Facets
