Quick Scoop

Backstage is an open source framework for building internal developer portals. It helps teams organize services, documentation, and developer tools in one place, and it was created at Spotify before being open sourced in 2020.

What it does

Backstage brings together a software catalog, templates for creating new projects, and TechDocs for technical documentation. It is meant to reduce tool sprawl and make it easier for developers to find what they need.

Why it matters

Companies use Backstage to centralize information about microservices, libraries, data pipelines, websites, and other software assets. The framework is widely adopted, with Spotify stating that more than 3,000 companies have used it for their own internal developer portals.

Latest context

Recent Backstage updates mention milestones like the New Frontend System, AI-native work, and ongoing community releases in 2026.

Simple example

A developer at a large company can use Backstage to look up who owns a service, read its docs, and start a new app from a standard template without digging through multiple internal systems.

If you want, I can also explain Backstage in:

  • plain English for beginners,
  • a technical view for engineers, or
  • a comparison with other developer portal tools.
