Backstage

Backstage is an open-source framework for building developer portals that unifies all your infrastructure tooling, services, and documentation into a centralized software catalog, helping teams manage microservices and ship code quickly while maintaining standards across the organization.

Delivering internal developer portals.

Backstage is an open-source platform (created at Spotify and now a CNCF project) for building internal developer portals that centralize a company’s software ecosystem—services, data pipelines, websites, libraries, infrastructure, and more—into a single, searchable catalog. It provides opinionated building blocks like the Software Catalog, Software Templates (scaffolder) for “golden paths,” TechDocs for docs-as-code, and a rich plugin system so teams can surface CI/CD status, deployments, cost, ownership, and runbooks in one place. The goal is to tame sprawl, standardize workflows, and give developers a self-service hub that speeds delivery while improving reliability and governance.
