Backstage is an open source framework for building developer portals, created by Spotify and now hosted by the Cloud Native Computing Foundation as an Incubation level project. The framework is built around a centralized software catalog that brings order to microservices and infrastructure environments, enabling product teams to ship code quickly while maintaining autonomy. Written primarily in TypeScript, Backstage unifies infrastructure tooling, services, and documentation into a streamlined development environment.
The core features included out of the box are the Backstage Software Catalog for managing microservices, libraries, data pipelines, websites, and ML models; Backstage Software Templates for spinning up new projects and standardizing tooling with organizational best practices; and Backstage TechDocs, which implements a docs-like-code approach to making technical documentation easier to create, maintain, find, and use. The framework also includes a growing ecosystem of open source plugins that expand customizability and functionality for specific organizational needs.
The repository demonstrates significant community engagement and active maintenance.
The repository's scope spans multiple interconnected domains including service discovery, internal tooling, documentation management, catalog management, plugin architecture, and DevOps tools. This breadth is reflected in GitGenius classifications that identify Backstage as relevant to service catalogs, monorepo management, infrastructure visibility, deployment pipelines, and lifecycle management.
Backstage's community engagement extends beyond code contributions through multiple channels including a Discord chatroom, monthly community sessions, RFC processes for technical direction, and an adopters list documenting companies already using the framework. The project maintains comprehensive documentation covering main documentation, software catalog features, architecture decisions, design systems, and UI component storybooks. The framework's positioning as a CNCF Incubation project reflects its maturity and importance within the cloud native ecosystem, particularly for organizations managing complex microservices architectures and seeking to improve developer experience through centralized infrastructure visibility and self-service capabilities.
