Backstage

Backstage is an open-source framework for building internal developer portals. It provides a centralized, metadata-driven software catalog that tracks ownership, dependencies, and lifecycle status for all technical assets by harvesting configuration files directly from version control systems. The platform is built on a plugin-based modular architecture, allowing teams to extend core functionality through isolated, independently deployable modules that integrate into a unified frontend and backend ecosystem.

The project distinguishes itself through its focus on developer productivity and standardized workflows. It includes a template-driven scaffolding engine that automates the creation of new software projects, ensuring consistent architecture and best practices across teams. The platform also features granular, policy-based access control and secure proxy routing, which manage authentication and protect sensitive internal resources while aggregating infrastructure tools and documentation into a single, searchable interface.

Beyond its core catalog and scaffolding capabilities, the platform supports a wide range of operational needs, including infrastructure monitoring, technical documentation management, and automated notification delivery. It provides standardized patterns for custom plugin development, testing, and interface composition, enabling organizations to tailor the portal to their specific requirements. The system is designed to be extensible, with support for AI integration, usage analytics, and interface localization to accommodate diverse organizational needs.
