Backstage

Purpose: Backstage is an open-source framework for creating and deploying developer portals, originally created at Spotify.
Software catalog: The catalog tracks software ownership and metadata, including services, websites, libraries, and data pipelines.
Catalog scale: Backstage says its catalog can help a team manage 10 services and make it possible for a company to manage thousands.
Templates: Software Templates can load code skeletons, substitute variables, and publish generated projects to locations such as GitHub or GitLab.
TechDocs: TechDocs uses a docs-like-code approach that keeps documentation close to the code.
Integrations: Integrations let Backstage read or publish data using providers such as GitHub, GitLab, Bitbucket, LDAP, and cloud providers.
Plugin ecosystem: A Backstage portal can be customized with existing open-source plugins or plugins built by the adopter.
Deployment: The standalone installation guide creates a locally running app with an in-memory SQLite database and demo content, and says this setup is not production-ready.
Requirements: The standalone app guide lists minimum requirements of 20 GB disk space and 6 GB memory, with additional disk space needed as modules and plugins are added.
Security: Backstage's threat model recommends enabling only the authentication providers an instance uses and configuring sign-in resolvers carefully.
Security limit: The threat model says Backstage provides only rudimentary protection against denial-of-service attacks and is primarily designed for deployment in a protected environment.
Support: The project documentation links to a community support chatroom and contribution resources.
Product: Backstage is an open-source framework for building developer portals.
Search: Backstage Search is an extensible platform that can index sources such as TechDocs, Confluence, and Stack Overflow.
