Gartner defines internal developer portals as tools that enable self-service discovery, automation and access to reusable components, tools, platform services and knowledge assets in modern software development environments. The portals help improve developer experience and service reliability while enabling centralized governance and shared visibility across multiple teams. Capabilities include service and resource catalogs, scorecards to benchmark software quality and security, scaffolding templates for building new components and plug-ins for integrating with platform services. Platform engineering teams provide the portal to product development teams either as a stand-alone application or as integral components of DevOps platforms and broader internal developer platforms.
