The Github repo was helpful:

- Phase 1: Extensible frontend platform (now) - You will be able to easily create a single consistent UI layer for your internal infrastructure and tools. A set of reusable UX patterns and components help ensure a consistent experience between tools.

- Phase 2: Manage your stuff (next 2-3 months) - Manage anything from microservices to software components to infrastructure and your service catalog. Regardless of whether you want to create a new library, view service deployment status in Kubernetes, or check the test coverage for a website -- Backstage will provide all of those tools - and many more - in a single developer portal.

- Phase 3: Ecosystem (later) - Everyone's infrastructure stack is different. By fostering a vibrant community of contributors we hope to provide an ecosystem of Open Source plugins/integrations that allows you to pick the tools that match your stack.

It looks like an onboarding tool, monitoring, and knowledge database.
