Decoupling service maturity: Scaling Backstage Tech Insights with a push-based architecture

As organizations scale, tracking service maturity is critical to maintaining security, reliability, and standards. Backstage Tech Insights offers a shared foundation for this, but its default pull-based model requires fact retrievers to live inside the Backstage codebase. In large environments, this leads to a growing collection of retrievers and third-party dependencies, increasing vulnerability scanning noise, forcing teams into a TypeScript-only workflow, and complicating dependency management. These factors make Backstage upgrades riskier and more costly to coordinate.

In this session, the presenters introduce a generic Fact Retriever Factory and a shift to a decoupled, push-based architecture. Teams can build fact retrievers in the language of their choice, in their own repositories, and push data to a central endpoint. Attendees will learn how to lower maintenance overhead, simplify Backstage upgrades, and enable broader contributions to service maturity without repository bottlenecks.
