Build an AI-Powered Developer Portal with Backstage and .NET

Want to apply AI, not just read about it? Most tutorials stop at a "Hello World" chatbot. We are going to build something that actually solves a common engineering headache: stale documentation.

Who this is for

This guide is for platform engineers and .NET developers who need to organize a growing software landscape without forcing teams to manually write YAML files.

What you will build

You will build a dynamic developer portal using Backstage that automatically populates its service catalog. We will use a .NET CLI tool to scan source code and use local AI ( Ollama ) to generate summaries.

Source repo: demo-backstage-catalog-generator

Constraint: We use local inference only. No source code ever leaves your machine.

Have you ever needed to update a service, but forgot what it does? Or spent time trying to understand code you have not touched in months?…
