I Built a VS Code Style Playground to Visualize Real .NET Backend Architecture

Question

Most backend developers learn Clean Architecture and DDD from diagrams or GitHub repos.

But there is a problem.

You rarely see how a real production backend is structured in a way that feels interactive and intuitive.

So I decided to build something simple to fix that.

The idea

A lightweight web tool that lets you explore a real .NET backend like you would explore a project in VS Code.

No cloning repositories.
No setup.
No debugging environment.

Just open and browse.

---

What it shows

The tool simulates a real production .NET Clean Architecture project with:

• Domain layer (Entities, Value Objects)
• Application layer (Services, DTOs)
• Infrastructure layer (Repositories, Persistence)
• API layer (Controllers, Middleware)

You can click through folders and files just like a real codebase.

Why I built it

I kept noticing a gap:

Beginners and even intermediate developers understand concepts like DDD, but struggle to visually connect how everything fits together in a real project.

Reading code is one thing.
Navigating a structured system is another.

I wanted something that bridges that gap.

---

What it is not

This is not an IDE.
It is not a full development environment.
It is not meant for editing code.

It is a visual exploration tool for backend architecture.

What’s next

This is the first version.

Next steps might include:

• multiple backend templates (SaaS, auth system, etc.)
• deeper explanations per file
• guided architecture walkthroughs

But for now, the goal is simple:

Make backend structure easier to understand by seeing it.
