DebugProbe.AspNetCore: A Minimalist Tool for API Debugging

My project is starting to get solid.

I really like how it’s starting to look. Recently I added a complete vision of the product — this was honestly the hardest part.

I’m trying to keep everything minimalistic. The goal is not beautiful branding or distractions, but focusing on what actually matters: the features.

As I mentioned, here are the features:

• Capture HTTP requests & responses
• Inspect headers, query, and body
• JSON pretty formatting
• Side-by-side response comparison
• Built-in UI (/debug)
• Zero configuration

The target is:

• Debug real requests directly inside your app
• No proxy setup or traffic interception
• See exactly what your API sends and receives
• Compare environments in seconds

Screenshots:

Compare

Compare across environments easily by entering:

• Base URL
• Trace ID

…and instantly see the differences.

In the next post, I’ll show how simple the setup is — it takes less than 2 minutes.
