Network Inspector

The NETWORK sub-tab in DEVTOOLS captures every HTTP request and response automatically. No configuration. No filter needed upfront. Everything goes in.

What Gets Captured

• Method — GET, POST, PUT, DELETE, PATCH
• Status code — 200, 304, 404, 500, etc.
• Content type — JSON, HTML, binary, etc.
• Response size — shown in bytes or KB
• Request headers — all headers sent with the request
• Response headers — all headers received back
• Request body — POST/PUT/PATCH body, decoded
• Response body — full server response, JSON auto-formatted
• Timestamp — hh:mm:ss.zzz

How to Use It

1. Open Nothing Browser
2. Go to the BROWSER tab and navigate to any site
3. Switch to DEVTOOLS → NETWORK
4. All requests are already there

Click any row to see the full detail in the right panel. Three sub-tabs:

Sub-tab	Content
Summary + Headers	Firefox-style view with decoded query params, full URL, all headers
Response	The server response body — JSON formatted if applicable
Raw	Raw HTTP/1.1 representation

Filtering

Use the filter bar to search by URL. The type dropdown filters by request type: XHR, Fetch, WS, Script, Doc, Img.

Export from Network Tab

Select any row and click:

• COPY HEADERS — copies summary + headers to clipboard
• COPY RESPONSE — copies response body to clipboard
• AS CURL — generates and copies a cURL command
• AS PYTHON — generates and copies a Python requests script
• DOWNLOAD — saves the full request + response to a .txt file

Cookies from the Cookie Inspector are automatically included in exports.

Capture Method

HTTP capture uses two layers:

1. QWebEngineUrlRequestInterceptor (Interceptor) — captures every request at the network layer, injects headers
2. JavaScript injection (NetworkCapture.captureScript()) — patches fetch and XMLHttpRequest to capture request bodies and response bodies

This dual approach is why request bodies (POST data) are captured correctly — the JS layer sees the body before it's sent.
