CDP API traffic capture: public launch

Starting with version 1.4.0, Progon intercepts network requests via Chrome DevTools Protocol (CDP) directly during scenario recording.

What’s new

• Every XHR and fetch made during recording is captured as a separate API step.
• Each step contains: method, URL, request body, headers, and the actual server response.
• During playback, Progon repeats the same request and compares the response against the expected value.

Why this matters

UI tests and API tests used to live in separate tools. Now a single Progon scenario covers both the user journey and the API layer — no need to set up Postman, pytest, or a separate framework.

How to get started

Enable the “Network interception” permission in the extension settings → start recording → perform actions in the browser → API steps will appear in the scenario automatically.
