I needed to capture network logs from a colleague's browser without asking them to open DevTools — so I built this. Here's how it works..

Network Logger - HAR Exporter (Chrome Extension)

Capture network requests across all tabs and export as a HAR file — no DevTools needed. Perfect for debugging and sharing logs.

Key difference from DevTools: DevTools must be open and on the correct tab before the request fires. Network Logger captures traffic from all tabs the moment you click Start, even if DevTools has never been opened

Below is quick overview of chrome extension
