+title: Capturing web traffic with Chrome's NetLog dumper
+---
+When trying to debug things in the browser, it's common to pop open your browser's dev tools or reach for an OS level proxy such as [Proxyman](https://proxyman.io/).
+
+One alternative for Chromium browsers that surfaces useful information is [chrome://net-export](chrome://net-export). That URL should resolve both in Google Chrome as well as Chromium-based browsers such as Brave, Edge and so on.
+
+You'll be presented with a pretty plain looking page.

+
+You can basically pick whether you want to strip private info and what the maximum log size should be.
+
+Clicking "Start Logging to Disk" will start spooling data to a JSON file until you stop doing so.
+
+So, once you've got a NetLog dump, now what?
+
+You can use the browser-based [Netlog Viewer](https://netlog-viewer.appspot.com/#import) which will render the contents within your browser rather than sending them off to a third party.

+
+This can be useful if you want to share your net dump with a coworker who may be helping to debug a technical issue for example.
+
+There's a lot of useful insights in here such as a full timeline of traffic, including disc cachingwhich wouldn't be captured by a standard man in the middle proxy.

+
+There are also a lot of other standard things like DNS lookups which can be valuable for debugging.

+
+You can even see what extensions were loaded at the time, which may help to figure out if any of them may have been modifying traffic in a way that causes problems.
