How do I view / replay a chrome network debugger har file saved with content?

I love the network debugger, that being said, what programs are out there that let me step forward and backward through multiple 'hars' so I can replay them? if the 'hars' are saved with content, can the replay handle that as well?

right now I just read through in textpad, but if I have to present any of my findings a nice 'har player' could greatly help non-technical folk.

Solution 1:

There is an HAR Viewer developed by Jan Odvarko that you can use. You either use the online version at

• http://www.softwareishard.com/har/viewer/ (older version)
• http://gitgrimbo.github.io/harviewer/master/ (up-to-date master branch)

Or download the source-code at https://github.com/janodvarko/harviewer.

EDIT: Chrome 62 DevTools include HAR import functionality. https://developers.google.com/web/updates/2017/08/devtools-release-notes#har-imports

Solution 2:

Chrome Dev Tool's "Network" tool now allows you to import HAR files by drag-and-dropping into the window.

Solution 3:

There are a couple of online, offline tools how to do this:

• HAR viewer
• HAR analyser

But the one that I liked the most, is a browser extension (tried it in chrome, hopefully it works in other browsers). After installation, it appears in your apps as HAR viewer. Then you can upload you HAR file and see something like this:
