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

Question

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

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

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:

The Most Reliable way to replay har file is using a free tool like Fiddler, the tool is always free and can be downloaded quickly. The sites for the opening har file are all buggy and cannot open large files. Fiddler is available for all platforms.

Go to File Menu -> Import Sessions...

Select the "HTTPArchive" Option

Browse to your HAR file

The HAR file will open and replay on the fiddler window.
