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

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.
