I've recently moved to kubuntu. Is there any app to read HTTP Archive Log (.har). I know about this http://www.softwareishard.com/har/viewer/. I'm looking for an offline app to view .har files.

Thanks, jeetesh


You can use HAR Viewer

HAR Viewer is a web application (PHP) that allows to visualize HTTP tracing logs based on HTTP Archive format (HAR). These files contain recorded information about HTTP traffic performed by web pages. A HAR log can be created by HTTP sniffer tools such as Firebug.

It's still web-based, somehow, but you can use it on a local server

  • That's the same viewer that's mentioned in the question. – Tgr Nov 24 '17 at 21:05

Of all the offline tools that work on Ubuntu, the HTTP Archive Viewer Chrome extension is probably the easier to install (the other alternatives are web apps that you can host locally, and command line tools which don't give you a useful overview). It's nothing fancy, but it can display a timeline similar to the one in Chrome Developer Toolbar's Network tab, and can show the headers and body of each request and response.


HAR files appear to be JSON files, so for basic analysis you can parse the JSON manually.


there are a number of tools / apps that can help visualize .har files and data:

  • HTTP Archive Reader and HTTP Watch are Windows-only (and the latter costs something ridiculous). harview just lists the requests - it's not a "viewer" in the sense that the softwareishard one is. ChromeHAR is not an offline viewer (you can host it locally, but then you can do that with the softwareishard viewer aswell). – Tgr Nov 24 '17 at 21:04
