httpmon exports captured traffic as HAR 1.2 files. You can open these in browser DevTools, Google’s HAR Analyzer, or any tool that reads the HAR format.

​
Export all flows

Press x in the list view to export every captured flow at once.

​
Export a single flow

Press x in the detail view to export only the selected flow.

​
File naming

A modal prompts you for a filename. The default is httpmon-{timestamp}.har, where {timestamp} is the current date and time.

​
Exported fields

Each HAR entry includes:
  • Request — method, URL, headers, and body
  • Response — status code, headers, and body
  • Timings — connection, wait, and transfer durations

​
Viewing HAR files

Open the exported .har file in:
  • Chrome or Firefox DevTools (Network tab, import)
  • Google HAR Analyzer
  • Any HAR-compatible viewer
