Explain

httpstat is a python script, which reflects curl statistical analysis in a wonderful and proper way. It is a single script, compatible with Python 3, and does not need to install additional software (dependency) on the user's system.
In essence, it is an encapsulation of cURL tool, which means you can use several valid cURL options after the URL, but excluding - w, - D, - o, - s and - s options, which have been used by httpstat.

Installation:

wget -c https://raw.githubusercontent.com/reorx/httpstat/master/httpstat.py
or
pip install httpstat
