httpstat A Curl Statistics Tool to Check Website Performance

httpstat is a Python script that reflects curl statistics in a fascinating and well-defined way, it is a single file which is compatible with Python 3 and requires no additional software (dependencies) to be installed on a users system.

It is fundamentally a wrapper of cURL tool, means that you can use several valid cURL options after a URL(s), excluding the options -w, -D, -o, -s, and -S, which are already employed by httpstat.

note that body length is limited to 1023 bytes, will be

To use them, simply export the variables with the appropriate value in the .bashrc or .zshrc file.

For instance:

export  HTTPSTAT_SHOW_IP=false
export  HTTPSTAT_SHOW_SPEED=true
export  HTTPSTAT_SAVE_BODY=false
export  HTTPSTAT_DEBUG=true

Once your are done adding them, save the file and run the command below to effect the changes:

$ source  ~/.bashrc

You can as well specify the cURL binary path to use, the default is curl from current shell $PATH environmental variable.

Below are a few examples showing how httpsat works.

$ python httpstat.py google.com
