Working remote or an online gamer; it is important to have reliable connection. When you check the download and upload speed, you may see no problems and Speedtest also shows the jitter. You can check a definition also here .
I was looking a good solution to see my network jiitter for a period of time. But that I couldn’t find any. So I developed my own jitter calculator and plotter tool.
Here is a screenshot below for the app. You can get the source code and use with python. Or you can use the MacOS or Windows binaries to check your network jitter.
Here is the github link where you can also download the binaries.
