Instagram doesn't have any easy way that I could find to track your number of followers and people you're following over time so I made this web-srcaping script. A python script that tracks an account's followers, following, and post counts. Ideally this is running on a regular schedule for provide even data points. Paste a url into the URL.txt file to check that account.
The current URL.txt file and pastData.json file are examples with my own Insta account.
