This application checks the course roster every 20 minutes. Its speed is limited by updates to the course roster itself, which states:
"Class status (open/closed/waitlist) is refreshed every 10 minutes between 6am and 5pm, every 20 minutes between 5pm and midnight, and every hour between midnight and 6am (all times Eastern)."
I had to increase the time between intervals from 10 minutes to 20 minutes in order to stay within the AWS free tier (I make no revenue from this site so all payments to AWS would come out of my own pocket).

Developed by Justin Tran. Inspired by Course Sniper at Rutgers University.
