ContestBuzz - Your Personal Competitive Programming Notifier

With multiple contests happening across various platforms, staying updated and prepared can be a hassle for competitive programmers.

ContestBuzz is a smart contest tracking and notification platform that helps users stay informed about upcoming and ongoing coding contests across popular competitive programming websites — all in one place.

Contest Aggregation & Notification System

We used the Clist.by API to fetch real-time contest data from 5 major competitive programming platforms: CodeForces, CodeChef, LeetCode, AtCoder and GeeksforGeeks.

How it works:

• The Home Page displays all upcoming contests.
• On the Contests Page, users can:
• Filter contests by selected platforms
• View ongoing and upcoming contests
• Click the calendar icon to save contest date and time
• Click "Notify Me" to receive an email alert 1 hour before the contest starts
