⚠️ IMPORTANT NOTICE - GeeksforGeeks Integration (Updated: February 2026)GeeksforGeeks (GFG) support is currently unavailable due to the removal of their public API endpoint (
practiceapi.geeksforgeeks.org/api/vr/user-stats). This endpoint was deprecated by GeeksforGeeks in late 2024/early 2025 when they redesigned their platform.Current Status:
- ✅ LeetCode: Fully functional with GraphQL API
- ✅ CodeForces: Fully functional with REST API
- ❌ GeeksforGeeks: API returns 404 (Not Found) - endpoint permanently removed
What This Means:
- The application will display an error message for GFG profiles
- LeetCode and CodeForces analysis work perfectly
- All other features (duplicate detection, AI insights, charts) are fully operational
Future: GFG integration will be restored if/when they provide a new public API. For now, the app focuses on LeetCode and CodeForces, which provide comprehensive competitive programming analytics.
