CF FetchCodes: Learn from Friends' Solutions

Stuck on a CodeForces problem? Unlock the collective wisdom of your circle!

CF FetchCodes is a powerful browser extension designed to supercharge your Competitive Programming journey. It seamlessly integrates into the CodeForces problem page, allowing you to instantly view accepted solutions from your friends without ever leaving the tab.

Whether you are looking for a different approach, an optimization hack, or just inspiration, CF FetchCodes brings your friends' code directly to you.

🚀 New in this Major Update (v25.11.21):

• Smart Accordion UI: Friends are now listed in a clean, scrollable list. Click on a name to expand and reveal their code instantly.
• Safety-First Architecture: We've implemented a "Human-Like" request system with smart jitter and batching. This ensures your account stays safe by preventing API rate-limit flags.
• Intelligent Caching: Code is fetched only when you ask for it and cached instantly. Re-visiting a friend's solution is now instant and requires zero network usage.
• Multi-Language Support: Whether your friend codes in C++, Python, Java, or C#, the syntax highlighter now auto-detects and formats it perfectly.

✨ Key Features:

• 👀 Instant Code Access: See a list of all friends who have accepted the current problem.
• ⚡ Lazy Loading: To save bandwidth and speed up the page, code is only downloaded when you click a specific friend.
• 🎨 Native Syntax Highlighting: Read code comfortably with coloring that matches the CodeForces environment (Supports C++17/20, Python 3, Java, and more).
• 🔗 Quick Navigation: Includes direct links to the original submission and your friend's profile.
• 📊 Progress Status: A real-time progress bar shows you the status of checking your friends' submissions.

🛠️ How to use:

1. Install CF FetchCodes.
2. Navigate to any CodeForces problem page.
3. Look for the "→ Accepted Codes of Friends" box in the right sidebar.
4. Click "Show Codes".
5. Click on any friend's name in the list to expand and study their solution!

⚠️ Important Notes:

• Contest Integrity: To maintain fair play, this extension does not work during live contests. It is designed for practice and upsolving.
• Privacy: You can only view submissions that are public. Private or gym submissions are restricted by CodeForces API rules.
