L'Amigo - LeetCode & Codeforces Friend Tracker & GitHub Sync

LeetCode & Codeforces friend tracker. Auto-sync code to GitHub, compete on custom Leaderboards, and track 50+ Problem Sheets.

L'Amigo is a comprehensive competitive programming and interview preparation tracker designed for developers looking to improve their problem-solving skills. By bringing together the major coding platforms into a single dashboard, it helps you track your progress, compare statistics with peers, and stay motivated. Who is L'Amigo Built For? - University Students: Track your classmates and build healthy competition within your college to stay motivated during placement season. - Job Seekers & Interview Preppers: Consistently practice the right problems to prepare for technical rounds at FAANG and top-tier tech companies. - Competitive Programmers: Keep a close eye on your rating trajectory, analyze your performance on specific graph or dynamic programming topics, and never miss an upcoming rated round. - Open Source Enthusiasts: Developers who want an open, privacy-first tool rather than relying on closed-source, data-harvesting alternatives. Core Features and Capabilities Multi-Platform Tracking Track your problem-solving progress, recent submissions, and daily consistency streaks across LeetCode, Codeforces, and CodeChef in real-time. Full-Page Analytics Dashboard Jump into a massive new dashboard interface to get deep insights into your group's performance. Switch between global feeds, Leaderboards, and curated Problem Sheets. Sheets Tracker (50+ Sheets) Ditch the spreadsheets. L'Amigo now includes 50+ curated problem sheets (Striver A2Z, CP-31, NeetCode, CSES). It automatically syncs with LeetCode and Codeforces APIs to check off your completed problems, and shows you which of your friends have solved them too! Built-in Code Execution IDE No need to open a local code editor or switch tabs. L'Amigo now features a full, built-in IDE powered by Monaco Editor (the same engine behind VS Code). Write, compile, and execute code in multiple languages directly within your dashboard for quick testing and problem solving. Custom College Standings Build and filter custom leaderboards specifically for your university or college. See exactly how you rank against your local peers and classmates. Live Rating Predictor(In Beta Testing rn) Get intelligent, real-time contest rating predictions for Codeforces so you have a clear idea of where you stand before the official rating updates are published. Upcoming Contests Widget Keep track of the competitive programming schedule. The extension features a dedicated widget displaying upcoming rated contests from Codeforces, CodeChef, and LeetCode so you never miss a round. Interactive Leaderboards Rank your tracked friends using three distinct modes: Power Score (combining peak normalized rating & difficulty-weighted solves), Peak Mastery, and Total Solved. Find out who is truly grinding the hardest. GitHub Auto-Sync Automatically back up every successful submission to your personal GitHub repository. Build your developer portfolio and contribution graph in the background without manually copying and pasting code. Deep Analytics Comparison View head-to-head metrics against your peers. Compare Contest Ratings, Global Ranks, and Topic-wise Mastery to see who has a stronger grasp on specific concepts like Dynamic Programming, Graphs, or Strings. Smart Problem Recommendations Find high-quality problems to practice. The extension analyzes what your tracked friends have successfully solved and recommends problems you haven't completed yet. You can interactively filter these recommendations by platform and difficulty. Global Activity Feed Monitor a unified timeline showing recent problem solves, custom Codeforces achievement badges, and daily streaks across all your tracked friends. Rating-Based Heatmaps Visualize your coding journey with interactive heatmaps that break down the problems you and your friends have solved by platform-specific difficulty and rating bands. Native Profile Integration "Track" and "Compare" buttons are injected directly into LeetCode and Codeforces profile pages. You can start tracking a friend's progress with a single click while browsing the web. Codeforces Dark Mode Improve your late-night coding experience with a native dark mode injected directly into the Codeforces website to significantly reduce eye strain. Real-Time Notifications Receive alerts when your friends solve new problems, helping keep you accountable and motivated to maintain your own daily streak. Profile Import and Export Easily manage large lists of friends by importing or exporting your entire tracking list. This makes it simple to share study groups with partners or back up your data locally to switch devices. How to Get Started 1. Install the extension. Once installed, click the "puzzle piece" icon in your Chrome toolbar and click the pin icon next to L'Amigo so you can easily access your dashboard at any time. 2. Visit any LeetCode or Codeforces profile and click the newly injected "Track" button, or add usernames manually inside the extension popup. 3. To enable automatic code backups, navigate to the Settings tab, securely authenticate with GitHub, and select a repository. 4. Open the extension anytime to view your updated dashboard, activity feeds, and recommendations. Privacy and Architecture L'Amigo is built with a strict privacy-first philosophy. All your tracking data, GitHub Personal Access Tokens, and profile preferences are stored locally in your browser's secure offline storage. We do not use intermediary databases, we do not track your browsing history, and we never route your private data through external servers. The extension is entirely free and open source. Frequently Asked Questions Q: Which platforms are currently supported? A: L'Amigo currently supports LeetCode, Codeforces, and CodeChef. We are continually evaluating new platforms to integrate into the tracking dashboard. Q: Is my GitHub Personal Access Token safe? A: Absolutely. Your GitHub token is stored locally in your browser's secure storage. It is never sent to any external servers, and all API calls to GitHub are made directly from your own machine. Q: Will this slow down my browser performance? A: Not at all. L'Amigo is built with highly optimized React architecture and strictly adheres to Chrome's Manifest V3 guidelines. Background processes only run exactly when needed and sleep otherwise to preserve your battery and memory. Q: Do I need to create an account to use the extension? A: No. L'Amigo is entirely account-free. We believe in privacy-first architecture, so all your tracking data, friends lists, and preferences live locally on your device. Q: Will this slow down my browser performance? A: Not at all. L'Amigo is built with a highly optimized, ultra-lightweight Preact architecture (recently rewritten to be even faster) and strictly adheres to Chrome's Manifest V3 guidelines. Background processes only run exactly when needed and heavy components like the IDE are lazy-loaded to preserve your battery and memory.
