LeetCommit

About

LeetCommit is an automated synchronization tool designed to streamline the workflow between LeetCode and GitHub. It eliminates the need for manual code management by silently capturing accepted submissions and pushing them directly to your designated GitHub repository in real-time.

Designed with a focus on security, reliability, and architectural best practices, LeetCommit is built for developers who require a seamless and secure integration for their competitive programming and interview preparation workflows.

SECURITY & ARCHITECTURE
Security is a core focus of LeetCommit. Unlike legacy synchronization tools that require users to generate and manually input vulnerable Personal Access Tokens (PATs), LeetCommit utilizes a modern OAuth 2.0 Web Flow. 
• Proxy Architecture: Authentication is routed through a secure Cloudflare Worker proxy, ensuring strict separation of concerns.
• Tokenless Onboarding: Users authenticate directly via GitHub's official OAuth portal. No raw keys are ever handled by the user.
• Client-Side Encryption: Active session tokens are encrypted at rest within the local browser environment using AES-GCM-256 cryptographic standards.
• Zero Tracking: LeetCommit operates entirely locally. Source code and metrics are transmitted exclusively between the LeetCode client interface and the GitHub API.

CORE CAPABILITIES
• Real-Time Interception: Hooks into native browser network requests (fetch/XHR) to capture submissions at the exact moment of execution, eliminating the need for page reloads or DOM polling.
• Resilient Background Queue: Engineered with an alarm-driven background service worker. If a network disruption occurs or GitHub API rate limits are exceeded, submissions are safely queued locally and automatically retried.
• Advanced Repository Routing: Full support for syncing to personal repositories, GitHub Organizations, and specific branch targets.
• Directory Prefixing: Maintain repository structure by routing code to specific subdirectories (e.g., configuring a "src/leetcode/" prefix).
• Automated Documentation: Dynamically generates and updates a global README.md file in the target repository, featuring aggregated statistics and language distribution metrics.

LeetCommit provides a frictionless, enterprise-grade solution for tracking algorithmic problem-solving progress.
