CP Code Manager — CacCat

CP code manager is a browser extension that helps developers save their accepted LeetCode solutions directly to a GitHub repository.

When a submission is accepted on LeetCode, the extension detects the submission page, extracts the solution code and related metadata, and uploads it to a user-configured GitHub repository using the GitHub REST API. Users can choose between automatic syncing or manual submission via a lightweight in-page control panel.

The extension works seamlessly with LeetCode’s single-page application navigation and supports multiple programming languages. GitHub authentication is handled using a user-provided Personal Access Token, which is stored locally in the browser and used only for repository access specified by the user.

LeetCode Git Sync is designed to reduce manual effort, keep coding practice well documented, and provide a clean workflow for maintaining a personal archive of solved problems.
