Leetboard is a free and open-source chrome extension developed by RedPhantomDev. It allows you to track and follow your friends' progress on LeetCode, a popular platform for practicing coding interview questions. Acting as a leaderboard, Leetboard provides insights into the number of questions your friends have solved, categorized by difficulty level (easy, medium, hard).

To get started, you can install the Leetboard extension through the Chrome Web Store or by visiting the available GitHub link. Once installed, simply click on the extension and wait for a few seconds as it fetches data from your friends' profiles on LeetCode.

Using Leetboard, you can easily add friends by entering their LeetCode ID into the input bar provided. To delete a friend, simply click on the bar displaying your friends' statistics. If you want to clear all your friends from the storage, there is an option to delete all of them at once.

Stay connected with your coding friends and keep track of their progress on LeetCode using Leetboard.
