KongTracker is a Chrome add-on developed by KongTracker that provides users with valuable information about Rumble Kongs on OpenSea. This free tool displays the overall boost and rarity of all Rumble Kongs directly on their cards, making it easier for users to make informed purchasing decisions.

The current solution for tracking boost and rarity of Rumble Kongs on OpenSea is a community-managed Google document, which can be cumbersome to use alongside OpenSea and Rarity.Tools. KongTracker aims to streamline this process by modifying the HTML on OpenSea, offering a front-end skin for the existing platform.

One of the key advantages of KongTracker is that it does not require any logins or store any data. It simply enhances the OpenSea interface by adding the much-needed boost and rarity information to the Kong cards. Users can now quickly assess the value and rarity of Rumble Kongs without the need for multiple tabs or documents.
