BSRMaster is a free Chrome extension developed by Andrea Biancolli. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This extension is designed to help users find the Best Seller Rank (BSR) for Kindle, Paperback, and Audiobooks on various Amazon platforms.

With BSRMaster, users can easily access the BSR, publication date, and price of each version of a book on Amazon.com. The extension also provides clickable BSR links on Audible, redirecting users to the book's page on Amazon.com. Additionally, users can sort the BSR in ascending or descending order by clicking on the BSR column.

One of the standout features of BSRMaster is the ability to check the average parameters of products in the drop-down menu. Users can view the average BSR, running time, reviews, and price for each format. The extension also allows for personalization of BSR colors and values, enabling users to set their own search parameters for the three formats.

BSRMaster prioritizes user privacy, ensuring that no data from users' personal research is shared. It is a safe and reliable tool for authors, publishers, and book enthusiasts who want to track the performance of books on Amazon platforms.
