BL EPlatforma is a Chrome extension developed by EPlatforma.PRO that aims to speed up the process of listing auctions on Allegro through the Baselinker system. With this extension, users no longer have to manually fill in details such as name, price, category, and parameters. The system retrieves this information from the best-positioned Allegro auctions. Users only need to set the data that the system couldn't find on Allegro based on the EAN code.

The extension offers several features, including downloading the name, price, and parameters from the best-positioned auctions, as well as suggested categories for the product. It also allows users to retrieve data based on parameters, EAN codes, or product names. Additionally, BL EPlatforma automates the process by retrieving data for hundreds of products with just one click and populating the form in the Baselinker system. The extension also includes price control, comparing auction prices with warehouse prices, and name compatibility control, analyzing the original product name and the name on Allegro.

BL EPlatforma complies with Baselinker's regulations, prohibiting the use of scripts, bots, and other similar tools. The extension operates solely on the user's browser side, using the EPlatforma and Baselinker APIs.
