One admin panel, many storefronts: Magento Open Source is a free ecommerce platform for selling online under separate domains, category trees, languages, and currencies from a single install. Catalog managers create simple, configurable, grouped, virtual, bundle, and downloadable products and organize them with categories and attribute sets. Merchandisers assemble CMS pages, blocks, and product and category content in Page Builder by dragging rows, columns, tabs, banners, sliders, videos, and product lists onto a visual stage. Catalog price rules and cart price rules with coupon codes drive promotions, and customer groups such as Wholesale and Retailer can get targeted discounts and their own tax class. Shoppers browse the Luma storefront theme and check out as guests or with accounts. Staff then take each order through invoice, shipment, and credit memo, while Multi-Source Inventory tracks stock across warehouses, stores, and drop shippers. Built-in sales, customer, and product reports show what sells, and Login as Customer lets permitted staff view the storefront as an opted-in shopper sees it. Import and export tools move products and customers in bulk, and the REST and GraphQL APIs let ERPs, shipping tools, and headless front ends read and write store data. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. OSL-3.0 licensed.
