PrestaShop is an open-source PHP ecommerce platform, popular in Europe and Latin America, that you self-host and customize. The core software is free to download, but a working store typically also needs paid hosting, a theme, and modules for things like SEO, layered navigation, and payment methods — so the total cost adds up even though the license itself is free. Since it's already open source, the reason to look elsewhere is usually the underlying stack rather than pricing: Symfony/Vue-based platforms like Shopware offer a more modern headless architecture and a larger extension ecosystem for teams building custom storefronts.
