PrestaShop

PrestaShop is a mature, open-source e-commerce platform popular in Europe. It offers a high degree of customization through its core software and a marketplace of thousands of modules and themes. The platform is feature-rich out of the box, supporting complex catalogs, multi-store management, and strong international capabilities. Like other self-hosted solutions, it requires technical expertise for setup, hosting, security, and maintenance. The free software can lead to lower long-term costs, but premium modules add expense. It's a strong choice for technically-inclined merchants or developers in its core markets who need a flexible, customizable solution without the SaaS subscription model.
