OpenCart vs Square Online

OpenCart is a free, open-source e-commerce platform built on PHP/MVC architecture, offering a robust and customizable foundation without monthly fees.

It is well-suited for both beginners and seasoned developers, providing capabilities such as unlimited products, multi-store management, SEO-ready infrastructure, comprehensive order handling, shipping and payment integrations, and a wide array of extensions.

OpenCart balances affordability and flexibility, making it an appealing choice for those who want full control over their online store without relying on proprietary systems.

Square Online is an all-in-one ecommerce and website builder platform that allows businesses of all sizes—especially those already using Square’s POS system—to build professional online stores with ease.

With drag-and-drop editing, theme templates, custom fonts, and site elements like banners, item badges, and configurable layouts, it gives freedom to control branding and design.

Stores can connect custom domains (in paid plans), remove Square branding, list unlimited products, manage inventory, sync with physical store operations, and integrate with social media and Instagram.
