OpenCart

OpenCart is a free, open-source platform for creating and operating online stores. It provides administration tools for catalogs, customers, orders, payments, shipping, reports, layouts, and store settings.

The software is self-hosted. Merchants download the application, provide compatible web hosting and a database, then manage the storefront through a browser-based administration panel. The source code is released under the GNU General Public License version 3.

OpenCart is suited to businesses that want control over hosting, source code, extensions, and store configuration. It requires more responsibility for updates, security, backups, compatibility testing, and technical support than hosted commerce platforms.

OpenCart includes catalog management for products, categories, options, attributes, downloadable items, stock quantities, and customer pricing. Its order area supports checkout orders, payment details, shipping details, status changes, invoices, and manual order creation.

The platform supports multiple payment methods and shipping methods through built-in modules and marketplace extensions. Its extension architecture covers payment gateways, shipping services, themes, marketing tools, reports, product feeds, analytics, and other modules.

OpenCart supports multiple languages, currencies, customer groups, tax settings, discounts, coupons, affiliate functions, SEO URLs, and multi-store administration. Exact capabilities depend on the installed OpenCart version and extensions.

Developers can extend the platform through modules, events, themes, and OCMOD modifications. OpenCart 4 extensions use the MVC-L structure and can be installed through the administration interface.

The self-hosted OpenCart software is free to download and use. It does not require a recurring software subscription or impose a platform transaction fee according to OpenCart’s official materials.

Merchants still pay separately for web hosting, domains, payment processing, development, maintenance, security services, and optional commercial extensions or themes. OpenCart’s marketplace contains both free and paid extensions.

A conventional free trial does not apply to the self-hosted edition because the core software is free. Users can install it on a test server or use an official demonstration environment where available.

WooCommerce is a comparable open-source commerce option built on WordPress. PrestaShop provides another self-hosted e-commerce platform with a module marketplace. Magento Open Source targets more complex catalogs and development teams. Shopify and BigCommerce are hosted alternatives that reduce server administration but use subscription-based commercial models.
