OpenCart is a free, open-source ecommerce platform for building online stores with products, categories, payments, shipping and order management. It suits small and medium-sized retailers that want a widely used, self-hosted shop with a large marketplace of extensions.
What is OpenCart?
OpenCart is ecommerce software that lets you create and manage an online shop. It provides the main tools needed to list products, organise categories, accept payments, calculate shipping, manage stock and process orders from one administration area.
Unlike a hosted ecommerce service, the software is installed on your own web hosting account. This gives you more control over the site files, database, design and integrations, but it also means that hosting, updates, backups and security need to be managed properly.
The core software is free and open source. You can learn more about its platform features and current project information on the official OpenCart website. As of 2026, the main cost is not a software licence. It is the hosting, design work, extensions and technical support your shop may require.
5 Best Features of OpenCart
-
Free, open-source core
The main platform can be downloaded and used without a monthly software subscription. There are no OpenCart transaction charges, although your payment provider may still charge its normal processing fees.
This makes it appealing to a retailer who wants to control long-term costs and avoid being tied to one hosted ecommerce provider.
-
Straightforward catalogue management
You can create products, categories, manufacturers, options, attributes, discounts and special offers. The administration area also supports stock control and order information.
For a small retailer, this means everyday tasks such as changing a price, adding a product image or checking an order can be handled from one central dashboard.
-
Wide extension marketplace
OpenCart has a large marketplace covering payment gateways, delivery services, accounting tools, email marketing, search engine optimisation, themes and reporting. Many extensions are free, while paid options vary in price and licensing terms.
The benefit is flexibility. You can start with the core shop and add functionality as the business develops, rather than paying for advanced features before you need them.
-
Multi-store and international selling
The platform supports multiple storefronts from one administration installation. It also includes support for different currencies, languages, tax rules and customer groups.
This can be useful when a retailer operates separate brands, targets different markets or needs distinct catalogues for business and consumer customers. However, multi-store arrangements require careful configuration and testing.
-
Useful built-in selling tools
Core tools include product reviews, coupons, vouchers, customer accounts, order histories, affiliate management and sales reporting. You can also connect the shop to external services through extensions and integrations.
These features give a small business a solid starting point for promotions and customer management. More advanced marketing automation or detailed reporting will usually require additional software.
OpenCart in Action: 3 Examples
1. A specialist product shop
Example scenario: A small business sells specialist tools and replacement parts. It uses categories for different equipment types, product options for sizes and a delivery extension for weight-based shipping.
The owner can manage stock, display technical specifications and review orders without maintaining separate spreadsheets for every product line. A search-friendly structure can also make it easier for customers to find specific items.
2. A growing retailer with several sales channels
Example scenario: A retailer has a main consumer shop and a separate trade catalogue. It uses the multi-store capability to present different prices, product ranges and terms while managing the stores from one installation.
This arrangement can reduce duplicated administration. It should be planned carefully, particularly where stock, customer accounts, payment methods and reporting need to remain separate.
3. A business selling physical and downloadable products
Example scenario: A business sells printed guides alongside downloadable templates. Physical products use delivery options, while digital products are made available after payment.
The platform can support both product types in one shop. The owner still needs to check file protection, delivery emails, refunds and customer support processes before launch.
3 Things That Could Be Better
-
It is not completely hands-off
Self-hosting gives you control, but it also creates responsibilities. You need a suitable hosting environment, regular backups, security checks and a sensible update process.
A non-technical site owner may find this more involved than using a fully managed ecommerce service. Reliable hosting and practical support can reduce the workload, but they do not remove the need for good administration.
-
Extension quality can vary
The marketplace is a major strength, but extensions are supplied by different developers. Their documentation, compatibility, support and update schedules may differ.
Before installing an extension, check its compatibility with your platform version, recent update history, support arrangements and reviews. Test it on a staging copy where possible. Too many overlapping extensions can also slow a shop or create conflicts.
-
Advanced changes may need technical help
Basic configuration is approachable, but complex design changes, payment integrations, multi-store structures and data migrations may require a developer.
This is particularly important for a shop that already receives orders. Poorly tested changes can affect checkout, stock levels or customer records. Build technical support into the budget if the shop is commercially important.
Top 2 Alternatives to OpenCart
- PrestaShop: PrestaShop is another open-source ecommerce platform with a broad extension ecosystem. It can be a strong alternative for retailers that prefer its administration interface, themes or available integrations.
- CubeCart: CubeCart is a smaller ecommerce application in the Ecommerce category of Zest City’s 79-app library. It may suit a simpler shop that does not need the same breadth of marketplace options.
The better choice depends on the catalogue size, required integrations, design expectations and the level of technical support available. It is sensible to test the administration experience before committing to a migration.
3 Tips to Get More From OpenCart
-
Plan the catalogue before adding products
Create a clear category structure and decide how product options, attributes, brands and filters will work. Use consistent product names, descriptions and image sizes.
A well-planned catalogue improves customer navigation and makes future product imports easier. It also provides a cleaner foundation for search engine optimisation.
-
Install fewer, better extensions
Start with the core requirements: payment, delivery, tax, backups, analytics and any essential accounting or stock connection. Add other extensions only when there is a clear business case.
Keep a record of each extension, its purpose, version and renewal terms. Remove unused modules and test updates before applying them to the live shop.
-
Measure checkout performance
Place test orders from a mobile phone and desktop computer. Check product search, basket updates, payment, delivery charges, confirmation emails and refunds.
Review analytics for product views, basket abandonment and completed orders. If customers leave at the payment stage, investigate speed, trust information, delivery costs and payment options before changing the whole website.

FAQs
Is OpenCart free?
Yes. The self-hosted core software is free and open source, with no OpenCart monthly licence fee. You may still pay for web hosting, a domain, premium themes, extensions, payment processing and professional support.
Is OpenCart good for small businesses?
OpenCart can suit small businesses that want control over their online shop and are comfortable using self-hosted software. It is most suitable when the owner has access to reliable hosting or someone who can handle updates, backups and troubleshooting.
Can OpenCart handle many products?
Yes. It is designed to manage sizeable product catalogues, categories, stock records and orders. Actual performance depends on hosting resources, database configuration, theme quality, image sizes, extension choices and the way the catalogue is structured.
Is OpenCart good for beginners?
A beginner can install and configure a basic shop, especially with a one-click hosting installer. However, payment, tax, delivery, security and extension settings require care, so a completely non-technical owner may benefit from guided setup and ongoing support.
Zest City Web Hosting can provide a practical starting point for an OpenCart shop, but your choice should reflect the store’s products, traffic, integrations and plans for growth.
