What are the advantages of Opencart 4 over Opencart 3?

The advantages of Opencart 4 over Opencart 3 are quite apparent to all its users. It is undoubtedly a superior version in many aspects. Some of its most important advantages are:

Loading speed: 

It is faster and lighter than Opencart 3, which improves the loading speed and performance of the online store. This is because it uses PHP 8.1 or higher, which is more efficient and secure than PHP 7.1 or lower. Additionally, it has an improved cache system that reduces the number of queries to the database.


It uses HTTPS by default, which encrypts the communication between the server and the browser. Additionally, it has an improved backup system that allows restoring the online store in case of problems.


It is more flexible and customizable than Opencart 3, allowing the online store to be adapted to the preferences and needs of each client. This is because it uses Twig as a template engine, which is more powerful and easier to use than PHP. Additionally, it has an Event System that allows modifying the behavior of the software without altering the source code.


It facilitates integration with other services and platforms. This is because it uses a RESTful API architecture, which is a communication standard between systems. Additionally, it has an automatic update system, which allows installing the latest versions of the software without losing data or configurations.

How to choose between Opencart 3 and Opencart 4?

Although Opencart 4 has many advantages over Opencart 3, it doesn’t mean that it’s the best option for all cases. Both versions have their benefits. 

OpenCart 4 offers significant improvements in security, performance, user interface, product management, and mobile device compatibility. However, the choice between OpenCart 3 and OpenCart 4 will depend on your specific needs and preferences. If you’re looking for a modern, reliable, and highly functional e-commerce platform, OpenCart 4 might be the best choice for you.

In conclusion, Opencart 4 is a superior version to Opencart 3 in many aspects, but not all. Depending on the budget, time, and experience available, it may be convenient to choose one or the other version for your online store. 

The important thing is to know the characteristics, differences, and advantages of each version before making a decision.
