Years ago, Interspire announced that they would no longer actively support their shopping cart. This marked the end of active maintenance for what was once a prominent licensed eCommerce platform. However, a diminishing number of Internet stores are still powered by Interspire shopping cart. That is why merchants got into a situation where they are left without any updates and bug fixes. Consequently, official support for Interspire ceased long ago, leaving merchants without essential updates and bug fixes. So, two logical dilemmas now stand in front of them. First, which cart can effectively replace Interspire, such as Magento or WooCommerce. And second, how to move from current shopping cart to a new one? For comprehensive guidance, consider our Universal eCommerce Migration Checklist.
As they say, the King is dead. Long live the King! So, let us find out who can become a real Interspire alternative.
The HeirWhy Interspire company closed their shopping cart? The answer is very simple - the appearance of BigCommerce. It is a hosted eCommerce platform that was launched in 2009 and that has shown incredible results in eCommerce industry. So, finally company decided to concentrate its efforts and encourage all clients to move to BigCommerce shopping cart. For a detailed guide on this transition, see our BigCommerce Migration Guide. You won’t require any additional skills to manage it. Basically, BigCommerce is a hosted and improved version of Interspire that looks and feels almost the same. You will be able to move your customised templates easily. Technical Support, documentation and official forum are also available. It seems to be the most logical option, because if you liked Interspire you will definitely enjoy BigCommerce.
The Contender
When we talk about BigCommerce the first rival that comes to mind is Shopify. It has almost the same functions including easy product management, customizable template system, SEO friendly links, coupons and discounts, official support and responsive community, etc. Other features that are not out of the box can be added from AppStore. Shopify's advantages over BigCommerce is B2B facilities and newsletter system. However, note that transaction fees may apply, depending on your Shopify plan and chosen payment gateway, which can impact overall costs compared to BigCommerce. In general, Shopify will cost more than BigCommerce. But after simple customisation you will get a web shop with really unique design. And of course, don’t forget about Shopify's readily available trial period, allowing you to thoroughly evaluate its features. For a detailed walkthrough, explore our Migration Preview Service.
North American Successors
Two other alternatives are Shift4Shop and Pinnacle Cart. The first one is a hosted platform known for its social media marketing facilities that include blogging opportunities, tools that allow you to sell on Facebook and create your own Facebook affiliate system, Twitter integration and YouTube video management.
A huge number of people who used Interspire appreciated it for being a licensed solution. After you paid for your shopping cart you could get full control over it. You had an opportunity to modify and copy your store’s database and source code. So, what should you do if you don’t want to use hosted platform? How to get a cart that has the same level of functionality and usability as Interspire had? Just consider Pinnacle Cart. It offers both hosted and licensed solutions and at the same time can even add some marketing tools which were not available with Interspire. Understanding the difference between hosted and open-source platforms can help in making an informed decision.
However, Shift4Shop and Pinnacle Cart have one serious issue to think about. Both platforms are oriented towards North American customers. Shipping gateways such as USPS, FedEx, DHL and Canada Post are very handy for Americans and Canadians. But if you live in Europe or Australia you will have to put a lot of efforts to manage the carts.
Licensed Alternative
Another shopping cart that offers its solution as licensed platform is CS-Cart. It supports almost identical set of features and payment/shipping gateways and it is open source. So, basically it is the most similar to Interspire shopping cart.
There are definitely much more candidates to replace Interspire and which one to choose depends only on you. However, those that were mentioned are the closest alternatives that combine user-friendly and multi-functional interface. After choosing the cart to power your business, you need to migrate your data from your current shopping cart to a new one. For a smooth transition, leveraging services like migration customization can be highly beneficial. To conduct this process quickly and accurately you should consider Cart2Cart.

Monthly Update – January 2026
As we step into 2026, the eCommerce landscape continues its rapid evolution, emphasizing data-driven strategies and enhanced customer experiences. A crucial trend for merchants contemplating a platform migration is the deepening integration of AI and machine learning for predictive analytics and hyper-personalization. Future-proofing your store means choosing a platform that not only handles your current data seamlessly but also scales with emerging AI technologies, allowing for dynamic pricing, personalized product recommendations, and automated customer support.
Another significant focus is on headless commerce architectures. Decoupling the front-end (customer-facing) from the back-end (eCommerce logic) offers unparalleled flexibility, speed, and design freedom, which is becoming increasingly vital for brands seeking truly unique digital storefronts. When migrating, consider if your chosen platform supports or facilitates a headless approach to provide a more agile and scalable solution. Prioritizing mobile-first design and ensuring robust API capabilities for third-party integrations will also be key to staying competitive and future-ready in the year ahead. A strategic migration is not just about moving data, but about embracing the next generation of online retail.
