X-Cart is an eCommerce platform that is used to create an online store. X-Cart is available both as a downloadable self-hosted licensed software and as a cloud-based cart, hosted by X-Cart team, yet with your full access to the code for customisations.
It supports tons of eCommerce features either out of the box or as a ready-made extension. Installing a new module does not require technical knowledge or access to the server: the marketplace is App Store - like, right within the admin backend of the store.
X-Cart offers 24/7 technical support through phone, email, and a help desk. Besides, you can get a full stack of services directly from the software vendor: custom development, web design, eCommerce hosting and SSL certificates.
