Kartris is an open-source, ASP.NET e-commerce system written in VB (Web Forms) and with an MS SQL database back end. It is optimized to handle sites with 1,000,000+ SKUs out-of-the-box.
The latest version (v2.5) includes a fully-responsive front end based on Zurb's Foundation platform, enabling mobile and tablet support via a single unified front end.
There is also native Bitcoin support, via a JSON interface with the standard Bitcoin client - no need for third party services to accept Bitcoin.
There is a fully-featured back end to control all aspects of the store. It includes a unified search, treeview navigation and is optimized to handle hundreds of orders per day and a million-plus products.
Kartris is built on a multi-tier model, with database, stored procedures, DAL, BLL and front end. Visual customization is via 'skins', a combination of master pages and CSS. The database is structured with no limit on the number of languages or currencies
that can be used. The database has been optimized so that the software is capable of running stores with well over a million SKUs out-of-the-box. The back end has been refined to handle hundreds of orders per day, and to make managing huge catalogues feasible.
Kartris was previously only available on a proprietary license. From v2 onwards, it is available under both the GPL v2 and the Kartris Commercial License (proprietary).
