Open Source ASP.NET Ecommerce Shopping Cart Software
Kartris versions 1.3 and later ship with full source code to most of the software, including pages, usercontrols, masterpages and business logic layer (BLL). There is a small, fast, optimized compiled core.
Since most of the software is now provided as "open source", users are able to make changes ranging from minor tweaks to major modifications. The open source nature of the code also makes patching much easier - in many cases its just a case of overwriting an existing script with a replacement.
Users can opt to leave the software un-compiled when they install on a live site, or to compile before deployment (for potential performance and security gains).
All queries are implemented as stored procedures, all of which can also be edited or modified as required.
The code is provided as vb.net.
Kartris, complete with source code, is completely free to use for sites with up to 500 product versions (SKUs) for sale. A kartris license is required for sites with more than 500 product versions, and the software is capable of handling sites with well over 1 million products.
