About SimplCommerce

SimplCommerce is an open-source e-commerce system written in C# on .NET. It is described as simple, cross-platform and a modulith, meaning a modular monolith in which features are separated into modules but deployed as one application.

The project provides an online demo with a storefront and an administration area, a Docker image for testing only, and instructions for running on Windows with Visual Studio 2022, .NET 8 and SQL Server, or on macOS and Linux with PostgreSQL and the .NET SDK. A database schema is created with Entity Framework migrations, and the back office is reached at /Admin.
