## What it is
SimplCommerce is a free, open-source, cross-platform e-commerce system built on .NET with a modular (modulith) architecture. It provides a storefront and admin back-office with product variations, multi-vendor support, theming, localization, payments, shipping, coupons, and tax configuration.

## Use cases
- build an online store with .NET
- self-hosted multi-vendor marketplace platform
- open source shopping cart in C#
- e-commerce site with Stripe or PayPal payments
- modular ASP.NET Core storefront with admin panel
- run an ecommerce platform on Linux with PostgreSQL
- customizable storefront themes and localization

## When to choose
- you want a .NET-based, self-hosted e-commerce platform
- you need modular architecture you can extend with your own modules
- you need multi-vendor/marketplace features out of the box
- you want cross-platform deployment with SQL Server, PostgreSQL, MySQL, or SQLite

## When to avoid
- you need a headless-only commerce API without a bundled storefront
- your stack is Node.js, PHP, or Ruby
- you need a fully SaaS-hosted solution with managed operations
- you require a very large plugin/marketplace ecosystem like Shopify or WooCommerce
