# ASP.NET Core ecommerce platform **GrandNode is an open-source ASP.NET Core ecommerce platform** built on .NET 10 and MongoDB. It gives you a complete online store - catalog, shopping cart, checkout, payments, shipping and an admin panel - that you host yourself and extend in C#. It is free under the GPL-3.0, with no per-order fees and no closed SaaS between you and your data. B2C shops, [B2B portals](https://grandnode.com/b2b-ecommerce) and [multi-vendor marketplaces](https://grandnode.com/multi-vendor-marketplace) all run on the same codebase, from one installation. ### Why build your ecommerce on ASP.NET Core - **Performance:** ASP.NET Core is one of the fastest web frameworks available, and GrandNode caches the catalog per customer group, so most visitors are served from one cached page. - **Scalability:** run several application instances behind a load balancer with a Redis-synced cache, keep pictures in Azure Blob Storage or Amazon S3, and scale MongoDB as your catalog and order history grow. - **One language end to end:** plugins, themes, integrations and background tasks are all C#, debugged in Visual Studio, Rider or VS Code. - **Cross-platform hosting:** Linux, Windows or macOS, in Docker or Kubernetes, with .NET Aspire and OpenTelemetry for local development and monitoring. - **Long-term support:** .NET LTS releases, and [GrandNode Official](https://grandnode.com/official) LTS releases with 24 months of security fixes. ### A complete ASP.NET Core shopping cart and storefront Everything a store needs to sell is included, not sold separately as modules. - **Catalog:** simple, grouped, bundled, auction and reservation products, with attributes, variants and per-variant stock. - **Cart and checkout:** guest and registered checkout, wishlists, Stripe Checkout, Braintree and cash on delivery, shipping by weight, fixed rate or pickup points. - **Pricing and promotions:** tier and per-customer prices, discounts, coupons, loyalty points and gift vouchers. - **International selling:** many languages including right-to-left, multiple currencies with automatic exchange rates, and tax by country. - **Content and SEO:** pages, blog and a knowledgebase; friendly URLs, XML sitemaps and structured data. - **GDPR tools:** data export, account deletion, cookie consent and privacy-policy acceptance. The full list is on [Features](https://grandnode.com/features), and you can click through the [live demo](https://demo.grandnode.com/). ### One .NET ecommerce platform for B2B, B2C and marketplaces - **B2C:** a fast, mobile-friendly storefront with themes you can override view by view. - **B2B:** customer groups with their own prices, company sub-accounts, sales employees and VAT handling - see [B2B ecommerce](https://grandnode.com/b2b-ecommerce). - **Marketplace:** vendors with their own panel, products and orders - see [multi-vendor marketplace](https://grandnode.com/multi-vendor-marketplace). - **Multi-store:** many stores from one installation, each with its own domains, language, currency and company details. ### Open-source ASP.NET ecommerce you host yourself The source code is on [GitHub](https://github.com/grandnode/grandnode2). You choose where the store runs - your own server, any cloud or a container platform - and you own the code, the database and the customer data. There is no vendor lock-in: if a feature does not fit, you change it. Data lives in [MongoDB](https://grandnode.com/mongodb-ecommerce), a document database that fits product catalogs with many attributes and variants, and grows without schema migrations. ### A C# ecommerce platform built for developers - **Plugins and themes** for payments, shipping, tax, widgets, discount rules and authentication - see [writing a plugin](https://grandnode.com/developers-writing-a-plugin). - **APIs:** a JWT-secured backend API with OpenAPI documentation, and a frontend API for headless storefronts - see [the REST API](https://grandnode.com/developers-rest-api). - **Clean architecture:** layered services, an in-house mediator, domain events and scheduled tasks. - **AI-ready codebase:** the [AI Agent Kit](https://grandnode.com/ai-agent-kit) teaches coding agents how GrandNode is built. Guides for installing, configuring and extending the platform are in the [knowledgebase](https://grandnode.com/knowledgebase). ### Run it in minutes ``` docker run -d -p 127.0.0.1:27017:27017 --name mongodb mongo docker run -d -p 80:8080 --name grandnode2 --link mongodb:mongo grandnode/grandnode2 ``` Open `http://localhost` and the installer guides you through the rest.
