GrandNode2 🧰 Platform Open source

GrandNode2 is a free, open-source e-commerce platform built on ASP.NET Core with MongoDB as its data store, rather than the SQL-based stack most competing platforms use. That NoSQL foundation makes it well suited to large, flexible product catalogs and multi-store/multi-vendor setups where schema rigidity becomes a pain point on other systems.

It's self-hosted software you install and run yourself — there's no rev-share, commission, or payout process involved; you keep everything your store earns minus your own hosting and payment-processor costs. The core is GPL-3.0 licensed and free; costs come from server hosting, MongoDB infrastructure, developer time, and any paid themes or plugins you choose to add.

Standout features include native multi-store and multi-vendor (marketplace) support, a plugin architecture for extending checkout, shipping, and payments, and a genuinely active open-source project (regular commits, real community engagement on GitHub) rather than an abandoned fork. For a publisher or small business, GrandNode2 is a solid choice if you're comfortable with — or can hire for — ASP.NET Core and MongoDB, and you want a capable, customizable store without vendor lock-in or platform fees.

It's a weaker fit if you want to launch quickly with no technical involvement, or if you need the enormous third-party app/theme marketplace that Shopify or WooCommerce offer — GrandNode2's ecosystem, while real, is meaningfully smaller. It's general-purpose e-commerce software with no specific vertical focus, and works reasonably well for anything from a small boutique store to a multi-vendor marketplace, provided you have the technical resources to run it.
