You Own the Whole Store
GrandNode is an open-source e-commerce platform built on .NET Core and MongoDB. No licence fee, no percentage of every transaction, and full access to the source — so nothing about your store is off-limits to change.
The MongoDB foundation makes it unusually comfortable with messy, variable product data — catalogues where every product type has different attributes, which is exactly where rigid relational schemas start to hurt. It's API-first, so it works headless behind a custom storefront.
No Cut of Your Revenue
Open source. As sales grow, your platform bill doesn't grow with them.
MongoDB Under the Hood
Flexible schemas for catalogues where products genuinely aren't all alike.
Headless-Ready
API-first, so your storefront can be anything — Next.js, a mobile app, a kiosk.
End-to-End GrandNode Services
Store builds, plugins, migrations and the performance work afterwards.
Store Builds
Complete GrandNode stores — catalogue, checkout, payments, shipping and tax configured for your market.
Custom Plugins
Behaviour the platform doesn't ship: pricing rules, workflows, bespoke payment and shipping providers.
Multi-Store & Multi-Vendor
Run several storefronts, or a marketplace with independent vendors, from one installation.
Headless Commerce
GrandNode as the commerce engine behind a custom Next.js, React or mobile storefront.
Migration
Move from Magento, WooCommerce or a hosted platform — with products, customers and order history intact.
Performance & Upgrades
Caching, MongoDB indexing and version upgrades for stores that have grown heavy.
