Spree

Spree Commerce provides a complete headless ecommerce backend where products, orders, payments, and promotions are managed through typed REST APIs with OpenAPI 3.0 specs and TypeScript SDKs providing autocomplete and type safety. Fifteen years of production history and 15,600+ GitHub stars back a mature ecosystem that ships a production-ready Next.js 16 storefront built with React 19 and Tailwind CSS 4, including multi-region URL routing and Stripe payments supporting Apple Pay, Google Pay, Klarna, and Affirm. Sales Channels model distinct contexts from a single instance: DTC storefronts, wholesale portals, mobile apps, and point-of-sale terminals, each with its own catalog, pricing, and checkout flow. The rules-based promotion engine supports coupon codes, multi-condition discounts, gift cards, and digital product fulfillment. Multi-warehouse inventory tracks stock across locations in real time with reservations and advanced order routing that splits shipments across fulfillment centers. B2B capabilities include customer-specific price lists, storefront access gating, wholesale portals with approval workflows, and quick order forms. The admin dashboard built with Tailwind CSS provides role-based permissions, product management, order processing with refunds, and scaffold generators for custom pages. BSD 3-Clause licensed with zero platform or transaction fees. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
