Important: full platforms, headless backends, and frontends are different
WooCommerce, Bagisto, Shopware, Solidus, and Spree are full store platforms. Medusa and Saleor are headless backends, so you build the storefront yourself. Alokai and Your Next Store are frontend layers, and Alokai needs a separate commerce backend behind it.
Closest to BigCommerce
Medusa, Saleor, and Spree are closest to BigCommerce's headless, API-first side, offering product, cart, and order APIs plus a dashboard. Shopware and Bagisto are closest to a ready-made store with admin, themes, and extensions, and WooCommerce is the most familiar choice for WordPress sites.
Important: several are open core
Medusa is MIT, except for proprietary Enterprise Edition files that need a commercial agreement. Spree is BSD-3-Clause, with features such as multi-tenant SaaS in a paid Enterprise Edition. Alokai's npm packages are BSD-3-Clause, but its repository has no root license file and the full platform is paid cloud.
License details
Bagisto, Shopware, and Your Next Store are MIT. Saleor, Solidus, and Spree are BSD-3-Clause, and WooCommerce is GPL-2.0-or-later. Medusa is MIT with proprietary Enterprise Edition materials.
Maintenance status
Medusa, Bagisto, Saleor, Spree, WooCommerce, Your Next Store, Solidus, and Shopware were all updated within days of this update. Alokai's last commit was in April 2026 and its last tagged release was in April 2025, so its development is slower.
