Crystallize
Crystallize is a hosted, composable commerce platform that brings product data, content, media, and commerce into a shared model, admin, and API. Its commerce engine covers product and pricing models, subscriptions, customer hierarchies, fulfillment pipelines, and checkout analytics. APIs and webhooks connect external ERP, CRM, payment, and logistics systems. GraphQL and MCP interfaces let AI agents read catalogs, draft quotes, configure subscriptions, and fill carts. The headless platform supports frontends for web, mobile, kiosks, and other platforms; listed platforms also include API, macOS, and Windows. Crystallize lists integrations with payment gateways including Stripe, Klarna, Vipps, Dintero, Adyen, Mollie, Montonio, Quickpay, Two, and Razorpay. It offers a free plan and paid plans from $949/mo; the Atom plan is $949 a month, billed plus metering. Particle and Atom have one tenant per project, while Crystal includes three. Crystallize says it complies with GDPR and CCPA.
Solidus
Solidus is an eCommerce platform for brands that need control over storefronts, business logic, and administration. Its open architecture and API let businesses tailor all three, including for distinctive digital experiences or complex enterprise integrations. Catalog tools include dynamic variants, segmented pricing, product drops, bundles, rich taxonomies, and personalization quizzes. Inventory and fulfillment features cover backordering, split shipments, global fulfillment, WMS or 3PL connections, exchanges, and self-serve returns. Tax support includes per-product rules, VAT, GST, sales tax, automated filing, refunds, and customer exemptions. Businesses can configure promotions and checkout, from time-based offers to one-click or multistep flows. A native subscription engine connects payment methods, promotions, checkout, and fulfillment. Solidus runs via API, on the web, or self-hosted, and supports multichannel sales. The DIY Edition is free; businesses supply their own infrastructure. No transaction fee is listed, and abandoned cart recovery is not available.
