Aimeos vs Crystallize

Aimeos is an open-source PHP e-commerce framework for Laravel and TYPO3, for building online shops, headless frontends, marketplaces and B2B platforms. Core packages are free for commercial use, with no recurring license fees for self-run stores or client projects. Commerce features include product variants, bundles, vouchers, downloads, events, subscriptions, recurring payments and configurable goods. The framework supports multi-vendor, multi-channel and multi-warehouse operations, as well as multiple tenant shops in one installation. Custom storefronts and apps can use its JSON:API REST API and GraphQL admin API. Aimeos lists more than 100 payment providers through Omnipay and support for MySQL, PostgreSQL, Oracle, Microsoft SQL Server and DB2. Its stated capacity is up to 100,000 products out of the box with standard MySQL, and more than one billion with SOLR or Elasticsearch. Security features described include reviewed code, SQL injection allowlists and Content Security Policy support. Paid support has a 12-month minimum and does not cover implementation or custom development.

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.
