Seeking a Robust Open Source eCommerce Marketplace Stack?

Developers building scalable marketplaces need more than templates — they need control. Open source eCommerce platforms like Bagisto (Laravel-based) and Medusa.js (Node.js-based) provide headless architecture, native multi-tenancy, and decoupled frontend/backends. With REST & GraphQL APIs, you can seamlessly integrate with mobile apps, PIMs, or ERP systems. These platforms support custom logic injection, real-time event handling (webhooks/queues), and microservices. Ideal for teams prioritizing performance, extensibility, and full code access — not SaaS limitations.
