Designed to scale from a single server to hundreds, proven to handle tens of thousands of orders daily with large product catalogs, making it suitable for high-volume e-commerce without vendor lock-in.
The flexible plugin architecture lets developers pick and choose integrations for shipping, taxes, and more, allowing deep customization without modifying core code, as described in the features.
Fully open-source with no vendor lock-in, giving teams complete control over their e-commerce platform and the ability to self-host with Docker and Kubernetes, avoiding proprietary constraints.
Requires Docker, Node.js with specific version constraints (14.18.1 ≤ Node < 16), CLI tools, and SSH authentication, which can be a significant barrier for teams without DevOps experience or seeking quick deployment.
While extensible via plugins, core features like advanced marketing tools or built-in payment gateways may require additional custom development or plugins, unlike all-in-one SaaS solutions that offer more pre-built functionality.
The project currently restricts Node.js to versions between 14.18.1 and below 16, which might conflict with modern development stacks and require extra management for compatibility, as noted in the getting started section.
