Nacelle
Nacelle is a composable commerce integration platform that helps you transition to a headless architecture without the typical backend complexity. It acts as a high-speed data orchestration layer, connecting your existing e-commerce platform, content management system, and product information manager into a single, unified GraphQL API.

You can keep your preferred backend tools while gaining the freedom to design unique customer journeys on the frontend. By eliminating the need for custom-coded integrations between every tool in your stack, you reduce technical debt and accelerate your development cycles. It is specifically built for mid-market and enterprise brands that need to improve site performance and developer agility without re-platforming their entire core infrastructure.
