Magento + GraphCommerce
Headless changes the storefront boundary.
It does not, by itself, replace the commerce backend. In a GraphCommerce architecture, Magento continues to own the commerce capabilities and operational data while a Next.js storefront uses Magento's GraphQL APIs to deliver the customer experience.

When it earns its place
A distinct storefront can unlock real product work.
Headless is useful when the experience needs independent release velocity, a modern rendering model, richer content composition, or frontend architecture that a traditional Magento theme cannot provide without growing brittle.
What still has to be engineered
The separation creates a contract, not less complexity.
Authentication, cart state, checkout, cache behavior, previews, payment flows, extensions, and deployment ownership all cross the new boundary. They need deliberate failure modes and clear observability on both sides.
