Bagisto supports headless commerce open source principles and follows MACH-inspired architecture, including API-first and modular design. However, it is not a fully MACH-native platform because it is built on a monolithic Laravel core rather than microservices. Despite this, Bagisto can be extended to closely align with MACH architecture by integrating microservices, cloud-native deployments, and decoupled frontends. This makes it a flexible open source headless commerce solution for businesses aiming to adopt MACH principles without full architectural overhaul.
