Serverless E-Commerce: Medusa, Saleor, and Vendure

E-commerce is the hardest test case for serverless architecture—inventory, payments, user accounts, admin dashboards, cross-session carts. Yet the serverless ecosystem has quietly built a parallel universe that makes it work. We explore three serious contenders: Medusa, Saleor, and Vendure. Each takes a different approach to decoupling commerce logic from monolithic servers, and each reveals a different trade-off between polish and customizability. Plus: the build-it-yourself path with Stripe, headless CMS, and a JSON file.
