On its website, Medusa is described as an open source Shopify alternative. With the headless engine, flexible e-commerce systems can be set up and operated.
Developers can thus easily and effectively implement scalable and individual e-commerce systems that can be used for companies of all kinds. The Medusa community is very active and helps to drive the project forward. There are no fees for using Medusa, but there is an option to get premium support.
Integrating an SMS dispatch in Medusa is easy with the sms77-Plugin.
