Ballerina treats network communication as a first-class concern — services, clients, and data formats (JSON, XML, CSV) are built into the type system. Its graphical sequence diagram view is automatically generated from code, making service interactions visible. It targets integration and API development as a higher-level alternative to Java or Go microservices.
