phase4 vs Tradeshift

phase4 is a free, open-source Java library for sending and receiving AS4 messages. It is designed for manual integration into an existing system, not as a standalone project. Built-in protocol support includes Peppol and CEF eDelivery; documented additional profiles include BDEW, DBNAlliance, eDelivery2, EESPA, ENTSOG, EUCTP, and HR eDelivery. The library supports UBL and API access, and is intended for on-premise deployment. It requires Java 17 or later, with Java 21 or later recommended for performance. Configuration can come from application.properties, system properties, or environment variables; security setup can use JKS or PKCS12 keystores and truststores. AS4 multi-hop and AS4 split and join are not implemented. The project says automated unit and integration tests cover many configurations, while testing against a real remote system is different. Its testing guide says an official Peppol AP certificate is needed to test sending to or receiving from an existing Peppol provider. phase4 uses the Apache 2.0 license.
