LangChain4j vs Spring AI for Java developers
summary
Direct comparison of LangChain4j and Spring AI for agentic Java apps shows concrete tradeoffs: LangChain4j is Java vanilla with clear builder patterns and simpler, consistent APIs that made the demo apps and agent flows easy to assemble and extend; Spring AI is aligned with Spring advisors so it fits existing Spring shops, adds more abstraction and boilerplate but integrates with Spring infra and Quarkus, and the Azure / Microsoft AI stack (notably Azure OpenAI) is already positioned for the Copilot crowd.
