Pros and cons of building agent workflows on n8n's visual platform versus LangChain4j 1.18 as a JVM library: integrations and canvas against Apache 2.0, code review, and AgenticServices. Includes the license gate, the experimental agentic module, and the same workflow written both ways.
N8n · What You Get
400+ prebuilt integrations — the glue is the product
Langchain4j 1.18 · What You Get
A library, not a platform: Spring Boot, Quarkus, plain main()
N8n · What It Costs You
✗ Sustainable Use License: internal use only — no reselling, no embedding
Langchain4j · What It Costs You
✗ langchain4j-agentic is experimental — beta28, the API still moves
