Strengths
  • + Explicit, debuggable graph model for complex flows
  • + Mature Python ecosystem
  • + Tight LangSmith integration
  • + Extensive data connectors and RAG tooling
  • + Strong document parsing and ingestion (LlamaParse/LlamaCloud)
  • + Agents and event-driven workflows built in
  • + Large ecosystem and integrations
Tradeoffs
  • − Steeper learning curve than linear agent SDKs
  • − LangChain abstractions are opinionated
  • − Broad API surface can be complex to navigate
  • − Heritage is RAG-centric rather than agent-first
  • − Frequent API changes across versions
