Dify
Build and orchestrate LLM applications and agentic workflows with visual workflow design, RAG, and knowledge-base management, open source with 139,000+ GitHub stars.
LangChain
Assemble LLM-powered apps and agents from composable building blocks, with LangSmith adding tracing, evaluation, and deployment. Platform rebranded. LangGraph Platform is now LangSmith Deployment.
Bottom Line
Last reviewed: August 2026
Dify and LangChain both sit in Developer Tools, but they're built around different use cases within it. Dify carries the higher rating (4.7 vs 4.4), but a gap that size rarely overrides a real workflow fit on its own.
Choose Dify if…
Best for teams building production chatbots or agent pipelines who want a visual editor instead of raw LangChain code, and its edge is a visual canvas with built-in RAG tooling and observability, reducing development time versus building from primitives. Dramatically faster to build with than coding from scratch, complex workflows can still get hard to debug once wired up.
Choose LangChain if…
Best for developers building custom applications on top of large language models, and its edge is composable chains, agents, and memory abstractions that cut LLM app code from hundreds of lines to dozens. The standard starting framework for LLM app development, expect the API to keep shifting under you.
