LangChain
Pros
- Maximum flexibility
- Full control over logic
- Massive ecosystem
- Production-ready
Cons
- Requires coding skills
- Steep learning curve
- More boilerplate
Dify
Pros
- No-code visual builder
- Quick prototyping
- Built-in RAG and agents
- Self-hosted or cloud
Cons
- Limited custom logic
- Less extensible
- Not ideal for complex agents
Verdict
LangChain gives total control for complex, production systems. Dify is faster for prototyping and non-technical teams building AI apps.
When to use which
Use LangChain for complex multi-step agents, custom tool integration, and production-grade systems. Use Dify for rapid prototyping, non-dev teams, and standard RAG apps.
