LangChain vs LangGraph: Which Should You Choose?
Founders and CTOs ask about LangChain vs LangGraph constantly. The right answer depends on your team, timeline, budget, and product — not Twitter opinions. Here is a practical decision framework for $10K+ projects.
LangChain
Best when your team, ecosystem, or existing codebase already aligns with LangChain. Consider hiring senior help if production quality or AI integration is on the critical path.
LangGraph
Best when LangGraph solves a specific constraint — performance, hiring pool, or vendor requirements. Validate with a scoped POC before committing full product build.
Decision checklist
- → What does your team already know?
- → What is your App Store / launch deadline?
- → Do you need AI, RAG, or complex backend integration?
- → What is the cost of a 3-month rewrite if you choose wrong?
