Choose LangGraph Platform if...

Engineering teams that picked LangGraph for complex stateful agents and want managed deployment without running Postgres, queues, and auth themselves.

Avoid LangGraph Platform if...

Teams not already on LangGraph — switching frameworks for the hosting isn't worth it. Consider Modal or custom infra.

Choose LlamaIndex if...

Developers building question-answering systems over enterprise documents, databases, or APIs. The go-to for production RAG pipelines.

Avoid LlamaIndex if...

Simple single-document Q&A — a direct Claude or GPT API call with the document in context is simpler.
