LangChain vs. LlamaIndex vs. LangGraph 2026: Die Entscheidungsmatrix

Legacy monolithic chains created unmaintainable spaghetti code. By 2026, the ecosystem fractured cleanly into specialized architectural tiers: cyclical state machines for agent control, and hierarchical graph indices for dense retrieval.

Separation of Concerns: LangGraph vs LlamaIndex

LangGraph provides cyclical state machine execution and checkpoint persistence for autonomous multi-agent loops. LlamaIndex remains the gold standard for dense heterogeneous document ingestion, recursive chunking, and semantic vector retrieval.

02

Cyclic StateGraph Implementation

Design resilient loops with typed dictionaries, conditional router edges, and circuit-breaker iteration caps.

03

The Canonical Enterprise Stack

Modern enterprise architectures standardize on LlamaIndex for knowledge retrieval coupled with LangGraph for execution orchestration.
