// Our Verdict
LangGraph is the production standard for stateful agent execution. If your agent handles real data, transactions, or workflows where state continuity matters, LangGraph is the framework to reach for.
Best for: Production agent workloads requiring stateful, deterministic execution with persistence, memory, and durable step logic
// Strengths
Consensus production pick in 2026 across practitioner communities
37.8k+ dependent packages — highest adoption signal in this category
Deterministic execution via state machine graph model
Built-in persistence, memory, and durable execution
Streaming support throughout the execution graph
494+ releases — most active release cadence in this category
// Weaknesses
Steeper learning curve — requires graph and state machine thinking
Tied to LangChain ecosystem as a dependency
LangGraph Cloud adds cost for managed execution at scale
MCP support is via LangChain integrations, not native-first
// Agentic AI Audit
