# LangGraph + Dapr

Make your LangGraph agents production-ready. These tutorials show you how to add fault tolerance using Dapr.

- [Durable Workflows](https://docs.diagrid.io/getting-started/quickstarts/ai-agents?agentframework=langgraph#1-log-in-to-catalyst) — Make LangGraph agents immune to failures with automatic recovery and replay.
- [Access Policies](https://docs.diagrid.io/develop/agents/langgraph/langgraph-access-policies) — Secure app-to-app communication with zero-trust access policies.

## Why Dapr for LangGraph?

| Challenge | Dapr Solution |
|-----------|---------------|
| Graph crashes lose all progress | **Durable workflows** checkpoint every node |
| Agents tightly coupled, hard to scale | **Pub/sub** decouples communication |
| Chat memory lost on restart | **State store** persists agent memory across restarts |
| Custom retry logic everywhere | **Built-in retries** with exponential backoff |
