# Checkpointer integrations

> Integrate with checkpointer backends for LangGraph persistence.

Checkpointers enable [persistence](https://docs.langchain.com/oss/python/langgraph/persistence.md) in LangGraph, allowing agents to save and resume state across interactions.

To implement your own checkpointer for a custom storage backend, see [Build a custom checkpointer](https://docs.langchain.com/oss/python/langgraph/checkpointers.md#build-a-custom-checkpointer).
