langgraph-checkpoint-redis
Redis implementation of the LangGraph agent checkpoint saver and store.
Decision gist · record as of 2026-08-14
Yes, if you are building LangGraph agents and need persistent, scalable checkpoint storage. The package is actively maintained, has low install friction, and solves a real problem for production agent deployments. The main gotcha is the Redis module requirement (RedisJSON, RediSearch)—verify your Redis deployment includes these before installing, especially on Azure or Redis Enterprise.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Redis 8.0+ (or Redis Stack for older versions) with RedisJSON and RediSearch modules enabled; Azure Managed Redis and Redis Enterprise require standard Redis client, not cluster-aware client.
- Low install friction; pure Python wheel with straightforward dependencies.
- Active maintenance (last commit 2026-07-14, 31 days since release).

What it is and what it does
langgraph-checkpoint-redis is a Redis backend for LangGraph's checkpoint and store systems, allowing you to persist agent state and conversation history in Redis instead of memory or local storage. It provides both standard and shallow checkpoint savers (sync and async), plus key-value stores with optional vector search for semantic caching and tool caching in LangChain agents.
The package wraps redis and redisvl to manage checkpoint serialization, TTL-based expiration, and index creation. It handles the complexity of connecting to different Redis deployments—standard Redis, Azure Managed Redis, Redis Enterprise—by detecting cluster mode and configuring clients appropriately. You call .setup() once to initialize indices, then use put/get/list methods to store and retrieve checkpoints keyed by thread_id and namespace.
Use it for
- Store LangGraph agent execution checkpoints in Redis for multi-turn conversation recovery across server restarts.
- Implement semantic caching for LLM tool calls using Redis vector search to avoid redundant API calls.
- Scale agent state across multiple worker processes by persisting checkpoints to a shared Redis instance.
- Expire old conversation history automatically using Redis TTL to manage storage costs.
- Build agent middleware for conversation memory and tool result caching in production deployments.
