valkey
Python client for Valkey forked from redis-py
Decision gist · record as of 2026-08-14
Yes. Valkey-py is actively maintained, has no known vulnerabilities, installs with minimal friction, and provides a complete, production-stable Python interface to Valkey. It is the appropriate choice for any Python application that needs to interact with a Valkey server, whether for caching, sessions, pub/sub, or general key-value operations. The MIT license poses no restrictions.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running Valkey server (e.g., via Docker or local installation) accessible on the specified host and port.
- Low install friction with a single lightweight runtime dependency (async-timeout).
- Active maintenance with recent commits and stable production status across Python 3.9–3.13.

What it is and what it does
Valkey is a Python client library that provides a complete interface to the Valkey key-value store, a fork of Redis. It exposes all standard Valkey commands through native Python methods, handles connection pooling automatically, and supports both synchronous and asynchronous workflows. The library includes built-in support for advanced features like pipelining (batching commands to reduce round-trip overhead), pub/sub messaging, and RESP3 protocol negotiation.
The package is designed as a drop-in replacement for redis-py, with backward-compatible aliases available for a smooth migration path. It depends only on async-timeout for its core functionality and optionally integrates a compiled response parser (libvalkey) for improved performance when available. The library supports modern Python versions (3.9 through 3.13) and runs on both CPython and PyPy.
Use it for
- Build a session store or cache layer for web applications using synchronous or async connection pools.
- Implement real-time messaging or event distribution using pub/sub channels.
- Batch multiple database operations into a single round-trip using pipelines to reduce latency.
- Migrate existing redis-py code to Valkey with minimal changes using provided compatibility aliases.
- Store and retrieve structured data (strings, hashes, lists, sets) in a high-performance key-value store.
