About Redis Stack

Redis Stack extends the core capabilities of Redis OSS and provides a complete developer experience for debugging and more.

Redis Stack is the best starting point for working with Redis. We’ve bundled together the best of the technology that we have to offer into an easy-to-use package.

In addition to all of the features of Redis OSS, Redis Stack supports:

• Probabilistic data structures
• Queryable JSON documents
• Querying across hashes and JSON documents
• Time series data support (ingestion & querying), including full-text search
• Graph data models with the Cypher query language

Why Redis Stack?

Redis Stack was created to allow developers to build real-time applications with a backend data platform that can reliably process requests in milliseconds or less. Redis Stack does this by taking the original Redis OSS as the core and enhancing it with modern data models, data processing tools, and continuing to fight complexity at every turn. Ultimately, the goal of Redis Stack is to build a real-time data platform that continues to fulfill the philosophy of Redis OSS: simplicity, performance, and reliability.

Redis Stack unifies and simplifies the developer experience of Redis by offering all the cutting-edge capabilities provided by the leading Redis modules. Redis Stack bundles the following capabilities into Redis: RedisJSON, RediSearch, RedisTimeSeries, and RedisBloom.

The overarching vision is to provide developers with a powerful platform for all real-time data use cases. As we continue to advance the capabilities of Redis beyond caching, Redis Stack is the place to start. Redis Stack delivers the core capabilities developers love about Redis and goes beyond to help you build modern applications where performance is paramount.

Redis Insight

The best way to get started with Redis Stack is with Redis Insight, a visualization tool for understanding and optimizing Redis data.

RedisInsight allows you to:

• View data structures visually with the Browser tool and group keys according to their namespaces.
• Use CRUD on most Redis Stack data structures.
• Leverage Workbench, an advanced command-line interface with intelligent command auto-complete and complex data visualizations.
• Analyze traffic to Redis in real time using the Profiler tool.
• Use embedded Redis CLI at any time.
• Analyze memory usage with the Memory Analysis tool.
• Identify and troubleshoot bottlenecks using the Slowlog tool.

Redis Stack packaging

There are two distinct Redis Stack packages to choose from:

• Redis Stack Server: This package contains Redis OSS and module extensions only. It does not contain RedisInsight, the developer desktop application. This package is best for production deployment and is intended to be a drop-in replacement (for example, if you’re already deploying Redis OSS as a cache). You can still download RedisInsight separately.
• Redis Stack: This package contains everything a developer needs in a single bundle. This includes Redis Stack Server (Redis OSS and module extensions) along with the RedisInsight desktop application (or part of the docker container). If you want to create an application locally and explore how it interacts with Redis, this is the package for you.

Use cases

Note: Modules as described here are generic, and we list only the representative use cases.

Clients

Several Redis client libraries support Redis Stack. These include redis-py, node_redis, NRedisStack, and Jedis. In addition, four higher-level object mapping libraries also support Redis Stack: Redis OM .NET, Redis OM Node, Redis OM Python, Redis OM Spring.

Redis Stack license

Redis Stack is made up of several components, licensed as follows:

• Redis Stack Server, which combines open source Redis with RediSearch, RedisJSON, RedisGraph, RedisTimeSeries, and RedisBloom, is dual-licensed under the Redis Source Available License (RSALv2 and the Server Side Public License (SSPL). A breakdown of licensing by Stack component versions is shown in the table below. For more information about Redis licensing, see Licenses.
• RedisInsight is licensed under the SSPL.

Versions and licenses

Since November 15, 2022, our default binary distributions of Redis Stack and our Redis modules are dual-licensed under RSALv2 and SSPL. When using the source code, you can apply either RSALv2 or SSPLv1.
