In-memory data structures
Well-known as a "data structure server", with support for strings, hashes, lists, sets, sorted sets, streams, and more.Learn more →
Server-side scripting with Lua and server-side stored procedures with Redis Functions.Learn more →
A module API for building custom extensions to Redis in C, C++, and Rust.Learn more →
Keeps the dataset in memory for fast access, but can also persist all writes to permanent storage to survive reboots and system failures.Learn more →
Horizontal scalability with hash-based sharding, scaling to millions of nodes with automatic re-partitioning when growing the cluster.Learn more →
Replication with automatic failover for both standalone and clustered deployments.Learn more →
Real-time data store
Redis' versatile in-memory data structures enable building data infrastructure for real-time applications that require low latency and high-throughput.
Caching & session storage
Redis' speed makes it ideal for caching database queries, complex computations, API calls, and session state.
Streaming & messaging
The stream data type enables high-rate data ingestion, messaging, event sourcing, and notifications.
Redis Stack extends Redis with modern data models and processing engines to provide a complete developer experience. Download the source, install using your favorite package manager, or spin it up for free in the cloud.
Redis Stack Server lets you build applications with searchable JSON and time series data models, and extended probabilistic data structures.
Get productive quickly with the Redis Stack object mapping and client libraries.
Visualize and optimize your Redis data with RedisInsight.
Redis Stack use cases
Index and query Redis data structures and data models; run complex aggregations and full-text search on your Redis data.
Model domain entirely in Redis, and query your JSON data efficiently without ever having to use a cache.
Ingest continuous readings from devices in the field, storing as time series data or analyzing and deduplicating with probabilistic data structures.
Identity and resource management
Define digital resources and ACLs as a graph, and compute permissions in real-time with a single Cypher query.
Vector similarity search
Query vector embeddings to power images search, recommendation engines, and natural language text processing.
All the tools to detect fraud in real time, probabilistic queries, vector search, and even processing using streams.
