Redis

In-memory data store for caching, sessions, and real-time data

Live preview of redis.io

Overview

Redis sits between your application and your primary database, serving as a high-speed cache and data structure store. By keeping frequently accessed data in memory, Redis reduces database load and delivers sub-millisecond response times for read-heavy workloads.

Beyond caching, Redis supports rich data structures - sorted sets, streams, pub/sub, and geospatial indexes - that enable patterns difficult to implement with traditional databases. Leaderboards, real-time analytics, rate limiting, and job queues all map naturally to Redis data structures.

Redis has become infrastructure that virtually every production application needs at some scale. Whether through managed services like Upstash (serverless Redis) or self-hosted deployments, adding a Redis layer is one of the highest-impact performance optimizations you can make.

Why We Recommend Redis

Redis is a standard part of our production architecture. For caching, session management, and rate limiting, nothing matches its combination of speed, simplicity, and data structure versatility.
