Reliable at scale: Redis vs Memcached
Redis and Memcached are both in-memory key-value data stores, but we offer more features, flexibility, and speed. Learn how our multi-model database handles caching plus a range of use cases, including session stores, messaging, and real-time operational data storage.
Why choose Redis over Memcached?
Redis offers superior in-memory data storage with advanced features and better performance for modern applications. Memcached may serve your basic caching needs well, but you probably need more; when it comes to Memcached alternatives, Redis universally comes to mind. Redis’s versatility and reliability make it ideal for session management, real-time data operations and much more.

A closer look at the features
Offers low latency but lacks clustering and replication, limiting scalability to smaller, simpler legacy apps.
