Redis is an in-memory data structure store optimized for performance and low latency, making it ideal for caching and real-time analytics. CouchBase, on the other hand, combines the features of a NoSQL database with built-in caching and mobile support, making it more suitable for applications that require complex querying and data synchronization.
