Redis
The in-memory data store everyone uses
Databases / Data · OSS/MIT · 76.2k
What's Good
Blazing fast for what it does. Data structures beyond simple key-value unlock powerful patterns. Pub/sub enables real-time features. The ecosystem is massive—every language has a client.
The Catch
Memory-bound storage is expensive at scale. Persistence options have tradeoffs. The licensing changes caused uncertainty. Clustering adds complexity.
Verdict
The default choice for caching and session storage.
