Redis Cloud
Fully managed Redis service with built-in data structures, pub/sub, Streams, and search — ideal for caching, sessions, and real-time features.
Use Cases
Free Tier
30MB free — supports all data structures, pub/sub, and Redis modules
How to Maximize the Free Tier
Redis Cloud's free 30MB tier is tight but usable for caching, session storage, and lightweight queues. The key advantage over Upstash is full Redis protocol support with all data structures (Hashes, Sorted Sets, Streams, etc.). Use TTLs aggressively to prevent key buildup and stay within the 30MB limit. Enable RedisJSON and RediSearch modules for free to add document search and JSON storage without extra services. The free tier doesn't include persistence — treat it as ephemeral cache, not primary storage.
Getting Started
Sign up at redis.io → create a free Essentials database → select a region → copy the connection string → connect with any Redis client (redis-cli, ioredis, node-redis) → test with SET/GET → configure in your app.
Pros
- Full Redis compatibility: 100% Redis protocol compatible — all data structures, commands, and client libraries work unchanged
- Redis modules: Free access to RedisJSON, RediSearch, and RedisTimeSeries modules for document search and analytics
- Sub-millisecond latency: In-memory data store with consistently low latency — ideal for real-time features and caching
Cons
- 30MB storage: 30MB is very restrictive — only suitable for small datasets, not primary data storage
- No persistence on free: Free tier doesn't include data persistence — data loss possible during failures
- Connection limits: Free tier has limited concurrent connections — can bottleneck under traffic spikes
