Everything You Need
Built-in tools and capabilities to deploy and manage with confidence.
Sub-Millisecond Latency
In-memory data access with sub-millisecond response times. Ideal for caching, session storage, and real-time leaderboards.
Pub/Sub Messaging
Built-in publish/subscribe messaging for real-time features, live notifications, and event-driven architectures.
Persistent Storage
Optional data persistence with RDB snapshots and AOF logging. Your data survives restarts and failovers.
TLS Encryption
All connections encrypted with TLS by default. Private networking available for services within RunSite.
Automatic Failover
Redis instances are automatically restarted on failure and rescheduled to healthy nodes with minimal downtime.
Data Structures
Full Redis data structure support: strings, hashes, lists, sets, sorted sets, streams, and HyperLogLog.
How Redis fits your stack
Redis sits between your application and database, reducing latency and offloading read traffic.
App Checks Cache First
Your application queries Redis before hitting the database. Cache hits return data in sub-millisecond time, avoiding expensive database queries entirely.
Cache Miss → Database Query
On a cache miss, your app queries PostgreSQL, stores the result in Redis with a TTL (time-to-live), and returns it to the user. Subsequent requests are served from cache.
Real-Time Features via Pub/Sub
Use Redis Pub/Sub channels for live notifications, chat messages, or presence indicators. Multiple web service instances subscribe to the same channel for consistent real-time behavior.
Session & Queue Management
Store user sessions with automatic expiration across all your service instances. Use Redis lists as lightweight job queues for background processing without a separate queue service.

Common scenarios where this service shines.
Application Caching
Cache database queries, API responses, and computed results to reduce latency and database load.
Session Management
Store user sessions with automatic expiration. Share sessions across multiple web service instances.
Real-Time Features
Build live dashboards, chat applications, presence indicators, and real-time notifications with Pub/Sub.
Rate Limiting & Queues
Implement API rate limiting, job queues, and task scheduling with Redis lists and sorted sets.

Frequently Asked Questions
Common questions about this service.
RunSite runs Redis 7+ which includes all modern features: Redis Functions, client-side caching, ACLv2, and improved memory efficiency. We upgrade to the latest stable release automatically.
On paid plans, Redis data is persisted using RDB snapshots and AOF (Append Only File) logging. On the Starter plan, data is stored in memory only and will be lost on restart.
While Redis supports persistence, it is optimized for caching and in-memory workloads. For primary data storage, we recommend PostgreSQL. Redis is best used alongside PostgreSQL for caching, sessions, and real-time features.
Add the REDIS_URL environment variable to your web service. RunSite provides both internal (private network) and external connection strings. Internal connections are faster and free of charge.
