DiceDB is an open-source, low-latency key/value data store forked from Valkey (itself a fork of Redis), written in C. It extends Valkey with query subscriptions via OBSERVE commands and a spill module that transparently persists evicted keys to disk (RocksDB), while remaining fully compatible with Redis and Valkey clients, SDKs, and tooling.

Use cases

• run a redis-compatible in-memory cache
• store datasets larger than RAM with tiered disk spilling
• subscribe to query changes and get real-time push updates instead of polling
• self-host a drop-in replacement for redis or valkey
• use a key-value store for caching and message queues
• migrate existing redis workloads without changing client SDKs

When to choose

• you want Redis/Valkey compatibility with extra features like query subscriptions and disk spilling
• your working set exceeds available memory but hot data must stay in-memory fast
• you need reactive push-based updates to query results in live applications
• you want an open-source (BSD-3-Clause) self-hosted data store deployable via Docker

When to avoid

• you need the mature, battle-tested Redis or Valkey codebase without fork risk
• you rely on features from the archived Go-based legacy DiceDB implementation
• you need strict license clarity - the GitHub license is marked NOASSERTION despite the site claiming BSD-3-Clause
• you need multi-model capabilities like document or graph storage
