A new project to resume development on the formerly open-source Redis project. We're calling it Valkey, since it's a twist on the key-value datastore.

Valkey is a high-performance data structure server that primarily serves key/value workloads. It supports a wide range of native structures and an extensible plugin system for adding new data structures and access patterns.

The Faster Redis Alternative. A Multithreaded Fork of Redis.
KeyDB is a fully open source database, backed by Snap, and a faster drop in alternative to Redis.

KeyDB is a high performance fork of Redis with a focus on multithreading, memory efficiency, and high throughput. In addition to performance improvements, KeyDB offers features such as Active Replication, FLASH Storage and Subkey Expires. KeyDB has a MVCC architecture that allows you to execute queries such as KEYS and SCAN without blocking the database and degrading performance.

HTTP REST API caching middleware, to be used between load balancers and REST API workers.

A modern replacement for Redis and Memcached.
Dragonfly is a modern in-memory datastore, fully compatible with Redis and Memcached APIs. Dragonfly implements novel algorithms and data structures on top of a multi-threaded, shared-nothing architecture. As a result, Dragonfly reaches x25 performance compared to Redis and supports millions of QPS on a single instance.
