Our review
Pros
  • Free and open source with Linux, macOS, API, and self-hosted support
  • Distributed client-side selection with LRU eviction and item expiration
  • Meta protocol adds anti-stampede and stale-serving mechanisms
  • Runs on Windows, macOS, Linux, Docker, and .NET self-hosting
  • Supports persistence, tiered storage, replication, sharding, and failover
  • Works with Redis clients, StackExchange.Redis, and redis-cli
Cons
  • Core servers do not replicate cached data
  • Requires client integration and self-hosted administration
  • Advanced routing depends on the optional built-in proxy
  • Cluster mode requires a separate control plane for failover
  • Leader election is not implemented by the project itself
  • Founded in 2024, so it has less history than established alternatives
