About

HotKV is a commercial, Redis-compatible in-memory data store for application developers and infrastructure teams. Its C++20 server executes commands across multiple CPU cores and supports RESP2/RESP3 clients, persistence, Lua scripting, clustering, key-value workloads, and vector similarity search. Additional modules provide prompt and semantic caching, RAG retrieval, LLM usage and budget tracking, and AI-agent memory; AI modules are available on HotKV Cloud’s Performance and Scale plans and by license for on-premise deployments. HotKV Cloud is a managed service with dedicated instances, while On-Premise runs on x86_64 or ARM64 Linux in a customer’s infrastructure. Redis command and behavior compatibility varies, so teams should verify the commands and features their applications require before migration.
