About

We build HotKV, an in-memory data store written from scratch in C++20 that speaks the Redis protocol and runs commands on every core of the machine at once. Vector search, a semantic cache for LLM responses and agent memory are part of the server, not add-on modules. We publish our benchmarks against Redis, Valkey and Dragonfly with the harness and the raw data, including the commands we did not win. HotKV Cloud is in free early access. We are based in London.

The benchmarks behind the launch, raw data included, plus the one we didn't win

Everything on the launch page comes from a measurement you can rerun yourself. The harness, the raw memtier output and every flag we set are in the public repo: https://github.com/hotkv-ltd/hotkv

I also recorded two sessions on a single 160 vCPU Azure box, same memtier line, one server after the other, with the load generator on the same machine (so the absolute numbers are lower than the published run):

HotKV - Redis-compatible store that uses every core. AI built in.

A multi-threaded, Redis-compatible in-memory data store written in C++20. Existing clients connect unchanged. Vector search, a semantic cache for LLM response and agent memory run inside the server. Benchmarks with Redis, Valkey and Dragonfly are public.
