# Command reference

> Every HotKV command, grouped by family, with plan and license notes.

URL: https://docs.hotkv.com/commands/


HotKV implements 294 core commands across 25 categories, matching the
Redis command set plus a handful of HotKV-exclusive additions. None of the
core commands require a license or a specific plan. The Enterprise
edition adds commands for AI and LLM workloads, rate limiting, time series,
the feature store, audit, encryption, replication, multi-tenancy,
observability, and licensing. Every command has its own page with syntax,
options, RESP2 and RESP3 replies, examples, and notes on how it compares
with Redis and Valkey; the full list is [below](#all-commands).

## Plans and licenses

The enterprise commands, all except `LICENSE.*`, need a license feature:
on HotKV Cloud it comes with the plan, and On-Premise it comes with your
license. On HotKV Cloud:

- **Performance and Scale** include the AI and LLM commands, rate
  limiting, time series, the feature store, vector snapshots, and
  observability and alerting.
- **Scale** adds the audit log, encryption at rest, replication, and
  multi-tenancy.
- **Starter** includes none of them.

An unlicensed command replies
`-NOLICENSE <feature> requires a HotKV license. Contact sales@hotkv.com`.
Check what your server has with [LICENSE.INFO](https://docs.hotkv.com/commands/license-info/index.md).
Each command page shows what it needs under **HotKV Cloud** and
**On-Premise**.
