## What it is
Hiredis is a minimalistic C client library for Redis, supporting the binary-safe RESP protocol for Redis >= 1.2. It provides synchronous, asynchronous, and reply-parsing APIs, with a decoupled stream parser reusable in higher-level language bindings.

## Use cases
- connect to redis from c
- send redis commands from a c application
- parse redis replies efficiently
- build redis bindings for another language
- use async redis client in c

## When to choose
- you need a lightweight, low-level Redis client in C or C++
- you are building language bindings for Redis and need an efficient reply parser
- you need synchronous or asynchronous Redis access with minimal dependencies

## When to avoid
- you want a high-level client with explicit methods for every Redis command
- you are working in a higher-level language with an official Redis client
- you need Redis features like clustering handled automatically out of the box

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, parser, http-client
- domain: databases, developer-tools, backend
- platform: c, cpp, windows, cross-platform
- tags: redis, resp-protocol, c-client, async-api, reply-parsing, linux, macos
