## What it is
Pogocache is a fast in-memory caching server written in C with a focus on low latency and CPU efficiency. It speaks Memcache, Redis/Valkey (RESP), HTTP, and Postgres wire protocols, and can also be compiled directly into applications as an embedded library.

## Use cases
- fast in-memory key-value cache server
- drop-in replacement for redis or memcached with lower latency
- cache accessible over http with curl
- embed a cache directly into a C application
- reduce cpu cost of caching infrastructure
- low-latency session or object caching

## When to choose
- you need maximum cache throughput and lowest latency per request
- you want redis/memcache protocol compatibility without running redis
- cpu efficiency and operating cost matter
- you want an embeddable single-file cache library

## When to avoid
- you need redis persistence, replication, or rich data structures
- you require a mature ecosystem with long production track record
- you need windows support or cluster sharding features

## Facets
- artifact type: service
- maturity: active
- function: caching, http-server, database
- domain: databases, performance, backend, developer-tools
- platform: self-hosted, cpp
- tags: in-memory-cache, redis-compatible, memcache-compatible, low-latency, embeddable, resp-protocol, postgres-wire-protocol, linux, macos, docker
