## What it is
POCO (Portable Components) is a collection of cross-platform C++ class libraries for building network- and internet-centric applications, covering networking, HTTP, XML/JSON, database access, logging, cryptography, and more. It complements the C++ Standard Library, runs on platforms from embedded to server, and is licensed under the Boost Software License.

## Use cases
- build an http server or rest client in c++
- cross-platform c++ networking library
- connect to mysql, postgresql, sqlite, mongodb or redis from c++
- parse xml and json in c++
- add logging and configuration to a c++ application
- build iot or embedded device software that talks to cloud backends
- implement tls/ssl-secured network communication in c++
- build cross-platform c++ server applications

## When to choose
- you need a comprehensive, portable C++ foundation library for networked applications
- you target many platforms including embedded, mobile, and server from one codebase
- you want mature, battle-tested libraries with 20+ years of production use
- you need integrated networking, database access, XML/JSON, and logging in one dependency

## When to avoid
- you work in a language other than C++
- you only need a single small feature and prefer a lightweight focused library
- you want a modern async-first networking stack like Asio-based frameworks
- you need commercial-grade IoT extensions like MQTT or Modbus, which require the paid POCO PRO/macchina.io products

## Facets
- artifact type: library
- maturity: stable
- function: http-client, http-server, logging, serialization, database-driver, cryptography, json, websocket, email, concurrency, configuration-management, file-system, date-time, networking
- domain: web-development, backend, iot, embedded-systems, networking, developer-tools, cross-platform, databases
- platform: cpp, cross-platform, windows, embedded, iot
- tags: c-plus-plus, boost-license, sql, mongodb, redis, jwt, zip, prometheus, iot-edge, server-applications, xml, linux, macos, mobile, desktop, web-server
