## What it is
picoTCP is a small-footprint, modular TCP/IP stack written in C for embedded systems and IoT devices. It is portable to many microcontrollers and operating systems with minimal porting effort.

## Use cases
- add TCP/IP networking to a microcontroller project
- implement embedded IoT connectivity without a full OS network stack
- run a TCP/IP stack in Linux user space via TUN/TAP
- port a lightweight network stack to a new MCU platform
- use IPv4/IPv6 networking on resource-constrained devices

## When to choose
- you need a small, modular TCP/IP stack for embedded or IoT hardware
- you want a portable C network stack that runs on many MCUs and compilers
- you need user-space networking on Linux or Windows via TUN/TAP

## When to avoid
- you need a fully GPL-free commercial license without negotiation
- you target high-throughput server-grade networking rather than embedded devices
- you need a stack with frequent recent releases and active community development

## Facets
- artifact type: library
- maturity: maintenance
- function: networking, embedded
- domain: embedded-systems, iot, networking
- platform: embedded, windows, c, cross-platform
- tags: tcp-ip-stack, embedded-networking, iot, small-footprint, modular, linux
