## What it is
pyuv is a Python binding for libuv, the high-performance asynchronous I/O and platform abstraction library behind Node.js. It exposes non-blocking TCP/UDP sockets, timers, async DNS and filesystem operations, child processes, and thread pool scheduling through a consistent cross-platform API.

## Use cases
- write non-blocking TCP servers in Python
- perform asynchronous DNS resolution
- watch filesystem events cross-platform
- spawn and manage child processes asynchronously
- schedule work on a thread pool
- build an event loop on epoll/kqueue/IOCP

## When to choose
- you need libuv's event loop and primitives directly from Python
- you want consistent async I/O behavior across Linux, macOS, and Windows
- you need low-level networking, timers, or fs events without a full framework

## When to avoid
- you just want high-level async code - use Python's built-in asyncio instead
- you need an actively developed project - releases are infrequent and Python 2.7-era docs linger
- you want a batteries-included web framework rather than raw event loop bindings

## Facets

- function: concurrency, networking, http-server, websocket
- domain: developer-tools, networking, cross-platform
