## What it is
PycURL is a thin Python binding over the libcurl multiprotocol file transfer library, exposing HTTP/HTTPS, FTP, SSL, proxies, authentication, WebSockets, and libcurl's multi/share interfaces. It is very fast and feature-rich but has a low-level, C-like API aimed at advanced developers.

## Use cases
- make fast http requests from python
- download files over ftp or sftp in python
- handle dozens of concurrent connections efficiently
- use proxies and custom ssl certificates with python http client
- integrate curl into an asyncio or tornado ioloop
- upload multipart forms from python
- websocket client in python

## When to choose
- you need maximum performance for many concurrent transfers
- you need libcurl's advanced features like NTLM auth, proxies, or multiple protocols
- you want low-level socket control or integration with a custom event loop

## When to avoid
- you want a simple, Pythonic requests-like API
- you prefer a pure-Python dependency
- you are not familiar with libcurl's C API and its learning curve

## Facets
- artifact type: library
- maturity: stable
- function: http-client, websocket, networking
- domain: web-development, developer-tools, networking
- platform: python, windows, cross-platform
- tags: libcurl, curl-bindings, file-transfer, asyncio, ssl, proxy, ftp, low-level, linux, macos
