Curl-cffi is a Python library for implementing curl-impersonate which is a HTTP client that appears as one of popular web browsers like: - Google Chrome - Microsoft Edge - Safari - Firefox Unlike requests and httpx which are native Python libraries, curl-cffi uses cURL and inherits it's powerful features like extensive HTTP protocol support and detection patches for TLS and HTTP fingerprinting.

Using curl-cffi web scrapers can bypass TLS and HTTP fingerprinting.

hrequests is a feature rich modern replacement for a famous requests library for Python. It provides a feature rich HTTP client capable of resisting popular scraper identification techniques: - Seamless transition between headless browser and http client based requests - Integrated HTML parser - Mimicking of real browser TLS fingerprints - Javascript rendering - HTTP2 support - Realistic browser headers

Example Use


curl-cffi can be accessed as low-level curl client as well as an easy high-level HTTP client:
from curl_cffi import requests

response = requests.get('https://httpbin.org/json')
print(response.json())

# or using sessions
session = requests.Session()
response = session.get('https://httpbin.org/json')

# also supports async requests using asyncio
import asyncio
from curl_cffi.requests import AsyncSession

urls = [
  "http://httpbin.org/html",
  "http://httpbin.org/html",
  "http://httpbin.org/html",
]

async with AsyncSession() as s:
    tasks = []
    for url in urls:
        task = s.get(url)
        tasks.append(task)
    # scrape concurrently:
    responses = await asyncio.gather(*tasks)

# also supports websocket connections
from curl_cffi.requests import Session, WebSocket

def on_message(ws: WebSocket, message):
    print(message)

with Session() as s:
    ws = s.ws_connect(
        "wss://api.gemini.com/v1/marketdata/BTCUSD",
        on_message=on_message,
    )
    ws.run_forever()
hrequests has almost identical API and UX as requests and here's a quick overview:
import hrequests

# perform HTTP client requests
resp = hrequests.get('https://httpbin.org/html')
print(resp.status_code)
# 200

# use headless browsers and sessions:
session = hrequests.Session('chrome', version=122, os="mac")

# supports asyncio and easy concurrency
requests = [
    hrequests.async_get('https://www.google.com/', browser='firefox'),
    hrequests.async_get('https://www.duckduckgo.com/'),
    hrequests.async_get('https://www.yahoo.com/'),
    hrequests.async_get('https://www.httpbin.org/'),
]
responses = hrequests.map(requests, size=3)  # max 3 conccurency
