Installation

pip install pyrua

Quick Start

Basic Usage

from pyrua import get_rua

# Generate a random User-Agent
user_agent = get_rua()
print(user_agent)
# Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.6099.109 Safari/537.36

Browser-Specific User-Agents

from pyrua import get_chrome_ua, get_firefox_ua, get_safari_ua, get_edge_ua, get_opera_ua

# Chrome User-Agent
chrome_ua = get_chrome_ua()

# Firefox User-Agent
firefox_ua = get_firefox_ua()

# Safari User-Agent
safari_ua = get_safari_ua()

# Edge User-Agent
edge_ua = get_edge_ua()

# Opera User-Agent
opera_ua = get_opera_ua()

Device-Specific User-Agents

from pyrua import get_desktop_ua, get_mobile_ua, get_android_ua, get_ios_ua

# Desktop User-Agent (random browser/OS)
desktop_ua = get_desktop_ua()

# Mobile User-Agent (Android or iOS)
mobile_ua = get_mobile_ua()

# Android-specific
android_ua = get_android_ua()

# iOS-specific (iPhone/iPad)
ios_ua = get_ios_ua()

Advanced Customization

from pyrua import get_ua, Browser, OS, DeviceType

# Chrome on Windows
ua = get_ua(browser=Browser.CHROME, os_type=OS.WINDOWS)

# Firefox on macOS
ua = get_ua(browser=Browser.FIREFOX, os_type=OS.MACOS)

# Any mobile User-Agent
ua = get_ua(device_type=DeviceType.MOBILE)

# Safari on iOS
ua = get_ua(browser=Browser.SAFARI, os_type=OS.IOS)

# Chrome on Android
ua = get_ua(browser=Browser.CHROME, os_type=OS.ANDROID)

Bulk Generation

from pyrua import get_rua_list

# Generate 10 unique random User-Agents
ua_list = get_rua_list(count=10, unique=True)

for ua in ua_list:
    print(ua)

Realistic Distribution

from pyrua import get_common_ua

# Generate User-Agent based on real-world browser market share
# (Chrome ~65%, Safari ~18%, Edge ~5%, Firefox ~3%, etc.)
common_ua = get_common_ua()

🛠️ Use Cases

Web Scraping with Requests

import requests
from pyrua import get_rua

headers = {
    'User-Agent': get_rua()
}

response = requests.get('https://example.com', headers=headers)

Selenium WebDriver

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from pyrua import get_chrome_ua

options = Options()
options.add_argument(f'user-agent={get_chrome_ua()}')

driver = webdriver.Chrome(options=options)

aiohttp Async Requests

import aiohttp
from pyrua import get_rua

async def fetch(url):
    async with aiohttp.ClientSession() as session:
        headers = {'User-Agent': get_rua()}
        async with session.get(url, headers=headers) as response:
            return await response.text()

httpx Client

import httpx
from pyrua import get_rua

client = httpx.Client(headers={'User-Agent': get_rua()})
response = client.get('https://example.com')

Rotating User-Agents

from pyrua import get_rua_list

# Pre-generate a pool of User-Agents
ua_pool = get_rua_list(count=100, unique=True)

# Use in rotation
import itertools
ua_cycle = itertools.cycle(ua_pool)

for url in urls:
    headers = {'User-Agent': next(ua_cycle)}
    # ... make request
