Proxy Grabber And Checker Top

A great tool doesn't just check once; it re-verifies proxies on a schedule (e.g., every 30 minutes).

def check_proxy(proxy): try: r = requests.get('https://httpbin.org/ip', proxies='http': f'http://proxy', timeout=5) if r.status_code == 200: return proxy except: pass return None

Best for: Red teams and penetration testers.
Grabber: Scrapes 25+ sources every hour.
Checker: Auto-tests with customizable timeout and concurrency.
Top feature: Generates ready-to-use proxy lists for Nmap, Burp Suite, and SQLMap.
Limitation: Command-line only; occasional broken scrapers due to source changes. proxy grabber and checker top

The best checkers use asynchronous I/O or multi-threading. For example, checking 10,000 proxies in 10 seconds is the mark of a top performer.

A top checker must use multithreading. Below is an optimized version using concurrent.futures. A great tool doesn't just check once; it

import concurrent.futures
import requests
def check_proxy(proxy):
try:
response = requests.get('https://httpbin.org/ip',
proxies='http': f'http://proxy',
'https': f'http://proxy',
timeout=5)
if response.status_code == 200:
return proxy, response.elapsed.total_seconds()
except:
pass
return None, None
def main():
raw_proxies = grab_proxies()
working_proxies = []
with concurrent.futures.ThreadPoolExecutor(max_workers=200) as executor:
results = executor.map(check_proxy, raw_proxies)
for proxy, latency in results:
if proxy:
working_proxies.append((proxy, latency))
# Sort by latency (fastest first)
working_proxies.sort(key=lambda x: x[1])
return working_proxies
