ProxyChecker is a high-performance Go-based proxy checker that supports SOCKS4, SOCKS5, and HTTP proxies. It fetches, sanitizes, and tests proxies against a given target, allowing users to efficiently verify working proxies.

With the ability to scrape approximately 350,000 proxies per type, ProxyChecker ensures a vast selection of proxies to work with.

• Supports SOCKS4, SOCKS5, and HTTP proxy types
• Fetches proxies from URLs in a JSON file (urls.json)
• Concurrency support with configurable worker limits
• Progress tracking and logging
• Saves working proxies in categorized files
• Graceful cancellation support using context
• Silly cat when running ^^

Ensure you have Go 1.18+ installed.

git clone https://github.com/lilsheepyy/proxy-scrapper-checker
cd proxy-scrapper-checker
go run main.go

• -max-checks → Maximum concurrent proxy checks (default: 1000) I recommend lowering this for a better output even if it takes more time, this also depends on your server
• -target → IP and port to test proxies against (default: 1.1.1.1:80)
• -timeout → Timeout in seconds for proxy connections

go run main.go -target 1.1.1.1:80 -max-checks 1000 -timeout 5

IF YOU ARE GETTING 5 PROXIES WORKING, LOWER YOUR SETTINGS

THIS ONLY CHECKS IF THE PROXY CAN PERFORM TCP RAW CONNECTIONS (im working on checking traffic thru it)

• Make a better sanitization system
• Anything else that I think off

Thanks for using!
