A high-performance Python script that checks and validates proxy servers from a list, saving only the working ones. Perfect for:
- Web scraping projects
- Privacy protection
- Load testing
- Market research
- Multi-threaded checking (20 concurrent checks)
- Fast validation with 10-second timeout
- Simple setup - just provide a list of proxies
- Detailed output showing working proxies and their IPs
- Lightweight with minimal dependencies
- Ensure you have Python 3.6+ installed
- Install dependencies:
pip install requests
🚀 Usage
Basic Usage
1. Create proxies.txt file with your proxies (one per line):
1.1.1.1:8080
2.2.2.2:3128
3.3.3.3:8888
2. Run the script:
python proxy_checker.py
3.Working proxies will be saved to working_proxies.txt
Advanced Options
Modify these variables in the script:
max_workers: Change thread count (default: 20)
timeout: Adjust timeout in seconds (default: 10)
test_url: Change verification endpoint (default: httpbin.org)
