ProxySpider can scrape thousands of proxies from all over the internet, and it can continue scraping fresh proxies while you work.
When ProxySpider scrapes proxies, it checks them at the same time and categorizes them by country, speed, anonymous proxy, highly anonymous proxy, gateway, referer, cookie, https, post, delay, etc. It supports http, socket4, socket5, etc. You can also import a local file to check and categorise proxies listed in the file.
After checking proxies, you can filter them based on the category and export into a file, or output them to other programs in real time.
