The Proxy Checker is a tool that allows users to check proxy servers and obtain all basic information about them. The tool is free, whether proxies are used for personal or commercial purposes.

The Proxy Checker will be useful for those who use proxy lists that include free proxies. It is also useful for those who need to check paid proxies with authentication.

With this tool, you can: Check a large number of proxies at once. Filter out unsuitable ones. Sort selected IP addresses by various parameters. This tool saves time when working with proxy lists and can also save money (you might find free proxies of suitable quality for your task).

Proxy Checker Features

The Proxy Checker offers the following features:

  • Work with proxy lists in different formats. Lists can be uploaded in json, csv, txt, and xls formats.
  • Export check results in various output formats. Final information can be output in json, csv, txt, or xls documents, and can have the format: IP:Port or IP:Port:Login:Password.
  • Reduce proxy check time. Achieved through multithreading. The free version of the proxy checker processes 20 threads simultaneously. If you want to increase this number (and, accordingly, the processing speed), you can purchase a paid subscription (NETWORK TOOLS), which supports 64 threads. This feature is available for our service clients for free.
  • Ability to perform checks with or without authentication. Check both IPv4 and IPv6 proxies.
  • Check up to 100 addresses per session. Our clients can check more than 100 addresses in a single session (authentication requires an access code). This feature is also available to those who purchase a paid subscription (NETWORK TOOLS).
  • Customize the display of check results. For example, you can exclude non-working proxies from the final list (you just need to tick the "Working" box in the results filter, in the "Status" selection).
  • API Availability. This allows the proxy checker to be integrated inside various third-party products (websites, programs, etc.). API access is available for users with a paid subscription (NETWORK TOOLS). For our clients, API access is free.
