Online Proxy Validation Tool

Proxy checker is a service that allows you to verify the availability of proxy servers and determine their type and geolocation. Get results without downloading any software.

What format should proxies be added in?
If you have public proxies (no login and password): IP:PORT
If you have private proxies (with login and password): USER:PASS@IP:PORT
P.S.: If you have new proxies, they are private!

How Does the Proxy Checker Work?

The checking process is performed server-side: we attempt to establish a real connection through each proxy to an external test endpoint and measure the response time. This approach gives accurate results regardless of your local network and works for both public and private (authenticated) proxies.

For each proxy from your list, the checker automatically detects the protocol type – HTTP, SOCKS4 or SOCKS5 – and reports the country of origin based on the proxy's IP address.

How to Use the Proxy Checker?

Paste your proxy list into the text field, one proxy per line. Supported input formats:

  • IP:PORT – for public proxies without authentication
  • USER:PASS@IP:PORT – for private proxies with login and password

Click Start checking and results will appear in real time as each proxy is tested. You can filter the results to show only working HTTP, SOCKS4, SOCKS5 proxies, or include non-working ones as well.

Why Check Your Proxies?

Proxy servers can become unavailable at any time. Regular checking helps you maintain a working proxy pool, avoid connection errors, and ensure the anonymity and reliability you depend on. Our tool processes up to 50 proxies per request with concurrent checks, so you get results quickly.
