Proxy Checker

Test a list of HTTP and SOCKS proxies.

Find out which proxies in your list still work, and how fast they are.

Paste a list of proxies. Hit start. Proxy Checker walks every entry, attempts to reach a known test target through it, and reports each proxy as live or dead along with the response time.

What it does

Supports HTTP, HTTPS, and SOCKS4/5 proxies. The list format is one proxy per line in host:port form. The tool tests each one against a configurable validation URL and classifies the result: working, timeout, refused, or wrong-content (the URL returned but the response wasn't what the test expected, suggesting a captive portal or interceptor).
