Check and test a proxy endpoint for connectivity, response time, anonymity level, and the exit IP it presents to target servers.
Enter your proxy address in host:port format (e.g., proxy.example.com:8080).
Optionally add username and password for authenticated proxies.
Click "Test Proxy" and review the connectivity, speed, and anonymity results.
Proxy connectivity (TCP handshake success), response time in milliseconds, exit IP address and geolocation, anonymity level (transparent, anonymous, or elite), and forwarded header detection.
A misconfigured proxy can leak your real IP through X-Forwarded-For or Via headers, making it effectively useless. Testing before deployment catches configuration errors, identifies slow endpoints, and confirms the proxy exits in the expected geography.
The tool constructs an HTTP request through the provided proxy endpoint to a header-echo service. It measures round-trip time, parses the response for the visible IP, and checks for proxy-revealing headers (X-Forwarded-For, Via, X-Real-IP). Anonymity is classified based on which headers leak.
Transparent proxies forward your real IP in headers. Anonymous proxies hide your IP but reveal they are proxies via the Via header. Elite (high-anonymity) proxies hide both your IP and any evidence of proxy usage.
Proxy latency depends on the physical distance between you, the proxy server, and the target. Overloaded shared proxies also slow down. Residential proxies are typically slower than datacenter due to last-mile ISP routing.
The proxy server rejected your connection. Common causes: wrong port number, the proxy is down, your IP is not on the allowlist, or a firewall is blocking the connection. Double-check your proxy credentials and endpoint.
Run this check again from a clean all proxy types exit and see what actually reaches the other side.
