Proxy checker
Test up to 20 proxies at once: alive or dead, HTTP, SOCKS4 or SOCKS5, latency, country, and whether the proxy hides your IP. Free, no signup.
Proxy checker questions
How do I check if a proxy is working?
Paste it above as ip:port, one per line, up to 20 at a time, and press Check. Each proxy gets one request to our test endpoint. A proxy that answers within 6 seconds is marked alive, with its latency; one that doesn't is marked dead.
Which proxy types can it test?
HTTP, SOCKS5 and SOCKS4. Write the protocol in front (socks5://1.2.3.4:1080) to test just that one; a bare ip:port is tried as HTTP, then SOCKS5, then SOCKS4, and the result shows which one answered.
What does the anonymity result mean?
We compare what our endpoint saw through the proxy with a direct request. Transparent means the proxy passed your real IP along. Anonymous hides your IP but announces that a proxy is in use. Elite hides both.
Can it check proxies with a username and password?
No. The checker only takes public IPv4 addresses without a login, and lines with user:pass are listed as skipped. To test a paid proxy, run curl -x through it, or use the Test connection button in your provider's dashboard.
Why does a proxy that worked earlier show as dead?
Free proxies come and go within hours, and many refuse requests from some networks. A dead result means it didn't answer our test from our server just now; it may still answer from yours. Our free list re-checks every proxy every 30 minutes for the same reason.
Need proxies that stay up?
Grab working ones from the free proxy list, re-checked every 30 minutes, or use residential, datacenter and mobile IPs billed per GB. Bandwidth never expires.
