Free proxy checker.

Paste any proxy IP, IP:port, or full proxy URL. We'll return its country, ASN, ISP, and network type — plus a copy-paste cURL command you can run to verify the proxy actually works and to see which headers it forwards.

Check a proxy

Accepts any of: 1.2.3.4, 1.2.3.4:8080, user:[email protected]:8080, or http://... / socks5://....

We can't connect through the proxy from here, but you can run this command in your terminal to verify it actually works:

# paste a proxy first

We don't store any proxies you check. Each lookup hits public IP intelligence APIs from your edge worker session and returns the result. The cURL command is generated client-side — you run it in your own terminal where the actual connection is tested.
