Online proxy checker
Find out in seconds whether a proxy works: HTTP, HTTPS or SOCKS5, the exit IP, ping and anonymity level. Up to 20 proxies at once, including ones with a username and password.
What the proxy checker tests
Is it alive
We connect to the proxy and make sure a site loads through it.
Protocol
HTTP, HTTPS (CONNECT) or SOCKS5 — detected automatically.
IP and ping
The exit IP websites see and the response time in milliseconds.
Anonymity
Whether the proxy reveals itself or your real IP in headers.
Proxy anonymity test
An HTTP proxy may add headers such as Via or X-Forwarded-For. They tell a website that you came through a proxy and sometimes reveal your real IP. SOCKS5 and HTTPS (CONNECT) are tunnels: the proxy does not touch the headers, so such proxies are always elite.
The site sees neither the proxy nor your IP.
The site sees a proxy, but your IP is hidden.
The site sees your real IP — not suitable for account work.
How to check a proxy with a username and password
Paste proxies the way your shop gave them: user:pass@host:port or host:port:user:pass. Credentials are only used to connect to the proxy and are never returned in the response.
Checking SOCKS5 works the same way: just paste the line, or prefix it with socks5:// to test SOCKS5 only.
FAQ
Do you store my proxies?
No. The list is only used for the check: we don’t store it, log it or share it with anyone. There are no analytics or trackers on this page.
How many proxies can I check?
Up to 20 at a time. The checker is free, so there is a daily limit per IP address — enough for regular use.
Why does a proxy “not work” here but works in my app?
We check from our own server. If the proxy is bound to your IP (whitelist) or the provider blocks third-party connections, the checker cannot reach it. Another reason is a slow answer: each attempt gets about 10 seconds.
Which protocols are supported?
HTTP, HTTPS (CONNECT) and SOCKS5, with or without username and password. SOCKS4 is not supported yet.
Do you show the proxy country?
Not yet — for now the checker shows the exit IP, type, ping and anonymity. Country lookup is coming later.
