How do I test proxies online?
Paste your proxies into the box, one per line, choose a target and a proxy type, and press Test proxies. Each proxy loads the target from our test server in Ohio, US. The table shows whether it worked, its exit IP, location and network, the target's status code and the latency.
How many proxies can the proxy tester check at once?
Up to 500 a run, or 5,000 when you are signed in. The list goes to the test server 50 lines at a time, so results fill in while the rest are checked, and you can stop a run at any point. In a day you can test 2,000, or 20,000 signed in.
What does the proxy checker show?
For each proxy: whether it works, with the reason in plain words when it failed; the exit IP; the protocol it answered in; the target's status code; the latency; and the location and network of the exit IP. With Google, Wikipedia or your own URL as the target, the exit IP comes from a second request to our IP check, so a rotating proxy shows the address it used for that request. Locations are looked up on our own server: IP geolocation by DB-IP.
Can I test SOCKS5 proxies?
Yes. Choose SOCKS5, or leave the type on Auto and the Type column shows whether each proxy answered in HTTP or SOCKS5. Lines that start with
socks5:// are always tested as SOCKS5, and lines that start with http:// as HTTP.Can I test proxies against my own URL?
Signed-in users can choose Custom URL and enter any public
http or https address on its standard port, with no login in it. Each proxy line needs its own login for a custom URL. Everyone can test against the ResiFactory IP check, Google or Wikipedia.What formats can I paste into the proxy checker?
host:port, host:port:user:pass and user:pass@host:port, with or without http:// or socks5:// in front. Use the proxy formatter first if your list is in another shape.Why did my proxy fail the test?
Each failed line says why. The usual reasons: the proxy rejected the login, it did not answer in time, nothing is listening on that port, or the target refused the exit IP. Lines with a private address or a mail port are not tested.
Can I download or share the results?
Download writes a CSV file in your browser. Share results makes a read-only link that lasts 30 days. Both list hosts and ports, never a login or password.
Is the proxy tester free?
Yes. Signed out, one address can test up to 500 proxies in 10 minutes and 2,000 a day. Signed in, you can test up to 5,000 in 10 minutes and 20,000 a day.
What happens to the proxies I paste?
Your browser sends them to our server over HTTPS. The server uses each login for that one test and does not log, store or return it. Results, downloads and shared links hold no login.
Need the list in another format?
The proxy formatter converts it in your browser.
