Proxy Checker
Check a whole list at once. Quick mode tells you which proxies work, how fast they are and where they exit. Full mode also tests them on the sites you pick, checks anonymity and whether the IP sticks or rotates.
Works or not, speed, exit IP, location and blacklists.
Any common format works: with or without a login, http, https or socks5 in front, fields split by colons, spaces or commas.
What each mode checks
Quick for sorting a big list, full for knowing exactly how good each proxy is.
Paste up to 100 proxies in any format. HTTP, HTTPS and SOCKS5 are found by themselves, and duplicates are removed.
With the exact reason when it fails: wrong password, timeout, refused, no answer.
Connecting, the proxy login, TLS, the first byte and the download, plus a second request on the same connection.
The IP websites really see: residential, ISP, mobile or datacenter, its country, city and network, and whether it's on a public blocklist.
Up to 15 from 35 big sites like Google, Instagram, TikTok, YouTube, PayPal and Stripe, plus up to 3 of your own. A site passes only if the real page loads, not a captcha.
Whether the proxy adds headers that tell sites it's a proxy, or leaks your real IP.
Three fresh connections show if the IP stays the same or changes. Most checkers skip this.
Real UDP traffic through SOCKS5 proxies, the kind games, calls and HTTP/3 need, and the IP that UDP leaves from.
The p0f network fingerprint shows if the proxy exits from Windows, Linux or Android, or an Apple device.
One grade from speed, site results, blacklists and anonymity, so you can sort a big list fast.
