Automatic detection
HTTP, SOCKS5 and SOCKS4 are tested automatically. No protocol selection needed.
Advanced settings
The judge is the page fetched through every proxy to read its exit IP and leaked headers. “This server” works when MRAIT Proxy Checker is publicly reachable (deployed) or when testing proxies on your own network; use a public judge for public proxies from a local install.
Your list is never saved to disk.
Temporary results expire after 30 minutes. No account. No saved history.

Results
Some proxies could not be verified.
Detection can fail when a proxy is offline, blocked or incompatible with the test destination. If you know its protocol, retry the failed entries below.
No results match the current filters.

Automatic protocol detection
Can’t tell HTTP from SOCKS5? MRAIT Proxy Checker tries HTTP, SOCKS5 and SOCKS4 in order and reports what each proxy really speaks.
Real anonymity levels
A judge page shows what each proxy leaks: elite (no proxy headers), anonymous (proxy headers, IP replaced) or transparent (your real IP visible).
Verified HTTPS support
Not just a CONNECT probe: we complete a genuine TLS handshake through the tunnel, so the HTTPS column can be trusted.
How to check proxies in 3 steps
Paste or upload your proxy list
Any mix of ip:port, user:pass@ip:port, ip:port:user:pass or protocol://ip:port — one per line. Extra text, comments and duplicates are handled for you, or load a list straight from a URL.
Check proxies
HTTP, SOCKS5 and SOCKS4 are tested automatically. No protocol selection needed.
Watch live results & export
Working proxies stream in with latency, anonymity, country and ISP. Filter, sort, then export TXT / CSV / JSON or copy the working list.
Frequently asked questions
How do I check if a proxy works?
Paste the proxy into the checker (ip:port is enough) and press “Check proxies”. A “working” status means MRAIT Proxy Checker connected through the proxy, fetched the judge page and got a valid answer — the same test a browser or scraper would perform.
What do elite, anonymous and transparent mean?
They describe what the proxy leaks. Transparent proxies forward your real IP (in headers like X-Forwarded-For) — useless for privacy. Anonymous proxies hide your IP but still announce they are a proxy via headers like Via. Elite (high-anonymity) proxies hide your IP and send no proxy headers at all — the best for scraping and privacy.
How many proxies can I check for free?
Free and without registration: paste thousands of proxies, run up to 50 parallel threads, and watch results stream in live.
Why do results differ from other checkers or my own machine?
Checks run from the server MRAIT Proxy Checker is installed on, so network path, judge choice and timeout all influence results. A proxy can be alive from one vantage point and dead from another. Raise the timeout or switch the judge to compare fairly.
Is my proxy list stored or shared?
Lists and results stay temporarily in server memory and expire after 30 minutes. We do not save proxy lists to disk or reuse them. Checking sends test requests through your proxies to the selected judge and TLS/target hosts. When location lookup is enabled, exit IPs are sent to ip-api Pro over HTTPS; proxy credentials are not sent to that provider. An IP-based request counter is used for abuse protection.
What is the difference between HTTP, HTTPS and SOCKS proxies?
HTTP proxies forward plain web traffic. “HTTPS” (CONNECT-capable) proxies can also tunnel encrypted TLS traffic — we verify this with a real handshake. SOCKS4/SOCKS5 are lower-level: they tunnel any TCP traffic, with SOCKS5 adding auth and IPv6/UDP support. Auto-detect tries all of them and labels what each proxy actually speaks.
