Proxy Checker
We open a real TCP connection through each proxy and route a live HTTP request through it — measuring latency, detecting the protocol, resolving the exit IP and enriching it with ASN, geo and anonymity data. Supports HTTP, HTTPS and SOCKS5 in the format host:port or host:port:user:pass.
Probes run from our server. We never store your proxies — results stay only in this browser session.
Stop trusting proxy lists at face value
Latency, anonymity, geo, ASN and header leaks — the five things that decide whether a proxy is actually usable. Check them all in one real probe.
Paste your list
Drop up to 25 host:port entries — HTTP, HTTPS or SOCKS5. One per line or comma-separated.
Real parallel probes
We open a TCP connection and route an HTTP request through each proxy, measuring connect + first byte.
Enriched results
Exit IP is resolved to ASN, ISP, country, region, city and reverse DNS — with anonymity verdict and leak list.
Real latency, not ping
TCP connect + end-to-end HTTP timing — the number that actually predicts your scrape throughput.
Anonymity verdict
Elite, Anonymous or Transparent — derived from the headers the proxy actually leaks to the target.
Geo + ASN truth
Catches IPs that claim US but route through a known datacenter ASN in another country.
