Proxy Checker

We open a real TCP connection through each proxy and measure reachability. Supports host:port and host:port:user:pass entries.

Probes run from our server. We never store your proxies - results stay in this browser session.

How it works

Stop trusting proxy lists at face value

Latency, anonymity, geo, ASN and header leaks decide whether a proxy is actually usable. Check the basics in one probe.

Step 1

Paste your list

Drop up to 25 host:port entries - HTTP, HTTPS or SOCKS5. One per line or comma-separated.

Step 2

Real parallel probes

We open a TCP connection to each proxy and measure connection time.

Step 3

Enriched results

You get reachable status, endpoint parsing and timing signals without saving the list.

Real latency, not ping

TCP connect timing is closer to what affects scraping throughput.

Anonymity verdict

Use the probe result as the first pass before deeper request-level testing.

Geo + ASN truth

Catch endpoints that claim one location but route through a different network.
