Live or dead
A real request through every line
Each proxy opens an actual connection rather than answering a ping, so live means it carried traffic and dead means it did not.

Paste a list, press Check. Every format parsed as you type, then a real request through each line — live or dead, in milliseconds.

Paste a list above and it is parsed as you type.
Checked lines are used once and never stored.
Get proxies that passHow it works
From a pasted list to a verdict
Parsed as you type, checked with a real connection, read back line by line.
Formats
Four formats, one parser
host:port, host:port:user:pass, user:pass@host:port and scheme:// prefixes, mixed together in the same paste, from any provider.

Exit IP, country and latency
Every live line comes back with where it exits and how fast it answered, so the list can be sorted before you build on it.

Everything in the checker
01Any providerNothing here is tied to our network. Bring a list from anywhere — it is the same parse either way.
02Four formats, one parserhost:port, host:port:user:pass, user:pass@host:port and scheme:// prefixes, mixed together in the same paste.
03The reason, not just a crossA rejected line says what is wrong with it — the port, the host, the credentials — rather than failing silently and leaving you to guess.
04Private addresses caughtLoopback, RFC-1918 and link-local get flagged. A list full of those usually means an export from a local config nobody else can reach.
05Duplicates droppedThe same host and port twice is one entry in the clean list, however differently the two lines were written.
06Latency and exit IPThe two things a parse cannot know: how long the round trip took through that proxy, and the address it actually came out of.
FAQ
Straight answers
Can't find the answer? A real person is on chat around the clock, or find us here:
That the request did not complete through that proxy — refused, reset, timed out, or the proxy rejected the credentials; the row says which. It does not always mean the proxy is dead: one can be alive and still be blocked by the endpoint we test against.
Yes, and there is no account behind it. It is useful to us as a tool people find us through, so it stays open.
No. Parsing happens in your browser and never touches us at all. Pressing Check does send those lines to our server, because a browser cannot make a request through a proxy — but they are used for one request each and dropped. Nothing is logged or kept.
The usable lines only, deduplicated, written as scheme://host:port. Paste that straight into whatever you were configuring.
