Batch proxy checker

Proxy lists rot. Providers rotate ranges, free lists fill with dead servers, and the pool you set up last month quietly loses a few proxies every week. Checking them one at a time is miserable, so this page takes the whole list at once.

Paste up to 100 proxies, one per line, and hit check. The tool runs several tests in parallel and fills in results as they land. Every line gets one real request through the proxy, the same test the single proxy checker runs, so a green result here means the proxy actually moved traffic, not just that the port was open.

1. 01Paste your list, one proxy per line. Mixed lists are fine: lines that name their own protocol, like socks5://host:port, keep it, and every other line uses the dropdown.
2. 02Leave the protocol on Auto unless you know better. Auto tries HTTP, SOCKS5 and SOCKS4 against each proxy and records whichever one answered.
3. 03Hit check and watch the report fill in. When the run finishes, one click copies all the live proxies, ready to paste into whatever you are building.

Duplicate lines are removed automatically, so you can paste straight from a messy file without cleaning it up first.

Each row shows the proxy you entered, the protocol that worked, the exit IP, and the response time. Failed rows show the exact error instead, and the counter at the top keeps a running tally of live and dead.

Two things to keep in mind before you delete the failures. First, a proxy that fails here but works on your machine usually means IP allowlisting: your provider accepts connections from your registered IP and refuses our test server. Second, overloaded proxies sometimes time out on the first attempt and pass on the second, so a retest of the failures is worth ten seconds before you throw them away. The full decoder for every error message is in common proxy errors and how to fix them.

The obvious moment is right after buying: run the fresh list through, confirm the advertised countries match the report, and open a support ticket while the purchase is still new if half of them are dead. The less obvious moment is before every serious scraping run. Pruning dead proxies from your pool up front costs a minute and saves you from debugging mystery failures in your own logs later.

One honest limit: this tool tells you a proxy works and where it exits. It cannot tell you whether your target website will accept that proxy, because working and welcome are different things. If your live proxies still get blocked somewhere, residential vs datacenter proxies explains what the site is seeing.
