CheckerProxy is a free online proxy checker at checkerproxy.net, and the same site now also answers at checker.net. It sells no proxies. What sets it apart is a public archive: the addresses people check go into a daily list anyone can download, unless they opt out.
We read its pages, its robots.txt and its archive on October 23, 2026. We then checked one full day of the archive once, with our own checker, and report counts only. We did not run CheckerProxy's own checker.
What does CheckerProxy offer?
A checker in the browser. You paste a list or upload a file, and it tests each proxy over HTTP, HTTPS and SOCKS5. Its fast mode only confirms that an address answers. Its full mode also tests the proxy against 11 platforms, from Google and YouTube to TikTok, and rates it from 0 to 5. The rating adds a point for a mobile address and half a point for a residential one. It also looks each address up on blacklists and grades its anonymity as transparent, anonymous or elite. The default timeout is 10 seconds.
An API runs on checker.net. It takes up to 30,000 proxies in one check, with a key from an account. The domain checkerproxy.net dates from 2011 and checker.net from 2019, by their registry records.
Where does its archive come from?
From the checks people run. The checker's form carries a box marked "Do not save my proxies to the public list". Its own instructions tell anyone checking purchased private proxies to tick it, and say why: "then they will not end up in the open archive".
So a proxy checked without that box ticked can end up in a public list, with its address and port. If you check proxies you paid for, tick it every time.
Its API lists the last 30 days of the archive with a count for each, and returns any day's addresses in full. Between September 23 and October 22, 2026, a day held a median of 22,433 addresses:
How many of the archived proxies worked?
We took the list as published for October 22, the last full day: 15,371 lines on 5,896 IP addresses. One block of 256 addresses held 8,825 of those lines, 57.4 percent of the day, on many different ports.
We sent all 15,371 lines through our own checker once, on October 23, 2026, between 12:38 and 12:47 UTC, from our checker's servers. Lines our checker ran out of time on had a second pass. It still could not finish 1,813 of them, and those carry no verdict, so the shares below count the 13,558 lines it finished:
The big block pulled the rate down. Of its 8,825 lines, our checker finished 7,029, and 558 of those worked, 7.9 percent; it ran out of time on 1,796. The day's other lines worked at 29.5 percent of the 6,529 it finished. Of all the proxies that worked, 1,801 graded elite, 370 anonymous and 312 transparent, which forward your own address. Their median response time was 4.8 seconds.
For comparison, our audit of public lists on September 9, 2026, found 163 of 961 sampled entries relaying a request, which is 17.0 percent.
A free checker that keeps your proxies private
We make a free proxy checker, and we sell residential proxies, so read this part with that in mind. Our online proxy checker needs no account and takes up to 100,000 lines a run. It tries HTTP, HTTPS, SOCKS4 and SOCKS5 on every line and reports the anonymity grade, location and network of each exit. What you paste never joins our free list.
For a proxy locked to your own IP address, our free app on the proxy checker page runs the same check from your connection.
If you want a free list rather than a checker, our free proxy list is checked around the clock by the same checker. We have looked at other free sources the same way: Live Socks, monosans on GitHub, NNTime, PremProxy and Proxifly on GitHub.
Where HProxy fits
The checkers are free. What we sell is residential proxies: Residential Lite costs $0.50/GB for one GB, falling to $0.18/GB at 1,000 GB+, and the balance does not expire. If free lists keep failing your checks, a paid pool is the next step, and you can test it with the same tools.
What we could not find out
We did not run CheckerProxy's own checker, so we cannot say how it rates the same lines. Our check ran once, from our checker's servers, a day after the archive collected the lines, and free proxies come and go within hours. The archive's page says what goes into it, but not whose proxies those are.
