Free proxies work in GoLogin for one job: a throwaway test profile that proves your proxy settings work. For a profile that holds an account, they are the wrong tool, and GoLogin says why itself. Its help centre puts free proxies in the same group as shared proxies, "used by multiple users at the same time", with a "higher risk of blacklisting". Our tests of free proxies from our list agree. On 28 September 2026, more than one in four working free proxies on ordinary addresses in our pool were labelled datacenter, 82.9 percent counting every entry, and about one in four working web proxies there was transparent.
This page covers what GoLogin says, what our tests showed, and how to check a proxy before a profile touches it.
What GoLogin says about free proxies
GoLogin also sells proxies, so we quote its help centre without linking it.
- Shared or free. In "Private vs Shared" (3 April 2026), GoLogin files free proxies under shared ones: "Shared proxies are used by multiple users at the same time". It lists "slower performance" and a "higher risk of blacklisting". It adds: "There's a chance of using the same proxy on the same website with another proxy user, keep that in mind for account management".
- Checking. When you add a proxy, "Gologin will check your proxy right away". A green indicator means it works, and a red one means it does not.
- Protocols. GoLogin says SOCKS5 "supports both TCP and UDP connections". The protocol does, through a mode RFC 1928 calls UDP ASSOCIATE. Free SOCKS5 proxies rarely offer it, as our test below shows.
What our tests showed
Every test ran from our server on working entries of our free pool, on addresses that held fewer than 20 of them.
- Networks. On 28 September 2026, 1,319 of the 4,751 working free proxies on ordinary addresses in our pool were labelled datacenter. Counting every entry, 82.9 percent were. The label is the public network type of each address.
- Privacy. On the same day, 925 of 3,870 working free web proxies on ordinary addresses were transparent, 23.9 percent, and 5.1 percent counting every entry. They pass your own address on.
- Downloads. In two runs against our own website, 104 and 116 of 200 working free proxies on ordinary addresses sent no data within 30 seconds. Only 65 and 49 delivered the same 3.3 MB file, whole or still arriving.
- UDP. Of 425 working free SOCKS5 proxies on ordinary addresses, 22 carried a UDP packet, about 1 in 20.
- Lifespan. Those that worked and then stopped lasted a median 10 days, counting only addresses with fewer than 20 of them, without Amazon's networks or one June evening when our checker failed (measured 2026-09-28).
The one job a free proxy fits in GoLogin
A test profile that holds no account. Add the proxy, watch the indicator GoLogin shows, open a public page and throw the profile away. Never log in to anything through it. Many platforms forbid extra accounts in their terms, whatever the browser, and this page gives no steps for running several accounts.
Your accounts are worth protecting
A proxy is a server run by a stranger, in the middle of your traffic, and it adds no encryption of its own. On a clean HTTPS connection your password is encrypted in transit. A hostile proxy can still present a fake certificate and hope you click past the warning. In our test on 28 September 2026, 161 of the 268 free SOCKS5 proxies on ordinary addresses that finished a TLS handshake with our own site handed back a certificate that was not ours. A 2018 study of more than 107,000 listed open proxies found TLS man-in-the-middle attacks. Our guide to whether free proxies are safe covers the rest.
Where a free proxy fits in GoLogin, and where it does not
| What you want to do | Free proxy? | Why |
|---|---|---|
| Test your proxy settings on a throwaway profile | Sometimes | GoLogin checks the proxy when you add it, and many free ones fail. |
| Hold an account in a profile | No | GoLogin warns that shared proxies carry a higher risk of blacklisting. |
| Run several accounts | No | This page gives no steps. Many platforms forbid extra accounts. |
| Carry UDP traffic | No | About 1 in 20 free SOCKS5 proxies did. |
| Log in or pay | No | A hostile proxy can try to read your login. |
Test any proxy before a profile uses it
A free proxy that worked ten minutes ago may already be gone. Paste any candidate into our free proxy checker, with no signup. It makes a real connection through the proxy and reports the exit address, country, latency and anonymity grade. From the command line, the same check is one request to our free checker API.
# Tests one proxy from our server: alive or dead, protocols, anonymity, latency, country
curl "https://hproxy.com/api/proxy-check?proxy=203.0.113.7:1080"
The anonymity grade matters here, since a transparent proxy passes your own address on. The full method is in how to check if a proxy is working.
When free is not enough
For web tasks that have to keep running, such as checking your own site from another country, a residential proxy is the better tool. Its address belongs to a home connection, and it stays up while you work. Ours start at $0.44/GB, pay as you go, and purchased traffic has no scheduled expiry date. No proxy of any kind makes extra accounts allowed where a platform forbids them.
The plain answer
Free proxies in GoLogin are for a throwaway test profile only. GoLogin files them with shared proxies and warns of a higher risk of blacklisting. In our tests on ordinary addresses, 28 percent were labelled datacenter, 24 percent of web proxies passed your own address on, over half sent no data from our own website within 30 seconds, and about 1 in 20 SOCKS5 proxies carried UDP. Never sign in through one. For web tasks that can fail, start with our free proxy list.
How we measured
All tests ran from our server in the United States on working entries of our free pool, on 28 September 2026. Each figure counts addresses that held fewer than 20 working entries, and the figure over every entry stands next to it where it moves a lot. The datacenter labels and the transparent share come from one read-only query at 18:28 UTC. The download test asked 200 working free proxies from such addresses for the same 3.3 MB file from our own website, twice. All had passed our HTTPS check, each had 30 seconds, and the runs finished at 22:29 and 23:17 UTC. The certificate test made one TLS handshake with our own site through every free SOCKS5 proxy on such an address, from 18:28 to 18:35 UTC. The UDP figure comes from our census of every working SOCKS5 entry on an ordinary address at 16:04 UTC. We read the GoLogin help centre from our server on 28 September 2026, in English. We sent no free proxy to GoLogin. We store no proxy addresses from these tests, and every time is in UTC.
