A free SOCKS5 proxy list is a set of public SOCKS5 endpoints, each one an IP address, a port, and the SOCKS5 protocol, that anyone can route traffic through without paying. Our free SOCKS5 proxy list sits at /free-proxy-list/socks5, gets re-checked every few minutes, and shows only the entries that answered on their most recent test, drawn from a pool that spans 100+ countries. This page explains what you are actually getting, when SOCKS5 beats an HTTP proxy, how to route traffic through one of these proxies, and how to tell in ten seconds whether the one you grabbed is alive or already dead.
The short version up front, because we run this network and would rather you not waste an afternoon: a free SOCKS5 list is a real tool for testing and low-stakes tasks, and a bad fit for anything with a login or a payment attached. The rest of this is the why, and the how.
What a SOCKS5 proxy actually is
A SOCKS5 proxy is a relay that forwards raw network connections without reading or changing what passes through them. It carries any TCP traffic (not just web requests), can resolve DNS on your behalf, and can relay UDP in some setups. It hides your IP from the destination, and it adds no encryption of its own, so it protects your identity but not your data. If your connection is already HTTPS, TLS keeps it private through the proxy; if it is plain HTTP, the proxy operator can read every byte.
That "does not read your traffic" property is the whole personality of SOCKS5. An HTTP proxy understands HTTP: it can parse your request, rewrite headers, cache responses, and block URLs. A SOCKS5 proxy only knows "connect me to this host on this port," then shovels bytes in both directions. Most free SOCKS5 proxies listen on port 1080, and you address them with the socks5:// or socks5h:// scheme depending on who does the DNS lookup (more on that below). If you want the protocol in full, including the handshake and the UDP asterisk, we wrote a plain-English breakdown of what a SOCKS5 proxy is.
When to pick SOCKS5 over HTTP
Reach for SOCKS5 when the traffic is not ordinary web browsing, or when you want the proxy completely out of your data stream. Reach for HTTP when your tool only speaks HTTP proxies, or when you specifically want the proxy to touch your requests (caching, header injection, filtering in a scraping pipeline). Neither is "more anonymous" by default, and neither encrypts anything. The choice is about what you are moving, not about safety.
Here is the quick decision, by task:
| What you're doing | Best free protocol | Why |
|---|---|---|
| Quick page or geo check in a browser | HTTP or SOCKS5 | Both carry web traffic; use whichever your tool accepts |
| Torrent client, game launcher, IRC, mail client | SOCKS5 | Native SOCKS support, carries non-HTTP TCP |
| Keeping DNS lookups off your local network | SOCKS5 (socks5h) | The proxy resolves the hostname, not your machine |
| Scraping that rewrites headers or caches responses | HTTP | Only HTTP proxies read and change requests |
| SSH hop, database, or custom TCP protocol | SOCKS5 | Carries arbitrary TCP an HTTP proxy cannot |
| Anything with a login, payment, or bot defense | Neither, use paid residential | Free datacenter IPs are pre-flagged everywhere |
For scraping specifically, the honest answer is "it depends on your framework," and we laid out the full head-to-head, tool by tool, in HTTP vs SOCKS5 proxy. If your scraper speaks both, SOCKS5 is a fine default because it stays out of the way; if it leans on header rewriting or response caching, HTTP earns its place.
One thing to state plainly: the transparent, anonymous, and elite grades you see on proxy lists describe headers that an HTTP proxy inserts. SOCKS5 never touches that layer, so those grades do not map onto it the same way. A SOCKS5 proxy cannot leak your IP in an X-Forwarded-For header because it never writes headers at all. That is a structural property, not a setting, and it is one of the few real privacy advantages the protocol has.
How to use a SOCKS5 proxy from the list
Grab an entry from the list (say 198.51.100.14:1080) and route a request through it with curl. The only new thing versus an HTTP proxy is the scheme:
# DNS resolved on your machine, then connect
curl -x socks5://198.51.100.14:1080 --max-time 10 https://httpbin.org/ip
# DNS resolved at the proxy (usually what you want)
curl -x socks5h://198.51.100.14:1080 --max-time 10 https://httpbin.org/ip
If the reply shows the proxy's IP instead of yours, the relay works. The difference between the two schemes matters more than it looks. With plain socks5://, your own machine resolves the hostname first, which leaks your DNS queries to your local resolver even though your traffic exits elsewhere. With socks5h://, the proxy does the lookup, so both the connection and the DNS query leave through the proxy. If you are using a proxy for privacy, use the h form.
Most applications that support SOCKS5 take the same three fields: host, port, and (for browsers and torrent clients) a checkbox to resolve DNS remotely. In Firefox that is the "Proxy DNS when using SOCKS v5" option, which is the GUI version of socks5h. If you would rather pull live endpoints straight into a script, our free proxy API serves the SOCKS5 slice on its own:
# One live SOCKS5 proxy, checked recently
curl "https://hproxy.com/api/proxy-list?format=txt&protocol=socks5&recent=true&limit=1"
Verify every proxy before you trust it
This is the step people skip and then blame the list for. Free proxies die fast, so a proxy that was alive when the page loaded can be dead by the time you paste it. Test it right before you use it, not when you first saw it. The one-line check:
curl -x socks5h://198.51.100.14:1080 --max-time 10 https://httpbin.org/ip
Keep --max-time in there so a dead proxy fails in ten seconds instead of hanging. If it times out or errors, throw it away and grab the next one. If you would rather not run a command per proxy, paste the IP and port into our free proxy checker and it reports the exit IP, country, and latency in one pass, and confirms whether the endpoint really is SOCKS5. For the full method (liveness, speed, exit country, and the header check that only applies to HTTP proxies), see how to check if a proxy is working.
Two SOCKS5-specific notes. First, the anonymity-grade check from that guide is an HTTP thing, so do not expect a SOCKS5 proxy to come back "elite" the same way; there are no forwarded headers to grade. Second, if you need UDP (some game and streaming setups do), test it separately, because a large share of real-world SOCKS5 servers, especially free ones, quietly disable UDP or sit behind a NAT that breaks it. TCP works almost everywhere; UDP is something you confirm, not assume.
How long a free SOCKS5 proxy actually lives
Minutes to hours, not days. Free proxies are shared by a lot of strangers at once, they get overloaded, and whoever exposed them tends to rotate or pull them within hours. Across the 47 million checks our engine has run against public proxies, the pattern does not budge: only a small fraction of any list is working at a given moment, and the working set churns constantly. That is not a knock on any particular source, it is the physics of free.
This is exactly why our list leads with a last-checked timestamp instead of a "verified" badge that could be a week old. "Checked 90 seconds ago and answered" is a claim you can act on. "SOCKS5, France, elite" with no timestamp is a coin flip. When you pull from the list, filter for recently checked entries (recent=true on the API, or the freshness sort on the page) and re-test the specific one you pick.
What the live SOCKS5 slice looks like
The free proxy list carries all four common protocols (HTTP, HTTPS, SOCKS4, and SOCKS5), and the SOCKS5 view is just that pool filtered down to socks5 endpoints. A few honest characteristics of that slice:
- It is mostly datacenter IPs. Like nearly every free pool, the working SOCKS5 entries resolve to hosting networks (Amazon, DigitalOcean, OVH and the like), not home connections. That is fine for testing and wrong for anything that checks whether you look like a real person.
- SOCKS4 is on the list too, and SOCKS5 is the one to grab. SOCKS4 predates authentication, IPv6, and hostname resolution at the proxy. Unless a specific legacy tool demands it, take the SOCKS5 entry.
- It refreshes every few minutes. The set you see now is not the set you saw an hour ago, by design. Dead ones drop off, newly alive ones appear.
None of this makes the free slice useless. It makes it a specific tool: great for "does this endpoint work, what does this page look like from another country, let me test my client's SOCKS support," and wrong for "log into this account" or "check out this cart."
When to stop fighting the free list
If you find yourself re-checking twenty proxies to keep one alive for a job that actually matters, the list is not the problem, the use case is. Free SOCKS5 is built for throwaway work. The moment there is a login, a payment, or a site with real bot defenses on the other end, a free datacenter IP is already flagged before your first request lands, and no amount of re-checking changes that.
That is the line where paid IPs earn their cost. Our residential proxies speak SOCKS5 alongside HTTP, come from real home connections instead of cloud servers, and start at $0.99/GB pay-as-you-go with no KYC, so the protocol choice stays yours while the "you look like a bot" problem goes away.
For everything else, the free list is right there. Pull a SOCKS5 endpoint from /free-proxy-list/socks5, check it right before you use it, and you will get exactly what a free SOCKS5 proxy is good for, no illusions. When the task outgrows that, $0.99/GB residential is the honest next step.
Frequently asked questions
What is a free SOCKS5 proxy list?
It is a list of public SOCKS5 endpoints (an IP, a port, and the SOCKS5 protocol) that anyone can route traffic through for free. The good ones show a last-checked timestamp so you can see which entries were confirmed alive recently, because most free proxies are dead at any given moment. Ours re-checks every few minutes and covers 100+ countries across HTTP, HTTPS, SOCKS4 and SOCKS5.
Are free SOCKS5 proxies safe to use?
They are safe for low-stakes tasks and a bad idea for anything sensitive. SOCKS5 adds no encryption, so a plain-HTTP request through one is readable by the proxy operator, and the IPs are shared datacenter addresses that major sites already flag. Never send logins, payments, or personal data through a free proxy. For testing, geo-checks and throwaway lookups, they are fine.
How do I use a proxy from a free SOCKS5 proxy list?
Point your tool at the IP and port using the SOCKS5 scheme. In curl that is curl -x socks5h://IP:PORT --max-time 10 https://httpbin.org/ip, where the socks5h form makes the proxy resolve DNS so your lookups do not leak locally. If the reply shows the proxy's IP instead of yours, it works.
Why are so many proxies on a free SOCKS5 list dead?
Free proxies are shared by many people, get overloaded, and are rotated or pulled offline within hours. Across our 47 million checks, only a small fraction of any public list is working at a given moment. Always re-test the specific proxy you pick right before you use it, not when you first found the list.
Is SOCKS5 better than HTTP for a free proxy?
Neither is better in general; it depends on the traffic. SOCKS5 carries any TCP (torrents, game clients, SSH, mail) and stays out of your data, while HTTP proxies can cache and rewrite web requests, which some scraping setups want. For plain browsing either works, so use whichever your tool supports.
