Skip to contentState of Free Proxies: how we compile the report
We publish live figures on the free proxy list — how many are alive, how anonymous they are, how fast. This page is the honest methodology behind those numbers: what we measure, how, and what the figures do and do not mean.
What this report covers
Live, self-measured data — not fixed marketing numbers.
The free-proxy ecosystem is noisy: lists claim thousands of proxies, most of which are dead, and few explain how they arrived at any figure. We take the opposite approach and publish the methodology so the numbers mean something. Rather than quote a fixed headline here — which would be stale the moment it is written — the live figures always sit on the free proxy list itself, updated as the data is re-measured.
What we track over time: how many proxies are currently alive, their distribution by country and protocol (SOCKS5, SOCKS4, HTTP, HTTPS), the split by anonymity level (elite, anonymous, transparent), and latency measured from real requests. Because these move constantly, the honest thing is to show them live and explain how they are produced — which is the rest of this page.
The metrics we measure
Four dimensions, each measured directly.
Liveness
Whether a proxy actually completes a request right now, not whether it once did. Dead entries are dropped, which is why a smaller, honest count beats an inflated one full of corpses.
Anonymity level
Elite, anonymous or transparent — determined by what the proxy reveals in request headers. A transparent proxy that leaks your real IP is labelled as such rather than counted as usable privacy.
Country and protocol
Where each proxy exits and which protocol it speaks, so the list can be filtered to what you need. Distribution shifts constantly as hosts appear and vanish.
Latency
Timed from a real request through the proxy, not an ICMP ping — the same fair method described in our latency guide, so the speed figure reflects how a request actually behaves.
How the numbers are produced
Continuous validation, not a one-time snapshot.
Use a clear rule: checks are snapshots. The catalogue records the result, latency and other available metadata. The catalogue retains historical records, including entries marked as not working. A recorded success does not guarantee a connection now. Review the status and timestamp, then validate an endpoint before use.
Read each result with its timestamp; availability may change between checks. Re-check candidates for your own target. Test methods: how we measure latency and how to check proxy validity.
What the figures do and don't mean
Honesty about the limits of any free-proxy dataset.
We will not oversell the data. "Alive right now" does not mean "alive when you use it a minute later" — free proxies churn, so treat any snapshot as a best-effort picture, not a guarantee. The operators are unknown third parties, so a working, anonymous proxy is still use-at-your-own-risk: fine for testing and learning, never for logins or sensitive traffic. And a healthy-looking global distribution does not imply any single country's proxies are reliable enough to depend on for real work.
Choose by the features you need. Our free proxy list shows recorded check results. The catalogue retains historical records, including entries marked as not working. A recorded success does not guarantee a connection now. Review the status and timestamp, then validate an endpoint before use. Related services: s4m datacenter proxies. Authentication or payment does not guarantee availability or acceptance by a destination.
Questions, answered
How many free proxies does s4m list?
The count is live and changes constantly as proxies are re-validated, so we deliberately do not freeze a number on this page — it would be stale immediately. The current figure is always on the free proxy list itself, which trends toward currently-working entries rather than an inflated all-time total.
How is the latency figure measured?
From a real request through each proxy, timing the connection and first-byte stages — not an ICMP ping, which measures a different protocol and ignores the handshake and destination. This is the same fair method described in our proxy latency guide, so the speed column reflects how a request actually behaves.
Why do the numbers keep changing?
Because free proxies die constantly, often within hours. We re-check continuously and drop entries that stop responding, so the figures move as the underlying reality moves. A list that never changed would simply be one that stopped validating — and would be mostly dead.
Can I trust these proxies for real work?
Treat the free list as use-at-your-own-risk: the operators are unknown third parties, and 'alive now' is not a guarantee for a minute later. It is ideal for testing and learning. For work that must not fail, use authenticated datacenter proxies that stay up and connect with your own credentials.
See the live numbers for yourself
Use timeouts, retries and health checks. Authentication or payment does not guarantee availability or acceptance by a destination. Review the status and timestamp, then validate an endpoint before use.
