Every list is scanned, verified and timestamped before it goes up, so you can see country, port, response time and uptime before you copy anything. Lists like these burn out within hours, which is the trade you accept for free. When a job cannot survive that, people move to private proxies with no traffic cap and stop rebuilding their list twice a day.
Scanned and filtered down to what actually answered.
Everything published here is scanned from the open internet, then connected to one by one. A server only makes the list if it completes a SOCKS handshake and returns a page through itself. Response time is measured from Frankfurt, so treat it as a rough sort rather than a guarantee.
Free proxies fail for ordinary reasons. Someone misconfigured a router, a test box got left open, an office firewall was set up wrong. When the owner notices, it closes. Half of any list here is gone within a day, which is why the lists come four times a day instead of once.
Two things behave differently. mobile proxies on real carrier IPs survive because they sit behind a phone operator rather than a forgotten server, and the address rotates on its own. Paid pools survive because someone is paid to keep them alive. Everything else on this page is temporary by nature.
If you are testing something small, take what is here. If you are running accounts, scraping at volume or buying media, the maths stops working quickly. An hour lost to dead addresses costs more than shared and dedicated proxies.
