My search for free proxy list providers led me to Spys.one’s massive database, which is one of the largest collections I’ve tested.
Spys.one Features
Spys.one’s interface comes packed with practical features. The platform has a big selection of IP addresses from 178 countries that get updated often. Their complete protocol support caught my eye with:
HTTP/HTTPS compatibility
SOCKS protocol integration
Squid proxy support for UNIX/Linux platforms
The reliable filtering system lets me sort proxies by city, country, and type. Each proxy listing shows vital metrics like latency, speed, and uptime ratings.
Spys.one Security Implementation
Spys.one groups proxies into three distinct anonymity levels:
NOA (Non-Anonymous)
ANM (Anonymous)
HIA (High Anonymous)
The platform uses load balancing techniques and optimized network protocols to deliver consistent performance in each session.
Spys.one Server Coverage
Their server infrastructure shows impressive coverage:
Access to over 29,000 proxies in approximately 180 countries
Brazil, Germany, and United States lead with 800+ proxies each
Servers maintain 70% average uptime
Their up-to-the-minute proxy checking system works great. They verify 25% of all proxies within 24 hours and another quarter within a week. This regular verification keeps the list reliable, though proxies from less common locations might take longer to check.
The biggest problem I found was that you can’t export or sort the proxy list. This makes managing multiple proxies a bit tricky. But the complete filtering options make up for this limitation.
