Proxy Checker

Why Check Proxies?

Proxy servers are essential tools for web scraping, SEO monitoring, social media management, and bypassing geo-restrictions. However, free and even paid proxy lists "die" over time: servers go down, IPs get banned, ports change. Using non-working proxies leads to wasted time, script errors, and automation failures.

Our proxy checker lets you quickly filter out dead proxies and keep only working ones. You upload a list of up to 100 proxies, and within seconds you get a results table: status (alive/dead), latency in milliseconds, detected protocol, and country.

How to Use?

Paste proxies in IP:PORT format (one per line) into the text field. Click "Check". The system will check each proxy in parallel, attempting to establish a connection and detect the protocol (HTTP, HTTPS, SOCKS5). Results are displayed in real-time.

Technical Details

Each proxy is checked with a 10-second timeout. We try connecting to a test server through the specified proxy, measuring response time. Parallel checking allows processing up to 100 proxies in 15-20 seconds. Geolocation is determined using the MaxMind GeoIP2 database.
