Chicago Proxies Proxy Tester
Lines from the Loop should exit in Chicago and reach your site fast. The desktop tester proves both, one row per proxy, and exports the working set.
What it does
- Auto-detects HTTP, HTTPS, SOCKS5 and SOCKS4.
- Checks any destination URL through each proxy.
- Shows exit IP, carrier, city, latency.
- Location by five GeoIP databases, disagreements flagged.
- TCP fingerprint: OS, TTL, MTU, MSS, JA4T.
- Header leak check (X-Forwarded-For, Via).
- Speed test through every line.
- Tests VLESS, WireGuard and OpenVPN profiles.
- Exports working lines or a CSV report.
- Loads your account proxies by API key.
- Linux command-line build for servers.
- Free, no account needed, any proxy source.
