USA 5G Proxies Proxy Tester
Speed is a claim until you time it on your own machine. The desktop tester opens real connections through each 5G line, reports carrier, city and round trip per row, and keeps the fast ones.
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.
