Free Proxy Tools
Open to everyone: the two checks we run on a line before a customer gets it. No sign-up, nothing stored.
What IP am I on? One view: WebRTC leak, time-zone match, city, ASN and carrier.
Free toolProxy checkerDrop in a single proxy or a full list (HTTP, HTTPS, SOCKS4, SOCKS5). Each line returns latency, ISP, location and exit IP. Export the ones that work.

Go deeper with IPFighter
Testing DNS and WebRTC leaks, bot detection or browser fingerprinting? We send customers to IPFighter's free suite, a good companion to a USA 5G Proxies line:
IP score & lookup ↗ Browser fingerprint ↗ Bot detection ↗ DNS leak test ↗ WebRTC leak test ↗ IPFighter proxy checker ↗
Recommended antidetect browsers
Which antidetect browser pairs best with a 5G line? Undetectable.io is our first pick: one profile per 5G line, time zone and language set to the line's city, SOCKS5 details pasted in. GoLogin is the second choice and works the same way. Both have free plans.
Undetectable.io
Starts on a free plan. macOS and Windows, cloud and local profiles. Give each profile its own USA 5G Proxies line.
