Free Proxy Tools
These are our own two checks before a line goes to a customer, and anyone can use them. No sign-up, nothing stored.
Recommended antidetect browsers
Does a day pass work with an antidetect browser? Yes. We recommend Undetectable.io: one profile per day pass, the line's host, port, username and password in the proxy field, time zone and language set to the city. GoLogin is our second choice and works the same way.
Undetectable.io
Free plan to start, works on Windows and macOS, keeps local and cloud profiles. Give each profile its own 4G Proxies USA line.
Get Undetectable.io ↗GoLogin
Free plan comes with 3 profiles, and it works on Windows, macOS, Linux and phones. Use host:port:user:pass when you paste the 4G Proxies USA line.
Get GoLogin ↗Partner links. Any antidetect browser taking HTTP or SOCKS5 proxies works with our lines, but these two are what we recommend.
Go deeper with IPFighter
We tell customers to use IPFighter's free suite for browser fingerprinting, bot detection, DNS and WebRTC leak tests, since it works well with a 4G Proxies USA line:
IP score & lookup ↗ Browser fingerprint ↗ Bot detection ↗ DNS leak test ↗ WebRTC leak test ↗ IPFighter proxy checker ↗
