Free Proxy Tools
Before a line goes to a customer we run these two checks ourselves, and anyone can use them. No sign-up, nothing stored.
Go deeper with IPFighter
We send customers to IPFighter's free suite for browser fingerprinting, bot detection, DNS and WebRTC leak tests, and it works well next to a Chicago Proxies line:
IP score & lookup ↗ Browser fingerprint ↗ Bot detection ↗ DNS leak test ↗ WebRTC leak test ↗ IPFighter proxy checker ↗
Recommended antidetect browsers
Which antidetect browser works with a Chicago line? Undetectable.io is our first recommendation: one profile per Chicago line, time zone set to Central and language to en-US, then paste the HTTP or SOCKS5 details and run the check. GoLogin is our second pick.
Undetectable.io
Starts on a free plan, runs on Windows and macOS, with local and cloud profiles. Give each profile its own Chicago Proxies line.
