Free Proxy Tools
Open to everyone, these are the two checks we run ourselves before a line goes to a customer. No sign-up, nothing stored.
What IP am I on? See the carrier, ASN, city, WebRTC leak and time-zone match at a glance.
Free toolProxy checkerPaste a single proxy or a full list (HTTP, HTTPS, SOCKS4, SOCKS5) for exit IP, location, ISP and latency on each line, then export those that work.

Recommended antidetect browsers
Which antidetect browser do you recommend for a marketing team? Undetectable.io first: one profile per market, each pinned to its own Stateside line, with US English and the line's time zone. GoLogin is the second pick and suits teams that share profiles through the cloud. Both have free plans.
Undetectable.io
Starts with a free plan; Windows and macOS; profiles local or in the cloud. Give each profile its own Stateside Proxies line.

Go deeper with IPFighter
We send customers to IPFighter's free suite for browser fingerprinting, bot detection, and DNS and WebRTC leak tests, and it sits well beside a Stateside Proxies line:
