Take the uncertainty out of localization testing

Scalable testing options and a global network of proxy servers, right at your fingertips. No more guesswork.

Made by developers, for developers

Testing locale-specific code when you're stuck at your desk is like flying blind: you can't see where you're going. From our versatile testing solutions to our worldwide network of proxy servers, WonderProxy is built for localization testing. Squash those bugs and ship that next release.

Global reach

We have servers in 259 cities on six continents, covering over 97% of the world's GDP. Chances are if you've got users there, we've got a server. Unless they're in Antarctica. 🐧

Built with transparency

Unlike some competitors, we don't send your traffic through hacked residential devices. We've built our network exclusively for localization testing, and we monitor it carefully to keep it free from unauthorized activity.

No funny business

Our servers are where we say they are, and we don't modify your content. WonderProxy preserves your website exactly as you built it. Test your user experience, for real—no hacks, no ads, no injections.

Ready when you are

Our server status page lets you keep an eye on all your mission-critical servers. If a server's acting up, swap to another one nearby and keep on working. We'll work to get it back online ASAP.

We wouldn't be able to develop or test our geo-targeted applications without it. WonderProxy is a vital tool in our software development process.
