Frequently asked questions
Is the What Is My Browser free to use?
Yes. What Is My Browser on ToolNest is completely free, with no sign-up, no watermark and no daily limits.
Is my data stored?
No. Most checks run entirely in your browser. Tools that must contact a network service — such as the speed test or IP lookup — only send what is needed to get the result, and we never store it.

Yes. ToolNest works in any modern browser on Android, iPhone, iPad, Windows, Mac and Linux. There is nothing to install.
