No. The JavaScript Beautifier runs entirely in your web browser, so your text and numbers stay on your device and work even on a slow connection.

Yes. The JavaScript Beautifier runs in any modern browser (Safari, Chrome, Edge or Firefox) on iPhone, iPad, Android phones, Mac, Windows and Chromebook. There is no app to install.
