What is VoltBuilder?

VoltBuilder is a replacement for PhoneGap Build.

It works as a web service. Zip your project, upload to VoltBuilder, and download executables for Android or iOS.

We were users of PhoneGap Build long before they became part of Adobe. One by one, the friends we made at Nitobi drifted away and PhoneGap itself withered. In September, 2020, Adobe announced they were discontinuing the service. There was going to be a big problem unless something was done.

We had the advantage of starting with a clean slate. We were able to simplify and speed up the workflow. We also kept it framework neutral: VoltBuilder does depend on any AppStudio products, nor does it restrict the use of other frameworks. There is nothing to install.

Who is NSB Corporation?

We started in 1993 at the introduction of the Newton to fill the need for easier to use development tools. Our first product, NS Basic/Newton, was a success. When the Newton was cancelled, we introduced NS Basic/Palm. It also did well, so we added NS Basic/CE.

In 2010, we realized that JavaScript on mobile devices was getting fast. Web pages in those days used a bit of JavaScript to augment the page: Could we flip things around and make JavaScript the core of web pages, driving the HTML and CSS? That resulted in AppStudio, targeting iOS and Android. It now has thousands of users in over 80 countries. More than 2 million students have learned how to program using it.

The same core group of developers has been at work on AppStudio for many years. We enjoy what we’re doing - we’ve built a loyal base of customers by treating them fairly and providing great support.
