Hosting your app on VoltBuilder

VoltBuilder Hosting gives your app a persistant place where it can be downloaded.

Normally, apps are only available for download for a short time after they are built. With Hosting, your app will be available for as long as your plan is in effect. This is useful for a organizations which need to make their apps available, but do not want to maintain their own hosting service.

VoltBuilder will return a URL and QR Code (as it does now). You can send these to your customers or employees, who can then use them to install your app directly onto their devices.

Any Android app can be hosted. For iOS, the apps need to be built as Enterprise apps. You’ll need to sign up for Apple’s Enterprise Program. The apps do not need to be uploaded to Google Play or the Apple App Store.

This service is part of the VoltBuilder Enterprise Plan. Please contact to get set up.

For more information, check out the docs.

What VoltBuilder Does

VoltBuilder builds native executables (.apk and .ipa) for Android and iOS from web apps. These executables can be augmented with native code plugins which extend capabilities far beyond what is possible in Web Apps and PWAs.

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

VoltBuilder is framework neutral: it does not use any other AppStudio products, nor does it restrict the use of other frameworks. There is nothing to install.

About Us

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 together 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.
