Ionic Appflow vs VoltBuilder

Ionic AppFlow is one of the most widely used build tools for mobile apps. Not surprising - it’s been around for a few years.

How does it compare to VoltBuilder, a much newer product? Let’s compare them.

The major difference is that Ionic Appflow is completely an online service: all your source code, certificates and passwords are saved on Ionic’s servers. A nice user interface lets you maintain your apps on their server. VoltBuilder only stores your app as long as needed1: your project is saved on your local system. Apps are submitted by drag and drop.

Each product has additional features not listed here: Ionic Appflow has GitHub and CI/CD integration and live OTA updates. VoltBuilder has App Hosting, QR Codes for device downloading and iOS/Android Certificate Generation.
