Comparison

InstantPWA vs PWABuilder

One generates app-store packages. The other gets you the install.

PWABuilder (from Microsoft) is a free tool that takes a PWA and wraps it for the Microsoft, Google and Apple app stores. InstantPWA is the install prompt that runs on your live site to convert browser visitors into PWA installs. They solve different problems and often complement each other.
