Comparison
InstantPWA vs VWO Engage
Push inside a CRO suite, or a standalone install layer?
VWO Engage is one module of VWO's broader conversion-optimisation platform, useful if you are already running VWO for A/B testing elsewhere on the funnel. InstantPWA is a focused, standalone tool for the install-and-notification moment, with its own A/B testing scoped to the install prompt itself.

When to pick which
Use VWO Engage if you are already a VWO customer and want push inside the same suite as your other experiments. Use InstantPWA when you want a dedicated, lightweight install tool without adopting a full CRO platform.
