Is iZooto free?
iZooto offers a free tier with subscriber and feature limits; paid plans unlock higher volume and features.
Can I migrate push subscribers between platforms?
Browser push subscriptions are tied to the site and endpoint, not the vendor, but re-platforming still typically requires re-registering the service worker and vendor SDK.
Does InstantPWA compete with these?
