Comparison
InstantPWA vs Attentive
SMS-first marketing, or a home-screen install prompt?
Attentive specialises in SMS (and email) marketing for e-commerce, with list growth via on-site popups asking for a phone number. InstantPWA asks for a different, zero-cost-per-message channel — a home-screen PWA install — which then enables free push notifications with no per-message SMS fees.

When to pick which
Use Attentive if SMS is core to your revenue strategy and you need deliverability and compliance tooling for it. Use InstantPWA when you want a free, ongoing channel (push via an installed PWA) instead of, or alongside, paid SMS.
