Where InstantPWA fits
Neither is focused on the install/home-screen moment for a PWA — both are general marketing/CRO suites with push as one feature. InstantPWA is a narrower, dedicated tool for the install prompt specifically, without requiring adoption of a broader marketing suite.

Can I buy just the push feature from either vendor?
Typically no — push is bundled within a broader plan tier in both suites; check current plan pages for exact packaging.
Is either suite free?
Both offer trials; ongoing free tiers are limited — confirm current pricing directly with each vendor.
Does InstantPWA overlap with these suites?
Only at the push-notification feature level; InstantPWA does not offer general CRO, popups or heatmaps.
