The models' case: Best overall default: mature cross-platform purchase infrastructure, remotely configurable native paywalls, segmentation, A/B/n tests, and full-lifecycle revenue. The models' main caveat: Its 1% fee above $2,500 monthly tracked revenue scales poorly, and dedicated paywall tools offer more experimentation depth. The strongest alternative is Superwall — Purpose-built for paywall experimentation — fully remote/no-release paywall config via a placement (\"register\") model, a real rules/targeting engine.
