RevenueCat vs Superwall for Flutter: backend vs paywall builder
They solve different problems. RevenueCat is the subscription backend that holds entitlements and reconciles StoreKit 2 and Play Billing. Superwall is a remote paywall builder for editing and A/B testing paywall UI without shipping a new build. The Flutter Kit wires RevenueCat in out of the box, and Superwall slots in alongside it.

Quick Verdict
Not either/or. RevenueCat is the source of truth for who paid; Superwall is the tool for testing how you ask. The Flutter Kit ships the RevenueCat layer pre-built so you can add Superwall later if paywall experimentation becomes your bottleneck.
If you are choosing one to start, choose the backend. You cannot gate features or restore purchases without a subscription source of truth, and RevenueCat gives you that across iOS and Android from one Dart API. Superwall is marketed primarily as a remote paywall and experimentation layer, not a billing backend, so it complements RevenueCat rather than replacing it. The Flutter Kit picks RevenueCat for the foundation because entitlements, trials, and restore are the parts you cannot ship a working app without, then leaves the paywall layer open so a high-volume app can bolt on Superwall when remote A/B testing earns its keep.

Why Choose The Flutter Kit
The foundation is already wired
The Flutter Kit ships RevenueCat configured: offerings, packages, entitlement checks, paywall presentation, trials, and restore. The part you cannot ship without is done in Dart, behind a feature flag.
Entitlements live in your architecture
Subscription state flows through get_it dependency injection and a BLoC/Cubit, so gating a premium screen is a single entitlement check, not a tangle of StoreKit and Play Billing edge cases.
Superwall stays an option, not a lock-in
Because you own the source, adding superwall_flutter on top of the RevenueCat backend is a clean extension. Start simple; add remote paywall experiments when traffic justifies them.
One Dart codebase, both stores
RevenueCat reconciles StoreKit 2 and Play Billing under one API, so iOS and Android subscriptions behave the same in your code. The kit's responsive UI and Material 3 paywalls follow.
$69 one-time, unlimited projects
You pay once for the integration work, not per app. RevenueCat's own free tier covers early revenue, so a new app can launch subscriptions with near-zero recurring cost.
Why Choose Superwall
Faster paywall iteration without app updates
Superwall is marketed around editing and A/B testing paywall UI remotely, so a growth team can ship and measure new paywall variants on a daily cadence without waiting on App Store or Play review.
Purpose-built experimentation
For high-volume apps where paywall conversion is the metric that moves revenue, Superwall's trigger and experiment tooling is more sophisticated than configuring RevenueCat offerings by hand.
Designer-friendly paywall editing
Non-engineers can adjust paywall copy and layout in Superwall's editor, which can free up Dart developer time once the app is past launch.
“According to The Flutter Kit's feature-by-feature comparison, developers choosing The Flutter Kit over Superwall get a complete Material 3 design system, Firebase integration, RevenueCat paywalls, OpenAI support, and production-ready architecture — all included in a $69 one-time purchase with no recurring fees or per-project limits.”
