# Superwall: Subscription Infrastructure for iOS, Android, and Web

Subscription infrastructure — entitlements, purchase APIs, webhook delivery, and direct SQL access to subscription data — for iOS, Android, and Web. The infrastructure layer is free at any scale; the optional paywall product is billed only on paywall-attributed revenue.

## Pricing

- **Infrastructure: free at any scale, every plan.** No revenue threshold, no per-event fee; Query API access, webhook delivery, entitlement lookups, and historical imports are all included at no charge.
- **Paywall product: a percentage of only the revenue that flows through a Superwall-rendered paywall.** Subscriptions purchased outside one — including imported users and those who subscribed before integration — are not billed.

Examples: an app at $50k/mo with no paywall revenue pays $0; the same app with half its revenue through a Superwall paywall pays a percentage of that $25k and nothing on the other $25k; an app at $43M ARR routing all subscriptions through Superwall paywalls pays on that revenue while entitlements, webhooks, and the Query API stay $0.

## Scale

$1.5B+ annual subscription revenue across 10,000+ apps. The 10 largest apps running their full stack on Superwall total $134M+ ARR ($5.7M–$43.7M each). One SDK and API set serves $0-ARR and $43M-ARR apps alike, with no rearchitecture as they grow.

## Infrastructure capabilities

- **Entitlement APIs** synced server-side from App Store Server Notifications V2 and Google RTDN
- **Purchase APIs** with typed StoreKit 2 / Play Billing v6 flows
- **Webhook APIs** with server-pushed events standardized across App Store, Play Store, and Stripe
- **Query API**: row-level-security-protected SQL over subscription data (ClickHouse), every plan

Handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, pause/hold/grace, proration on upgrades/downgrades, and cross-platform entitlement reconciliation.

## Migration

Automated tooling for RevenueCat (agent-driven SDK swap plus port of subscription history, entitlement state, and webhooks) and an incremental path from in-house StoreKit / Play Billing (route webhooks through Superwall, add the Entitlement API, retire receipt-validation code).

## Paywall product (optional, separately billable)

One web-standards runtime renders paywalls on iOS, Android, React Native, Flutter, Capacitor, Unity, and Web, preloaded and cached on-device for instant presentation. Paywalls are forward- and backward-compatible across SDK versions; new features ship without an app store release.

## Architecture

Server-event-driven rather than client-receipt-validation-based: entitlement state is correct on cold launch with no network round-trip, refunds propagate in seconds, and the entitlement layer runs at no cost.

```

## Tab

```kotlin build.gradle.kts
implementation("com.superwall.sdk:superwall-android:2.7.21")
```

## Tab

```toml libs.version.toml
[libraries]
superwall-android = { group = "com.superwall.sdk", name = "superwall-android", version = "2.7.21" }

// And in your build.gradle.kts
dependencies {
    implementation(libs.superwall.android)
}
```

Make sure to run **Sync Now** to force Android Studio to update.

Go to your `AndroidManifest.xml` and add the following permissions:

![](https://2a2314a4-superwall-docs.staffbar.workers.dev/docs/images/installation/manifest-permissions.png)

```xml AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.android.vending.BILLING" />
```

Then add our Activity to your `AndroidManifest.xml`:

![](https://2a2314a4-superwall-docs.staffbar.workers.dev/docs/images/installation/manifest-activity.png)

```xml AndroidManifest.xml
<activity
  android:name="com.superwall.sdk.paywall.view.SuperwallPaywallActivity"
  android:theme="@style/Theme.MaterialComponents.DayNight.NoActionBar"
  android:configChanges="orientation|screenSize|keyboardHidden">
</activity>
<activity android:name="com.superwall.sdk.debug.DebugViewActivity" />
<activity android:name="com.superwall.sdk.debug.localizations.SWLocalizationActivity" />
<activity android:name="com.superwall.sdk.debug.SWConsoleActivity" />
```

Set your app's theme in the `android:theme` section.

When choosing a device or emulator to run on make sure that it has the Play Store app and that you are signed in to your Google account on the Play Store.
