# 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. ## Docs * Migrate from RevenueCat: https://superwall.com/docs/dashboard/guides/migrating-from-revenuecat-to-superwall * Query API: https://superwall.com/docs/dashboard/guides/query-clickhouse * Webhooks: https://superwall.com/docs/integrations/webhooks * Pricing: https://superwall.com/pricing # SuperwallOptions A configuration class for customizing paywall appearance and behavior. > **Warning:** Only modify `networkEnvironment` if explicitly instructed by the Superwall team. Use `.RELEASE` (default) for production apps. > **Tip:** Use different `SuperwallOptions` configurations for debug and release builds to optimize logging, purchasing behavior, and Google Play settings for each environment. ## Purpose Configures paywall presentation, logging, Google Play purchase behavior, and other global SDK settings. Pass an instance in to [`Superwall.configure`](/docs/android/sdk-reference/configure). ## Signature ```kotlin class SuperwallOptions { var paywalls: PaywallOptions = PaywallOptions() var shouldObservePurchases: Boolean = false var networkEnvironment: NetworkEnvironment = NetworkEnvironment.Release() var eventTrackingBehavior: EventTrackingBehavior = EventTrackingBehavior.ALL @Deprecated("Use eventTrackingBehavior instead.") var isExternalDataCollectionEnabled: Boolean = true var localeIdentifier: String? = null var isGameControllerEnabled: Boolean = false var passIdentifiersToPlayStore: Boolean = false var enableExperimentalDeviceVariables: Boolean = false var logging: Logging = Logging() var useMockReviews: Boolean = false var testModeBehavior: TestModeBehavior = TestModeBehavior.AUTOMATIC } ``` ```java // Java public class SuperwallOptions { public PaywallOptions paywalls = new PaywallOptions(); public boolean shouldObservePurchases = false; public NetworkEnvironment networkEnvironment = new NetworkEnvironment.Release(); public EventTrackingBehavior eventTrackingBehavior = EventTrackingBehavior.ALL; @Deprecated public boolean isExternalDataCollectionEnabled = true; public @Nullable String localeIdentifier = null; public boolean isGameControllerEnabled = false; public boolean passIdentifiersToPlayStore = false; public boolean enableExperimentalDeviceVariables = false; public Logging logging = new Logging(); public boolean useMockReviews = false; public TestModeBehavior testModeBehavior = TestModeBehavior.AUTOMATIC; } ``` ## Parameters ## How `passIdentifiersToPlayStore` affects Google Play Superwall always calls `BillingFlowParams.Builder.setObfuscatedAccountId(Superwall.instance.externalAccountId)` when launching a billing flow. * **Default (`false`)** – `externalAccountId` is a SHA-256 hash of the `userId`. Google Play displays the hashed value as `obfuscatedExternalAccountId`, and the same hash is sent back to your servers. * **Enabled (`true`)** – Superwall forwards the exact `appUserId` you passed to [`identify()`](/docs/android/sdk-reference/identify). This makes it easier to correlate Google Play purchases with your users, but the value must comply with [Google's policy](https://developer.android.com/reference/com/android/billingclient/api/BillingFlowParams.Builder#setObfuscatedAccountId) and must not contain PII. Configure it as part of your application startup: ```kotlin val options = SuperwallOptions().apply { passIdentifiersToPlayStore = true logging.level = LogLevel.info } Superwall.configure( application = this, apiKey = "pk_your_api_key", options = options ) ``` ## Related * [`PaywallOptions`](/docs/android/sdk-reference/PaywallOptions)
