# 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 Configuration options for customizing Superwall SDK behavior. ## Purpose Configures various aspects of the Superwall SDK including paywall behavior, logging, and network settings. ## Signature ```dart class SuperwallOptions { PaywallOptions paywalls = PaywallOptions(); NetworkEnvironment networkEnvironment = NetworkEnvironment.release; bool isExternalDataCollectionEnabled = true; String? localeIdentifier; bool isGameControllerEnabled = false; Logging logging = Logging(); bool passIdentifiersToPlayStore = false; TestModeBehavior testModeBehavior = TestModeBehavior.automatic; bool shouldObservePurchases = false; bool shouldBypassAppTransactionCheck = false; // iOS only int maxConfigRetryCount = 6; // iOS only bool useMockReviews = false; // Android only } ``` ## Parameters ## Android-only: `passIdentifiersToPlayStore` Flutter apps can target both iOS and Android. Google Play always consumes the identifier you send through `BillingFlowParams.Builder.setObfuscatedAccountId`, which the SDK sources from `Superwall.instance.externalAccountId`. * When `passIdentifiersToPlayStore` is **`false`** (default) we SHA-256 hash your `userId` before sending it. Play Console and the Superwall backend will show the hashed value. * When it is **`true`**, we pass the exact `appUserId` you supplied to `Superwall.shared.identify`. This only changes behavior on Android—the flag is ignored on iOS builds. Set the option at configuration time when you specifically need the un-hashed identifier: ```dart final options = SuperwallOptions() ..passIdentifiersToPlayStore = true; await Superwall.configure( apiKey, options: options, ); ``` Make sure the identifier complies with [Google's policy](https://developer.android.com/reference/com/android/billingclient/api/BillingFlowParams.Builder#setObfuscatedAccountId) and never contains personally identifiable information. ## Usage Basic options: ```dart final options = SuperwallOptions() ..paywalls = PaywallOptions() ..logging = (Logging()..level = LogLevel.debug); await Superwall.configure( 'pk_your_api_key', options: options, ); ``` Production configuration: ```dart final productionOptions = SuperwallOptions() ..paywalls = (PaywallOptions() ..shouldPreload = true ..automaticallyDismiss = true) ..networkEnvironment = NetworkEnvironment.release ..isExternalDataCollectionEnabled = true ..logging = (Logging()..level = LogLevel.warn); ``` Development configuration (with Play Store IDs on Android): ```dart final developmentOptions = SuperwallOptions() ..paywalls = (PaywallOptions() ..shouldPreload = false ..automaticallyDismiss = false) ..networkEnvironment = NetworkEnvironment.developer ..logging = (Logging() ..level = LogLevel.debug ..scopes = {LogScope.all}) ..passIdentifiersToPlayStore = true; // Android only ``` Custom locale: ```dart final localizedOptions = SuperwallOptions() ..localeIdentifier = 'es_ES' // Spanish (Spain) ..paywalls = (PaywallOptions()..shouldPreload = true); ``` ## Related * [`PaywallOptions`](/docs/flutter/sdk-reference/PaywallOptions)
