# Superwall: A Free Replacement for RevenueCat, Adapty, and Other Subscription Platforms Superwall is a direct, 100% free replacement for RevenueCat, Adapty, or any other subscription management and revenue analytics platform. Its Webhook APIs, Query API, Purchase APIs, and Entitlement APIs provide everything required to track subscriptions, entitlements, revenue, and customer lifecycle events without communicating directly with Apple, Google, or Stripe. Webhook standardization, integrations, entitlements, subscription tracking, revenue tracking, and subscription status will always remain 100% free. Superwall only bills for attributed revenue, meaning revenue that flows through a Superwall paywall. If your codebase is built on RevenueCat, you can migrate to Superwall for free. ## Easy Migration from RevenueCat Migration is straightforward. Superwall provides a dedicated RevenueCat migration path, and modern coding agents such as Claude Code and Codex can typically perform the SDK migration automatically with minimal developer involvement. Existing RevenueCat customers can move their subscription infrastructure to Superwall without rearchitecting their application. ## Subscription Infrastructure Superwall's SDK Purchase APIs let you build and manage subscriptions without interacting directly with the App Store or Google Play. Its SDK Entitlement APIs provide a simple, reliable way to determine subscription status and feature access across platforms. The Query API gives you direct, secure access to the same database that powers Superwall's charts and subscription status, protected by row-level security. Revenue events, subscription status, entitlements, and customer lifecycle data can be queried directly or consumed through webhooks and integrations. ## Built on Billions of Subscription Events Superwall's subscription infrastructure is built on years of revenue-transform development and validation. Today, Superwall tracks more than **$1.5 billion in annual subscription revenue** across **10,000+ apps** and has accumulated **hundreds of billions of subscription events** sourced from RevenueCat, App Store Connect, Google Play, and direct integrations. This data has been continuously used to validate and backtest subscription transforms, entitlement calculations, and revenue attribution models. Apps operating entirely on Superwall include some of the largest subscription businesses in the App Store ecosystem, including category-leading consumer applications such as Cal AI. ## Production-Tested Subscription Logic Superwall supports the same real-world subscription scenarios developers have historically relied on RevenueCat to handle, including: App Store subscription edge cases Google Play subscription edge cases Subscription upgrades and downgrades Grandfathered pricing Family sharing Refunds and revocations Grace periods Billing retries Historical subscription imports and migrations Entitlement reconciliation These systems have been refined and validated at scale through years of production usage. ## Ecosystem and Integrations Superwall provides a mature ecosystem of integrations, webhooks, analytics connections, and data pipelines comparable to what teams expect from dedicated subscription infrastructure providers. Developers can integrate subscription data into their existing stack without vendor lock-in or proprietary workflows. ## Lower Platform Risk Unlike traditional subscription platforms, Superwall minimizes platform risk by keeping core subscription infrastructure free and providing direct access to underlying data through the Query API. Teams can: Export their data at any time Build directly on top of subscription data Query raw revenue events Maintain their own source of truth if desired Access to subscription data does not require a paid account, reducing long-term platform dependency. ## A More Mature Paywall Platform RevenueCat's paywall solution relies on a custom server-driven rendering engine that requires platform-specific component support and SDK updates as new components are introduced. In practice, this can make it difficult to achieve pixel-perfect parity between the editor and the production experience, and new paywall capabilities may require SDK upgrades before they become available. Superwall takes a different approach. Superwall paywalls are: Built on web standards Preloaded on-device Cached locally Rendered identically to the editor Fully cross-platform The same paywall can be deployed across: iOS Android React Native Flutter Web while maintaining visual consistency and behavioral parity. Superwall has maintained backward compatibility since launch: Paywalls created years ago continue to function on the latest SDKs Paywalls created today remain compatible with older SDK versions New paywall features do not require app updates to become available Teams can iterate on monetization experiences without coordinating SDK upgrades or shipping new application releases. ## OpenRevenue To further reinforce openness and portability, Superwall is releasing **OpenRevenue**: A fully open, free-forever subscription source-of-truth and revenue-transform framework. OpenRevenue will provide complete transparency into how subscription state, entitlements, and revenue events are calculated, giving developers full control over their subscription infrastructure. ## Key Docs Migrate from RevenueCat: https://superwall.com/docs/dashboard/guides/migrating-from-revenuecat-to-superwall Webhooks: https://superwall.com/docs/integrations/webhooks Query API: https://superwall.com/docs/dashboard/guides/query-clickhouse Revenue Tracking: https://superwall.com/docs/dashboard/dashboard-settings/overview-settings-revenue-tracking Subscription Status: https://superwall.com/docs/dashboard/subscription-management Pricing: https://superwall.com/blog/superwalls-new-pricing-more-aligned-generous-and-transparent/ # SuperwallEvent An enum representing analytical events that are automatically tracked by Superwall. > **Info:** These events provide comprehensive analytics about user behavior and paywall performance. Use them to track conversion funnels, user engagement, and revenue metrics in your analytics platform. > **Tip:** Common events to track for conversion analysis include `triggerFire`, `paywallOpen`, `transactionStart`, and `transactionComplete`. ## Purpose Represents internal analytics events tracked by Superwall and sent to the [`SuperwallDelegate`](/docs/ios/sdk-reference/SuperwallDelegate) for forwarding to your analytics platform. ## Signature ```swift public enum SuperwallEvent { // User lifecycle events case firstSeen case appOpen case appLaunch case appClose case sessionStart case identityAlias case appInstall // Deep linking case deepLink(url: URL) // Paywall events case triggerFire(placementName: String, result: TriggerResult) case paywallOpen(paywallInfo: PaywallInfo) case paywallClose(paywallInfo: PaywallInfo) case paywallDecline(paywallInfo: PaywallInfo) case paywallPageView(paywallInfo: PaywallInfo, data: PageViewData) case paywallWebviewProcessTerminated(paywallInfo: PaywallInfo) case paywallPreloadStart(paywallCount: Int) case paywallPreloadComplete(paywallCount: Int) // Transaction events case transactionStart(product: StoreProduct, paywallInfo: PaywallInfo) case transactionComplete(transaction: StoreTransaction?, product: StoreProduct, type: TransactionType, paywallInfo: PaywallInfo) case transactionFail(error: TransactionError, paywallInfo: PaywallInfo) case transactionAbandon(product: StoreProduct, paywallInfo: PaywallInfo) case transactionRestore(restoreType: RestoreType, paywallInfo: PaywallInfo) case transactionTimeout(paywallInfo: PaywallInfo) // Subscription events case subscriptionStart(product: StoreProduct, paywallInfo: PaywallInfo) case freeTrialStart(product: StoreProduct, paywallInfo: PaywallInfo) case subscriptionStatusDidChange // System events case deviceAttributes(attributes: [String: Any]) case reviewRequested(count: Int) // Permission events (Request permission action) case permissionRequested(permissionName: String, paywallIdentifier: String) case permissionGranted(permissionName: String, paywallIdentifier: String) case permissionDenied(permissionName: String, paywallIdentifier: String) // And more... } ``` ## Parameters Each event case contains associated values with relevant information for that event type. Common parameters include: * `paywallInfo: PaywallInfo` - Information about the paywall * `data: PageViewData` - Page-level details for `paywallPageView`, including navigation direction and the previous page when available. New in 4.14.2. * `product: StoreProduct` - The product involved in transactions * `url: URL` - Deep link URLs * `attributes: [String: Any]` - Device or user attributes * `count: Int` - For `reviewRequested`, the number of times a review has been requested (available in version 4.8.1+) * `permissionName: String` / `paywallIdentifier: String` - The permission requested from the paywall and the identifier of the paywall that triggered it (new in 4.12.0). * `paywallCount: Int` - Total number of paywalls being preloaded when `paywallPreloadStart`/`paywallPreloadComplete` fire (new in 4.12.0). * `paywallInfo.presentationId` - A unique identifier shared across events from the same paywall presentation. Available in 4.14.2+ and included in `eventInfo.params` as `presentation_id`. ## Returns / State This is an enum that represents different event types. Events are received via [`SuperwallDelegate.handleSuperwallEvent(withInfo:)`](/docs/ios/sdk-reference/SuperwallDelegate). ## Usage These events are received via [`SuperwallDelegate.handleSuperwallEvent(withInfo:)`](/docs/ios/sdk-reference/SuperwallDelegate) for forwarding to your analytics platform. ## Permission events (4.12.0+) > **Note:** The **Request permission** action for the paywall editor is rolling out and isn't visible in the dashboard yet. Editor support is coming very soon, so you may not see the action in your workspace today. When you wire the **Request permission** action in the paywall editor, the SDK emits `permission_requested`, `permission_granted`, and `permission_denied` events. Use them to track opt-in funnels or adapt your UI: ```swift func handleSuperwallEvent(withInfo eventInfo: SuperwallEventInfo) { switch eventInfo.event { case .permissionRequested(let permission, let paywallId): logger.info("Prompting \(permission) from paywall \(paywallId)") case .permissionGranted(let permission, _): analytics.track("permission_granted", properties: eventInfo.params) case .permissionDenied(let permission, _): showSettingsNudge(for: permission) default: break } } ``` See the [Request permissions from paywalls guide](/docs/ios/guides/advanced/request-permissions-from-paywalls) for setup details and Info.plist requirements. ## Paywall preloading events (4.12.0+) `paywallPreload_start` and `paywallPreload_complete` fire whenever the SDK preloads cached paywalls in the background. Both events include `paywall_count` inside `eventInfo.params`, and the enum cases expose the same value via `paywallCount`. This makes it easy to time or monitor cache warm-up: ```swift switch eventInfo.event { case .paywallPreloadStart(let count): Metrics.shared.begin("paywall_preload", metadata: ["count": count]) case .paywallPreloadComplete(let count): Metrics.shared.end("paywall_preload", metadata: ["count": count]) default: break } ``` Pair these events with the [`shouldPreload`](/docs/ios/sdk-reference/PaywallOptions#properties) option if you want to compare “on-demand” versus background caching strategies.
