# 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/ # Interactive Paywall Preview The interactive paywall preview shows how your paywall looks on certain iOS devices, for different configurations: > **Warning:** The legacy editor is deprecated. Please visit the docs covering our new > [editor](/docs/dashboard/dashboard-creating-paywalls/paywall-editor-overview). ![1746](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/4.png) The top bar allows you to change the localization of the paywall and the device that it's displayed on: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/5.png) As you mouse-over the paywall, you'll see blue boxes appear highlighting the elements of the paywall that are editable. Clicking on one of these will bring up an editor to the right: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/6.png) This is where you define what the end user sees for the selected element. It contains fields that are relevant to the type of element that's selected. For example, text can be edited in a textfield, and images and videos can be replaced. Above this, you'll see two buttons: **Default** and **Free Trial**: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/7.png) You can click these to toggle between the free trial and default (no free trial) behaviour of the selected element. This also toggles the device preview. When the SDK detects a free trial in any product and the user hasn't already used a free trial within that product's subscription group, it will use the content supplied in the free trial tab. Otherwise it will use the content in the default tab. The free trial tab automatically inherits from the default tab. ### Adding Variables You can show product, user, or device data within text elements by adding a **Variable**. This uses a language called [Liquid](https://shopify.github.io/liquid/basics/introduction/) to substitute in data at runtime. Click the **+ Add Variable** button to choose a variable: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/8.png) This opens a navigation menu from which you can select the data you want to display, along with a preview of what that data looks like: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/9.png) ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/10.png) Clicking on a variable row will insert it inside your textfield with double curly brackets, which tells the device to replace it with real data: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/a447c2e-Screenshot_2022-11-29_at_15.03.06.png) The following objects can be referenced and templated within your paywalls: | Object | Description | Example | User Sees | | --------- | ------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------ | | primary | Product information relating to the *primary product* defined in the *Product section* | `{{primary.trialPeriodDays}`} days free then only `{{primary.price}}` per `{{primary.period}} ` | 7 days free then only $89.99 per year | | secondary | Product information relating to the *secondary product* defined in the *Product section* | Subscribe for only `{{secondary.price}}` per `{{secondary.period}}` | Subscribe for only $4.99 per month | | tertiary | Product information relating to the *tertiary product* defined in the *Product section* | That's only `{{tertiary.weeklyPrice}}` per week! | That's only $2.49 per week! | | user | User attributes your SDK implementation sets on the user. See [Setting User Attributes](/docs/sdk/quickstart/setting-user-properties) | Hey `{{user.firstName}}`! FitnessAI offers tons of `{{user.fitnessGoal}}` workouts to help you reach your goals :) | Hey Sam! FitnessAI offers tons of calorie burning workouts to help you reach your goals :) | | params | Parameters defined when triggering a paywall. See [Showing Paywalls](/docs/sdk/quickstart/feature-gating). | Oh no, you lost! The secret word was `{{params.gameAnswer}}`. Start a free trial to play again! | Oh no, you lost! The secret word was MONEY. Start a free trial to play again! | | device | Device attributes automatically created on device. | Compatible with your `{{ device.deviceModel }`} | Compatible with your iPhone 14 Pro | You can do complex math on these variables using liquid. [Take a look at their documentation](https://shopify.github.io/liquid) for more on how to do that. Additionally, you can use the following device properties: `device.minutesSince_X`, `device.hoursSince_X`, `device.daysSince_X`, `device.monthsSince_X`, and `device.yearsSince_X`, where X is the name of an event that you've [registered](/docs/sdk/quickstart/feature-gating) or a [Superwall event](/docs/sdk/guides/3rd-party-analytics/tracking-analytics). This gives you the days etc since the last occurrence of the event that you specify, excluding the event that triggered the paywall. For example, a paywall presented via an `app_open` event and the text It has been `{{ device.daysSince_app_open}}` since you last opened the app will show `{{ It has been 2 days since you last opened the app }}`. ### AI Powered Suggestions When you edit a textfield, the AI Powered Suggestions section will offer alternative suggestions for your text using OpenAI's gpt3: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/d0bbfb5-Screenshot_2023-06-14_at_18.25.25.png) ### Click Behavior You can set the click behavior of an element by using the **Click Behavior** dropdown: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/db7c993-Screenshot_2022-11-29_at_16.40.53.png) You choose from the following types of click behavior: | Click Behavior | Functionality | | ------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Do nothing | This won't do anything if the user taps on it. | | Open deep link | This will open a deep link. After selecting this you can specify the link to use. We recommend sending deep links to the SDK: [Deep Links & In-App Previews](/docs/sdk/quickstart/in-app-paywall-previews). | | Open URL | This will open a URL from within the paywall. | | Open URL externally | This will open the provided URL in the user's browser. | | Close the paywall | Closes the paywall. | | Restore | Restores purchases via the restorePurchases(completion:) [delegate method](/docs/sdk/quickstart/configure#conforming-to-the-delegate). | | Custom action | Sends the custom action name you provide to the SDK's delegate method handleCustomPaywallAction(withName:). You can use this to perform custom logic from your app as discussed in [Custom Paywall Actions](/docs/sdk/guides/advanced/custom-paywall-actions). | | Purchase primary | Initiates the delegate method purchase(product:) with your primary product identifier. | | Purchase secondary | Initiates the delegate method purchase(product:) with your secondary product identifier. | | Purchase tertiary | Initiates the delegate method purchase(product:) with your tertiary product identifier. | ### Customizing design You can customize the layout, typography, layer, size, margin, padding, corners, effects and background image using the fields below the click behavior: ![](https://2b27b750-superwall-docs-staging.staffbar.workers.dev/docs/images/ad94d77-Screenshot_2022-11-30_at_11.43.34.png)
