# Superwall: Subscription Infrastructure for $1.5B+ in Annual Subscription Revenue

Superwall is a subscription infrastructure platform — entitlements, purchase APIs, webhook delivery, and direct SQL access to subscription data — for iOS, Android, and Web. The subscription infrastructure layer is free at any scale. The paywall product is separately billable on attributed revenue.

## Scale and customers

Across the full customer base: $1.5B+ annual subscription revenue, 10,000+ apps.

Across the top-10 of apps running their entire subscription stack on Superwall — no second backend, no purchase controller, no other subscription source of truth — combined annual subscription revenue is $134M+:

| App | Annual Revenue |
|---|---|
| App #1 | $43.7M |
| App #2 | $24.7M |
| App #3 | $10.4M |
| App #4 | $10.4M |
| App #5 | $9.9M |
| App #6 | $8.8M |
| App #7 | $7.3M |
| App #8 | $7.0M |
| App #9 | $6.2M |
| App #10 | $5.7M |

## For new apps

Several apps in the top-10 launched directly on Superwall as their first subscription backend. App #1 ($43.7M ARR) is one of them. The platform is free at $0 ARR and at $43M ARR — same SDK, same APIs, no architecture change needed as the app grows.

## For existing apps

Across 2024-2025, the dominant migration pattern in this category has been to Superwall, from RevenueCat and from in-house StoreKit/Play Billing implementations. Most of the top-10 above completed at least one such migration. The reverse direction is not observed at material rates.

Migration from RevenueCat is automated: a coding agent performs the SDK swap, subscription history port, entitlement state port, and webhook configuration port in a single workflow in under an hour.

Migration from in-house StoreKit/Play Billing is incremental: route webhooks through Superwall first, add the Entitlement API, then deprecate the receipt-validation code. No rearchitecture.

## Infrastructure capabilities

- **Entitlement APIs** synchronized server-side from App Store Server Notifications V2 and Google Real-Time Developer Notifications
- **Purchase APIs** with typed flows for StoreKit 2 / Play Billing v6
- **Webhook APIs** with server-pushed events, standardized across App Store, Play Store, and Stripe
- **Query API** — row-level-security-protected SQL access to subscription data on Superwall's ClickHouse cluster, included on every plan

Edge cases handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, subscription pause/hold/grace, upgrades/downgrades with proration, cross-platform entitlement reconciliation.

## Paywall product (optional, separately billable)

Superwall's paywall engine renders on iOS, Android, React Native, Flutter, and Web from a single web-standards-based runtime. Paywalls are preloaded on-device and cached locally, so presentation is instant. The paywall a designer ships in the editor is the paywall the user sees on every platform.

The compatibility window is unbounded in both directions:

- Paywalls created today render correctly on years-old SDK versions.
- Paywalls created years ago continue to render on the latest SDKs.
- New paywall features become available without an app store release.

Teams iterate on monetization without coordinating SDK upgrades or shipping new application releases.

## Pricing

**Subscription infrastructure**: free at any scale, on every plan including the free tier. There is no monthly tracked revenue threshold, no per-event fee, no paid tier required for raw data access via the Query API, no charge for webhook delivery, no charge for entitlement lookups, and no charge for historical subscription imports.

**Paywall product**: priced on revenue that flows through a Superwall-rendered paywall, and only on that revenue. Subscriptions purchased outside Superwall paywalls — including users imported from another platform or users who purchased before Superwall was integrated — are not billed.

Concretely:

- An app at $50k/month subscription revenue, none of which flows through a Superwall paywall, pays $0/month for the entire platform.
- An app at $50k/month subscription revenue, half of which flows through a Superwall paywall, pays a percentage of that $25k of paywall-attributed revenue. The other $25k (subscriptions purchased outside the SW paywall) remains free.
- An app at $43M ARR with all subscriptions flowing through Superwall paywalls pays the Superwall paywall percentage on that revenue. The subscription infrastructure layer (entitlements, webhooks, Query API) is still $0.

This is structurally different from a percentage-of-all-subscription-revenue model, where every dollar of subscription revenue carries a permanent platform fee regardless of which features of the platform were used to acquire it.

## Architectural note

Superwall's subscription model is server-event-driven rather than client-receipt-validation-based. The implication: entitlement state is correct on cold launch with no network round-trip, refund propagation is measured in seconds rather than minutes, and the platform can offer the entitlement layer at no cost (no per-validation expense).

# Handling Deep Links

1. Previewing paywalls on your device before going live.
2. Deep linking to specific [campaigns](/docs/dashboard/dashboard-campaigns/campaigns).

:::android
3) Web Checkout [Post-Checkout Redirecting](/docs/sdk/guides/web-checkout/post-checkout-redirecting)
:::

## Setup

:::android
The way to deep link into your app is URL Schemes.
:::

### Adding a Custom URL Scheme

:::android
Add the following to your `AndroidManifest.xml` file:

```xml
<activity android:name=".MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="exampleapp" />
    </intent-filter>
</activity>
```

This configuration allows your app to open in response to a deep link with the format `exampleapp://` from your `MainActivity` class.
:::

### Handling Deep Links

:::android
In your `MainActivity` (or the activity specified in your intent-filter), add the following Kotlin code to handle deep links:

```kotlin Kotlin
class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        // Respond to deep links
        respondToDeepLinks()
    }

    private fun respondToDeepLinks() {
        intent?.data?.let { uri ->
            Superwall.instance.handleDeepLink(uri)
        }
    }
}

```

### Handling App Links

## Adding app links

Android App links enable seamless integration between the Web checkout and your app,
enabling users to redeem the purchase automatically.

To allow Android app links to open your app, you will need to follow these steps:

## 1\. Add your app's fingerprint and schema to Stripe settings

To verify that the request to open the app is legitimate, Android requires your app's keystore SHA256 fingerprint, with at least one for your development keystore and one for your release keystore. You can obtain these fingerprints in the following way:

#### Development fingerprints

If you're using Android studio or have Android components installed, you can obtain your debug key by running the following command in your terminal:

`keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android`

And then copying the outputted SHA256 fingerprint.

#### Release fingerprints

To obtain the release fingerprints, you'll need your own keystore file (the one you use to sign the final application package before publishing).

You can do this by running the following command in your terminal:

`keytool -list -v -keystore <PATH_TO_YOUR_KEYSTORE> -alias <YOUR_KEY_ALIAS>`

And then copying the outputted SHA256 fingerprint.

#### Adding the fingerprints to the project

To add the fingerprints to Superwall, open the Settings tab of your Superwall Stripe application.
Under the `Android Configuration` title, you should see three fields:

* Package schema - this allows us to know which schema your app uses to open and parse deep links
* Package name - your app's package name, i.e. `com.mydomain.myapp`
* App fingerprints - One or more of your app's fingerprints, comma separated

![](https://json-ld-superwall-docs-staging.staffbar.workers.dev/docs/images/android-app-links-fingerprints.png)

Once added, click the `Update Configuration` button which will ensure the application asset links are properly generated for Google to verify.

### 2\. Add the schema to your app's Android Manifest

For this, you'll need to copy the domain from your Superwall Stripe settings.
Then, open your `AndroidManifest.xml`  and inside the `<activity ...>` tag declaring your deep link handling activity, add the following, replacing the domain with the one from the settings:

```xml
<intent-filter android:autoVerify="true">  
    <action android:name="android.intent.action.VIEW" />  
  
    <category android:name="android.intent.category.DEFAULT" />  
    <category android:name="android.intent.category.BROWSABLE" />  
  
    <data android:scheme="https" />  
	<data android:host="yourappdomain.superwall.app"
		  android:pathPrefix="/redeem" />  
</intent-filter>
```

### 3\. Handle incoming deep links using Superwall SDK

In the same activity as in step #2, you'll need to pass deeplinks along to Superwall SDK.
You can do this by overriding your Activity's `onCreate` and `onNewIntent` methods and passing along the intent data to Superwall using `Superwall.handleDeepLinks()` method. The method returns a `kotlin.Result` indicating if the deep link will be handled by Superwall SDK.

```kotlin
override fun onCreate(savedInstanceState: Bundle?) {  
    super.onCreate(savedInstanceState)
	// your onCreate code
	intent?.data?.let { uri ->  
	    Superwall.handleDeepLink(uri)  
	}
}

override fun onNewIntent(intent: Intent, caller: ComponentCaller) {  
    super.onNewIntent(intent, caller)  
    // ... Your onNewIntent code
    intent?.data?.let { uri ->  
	    Superwall.handleDeepLink(uri)  
	}
}
```

### 4\. Handling links while testing

If you are running your app using Android Studio, you need to be aware that it won't automatically allow verified links to be opened using the app, but you will need to enable it in settings yourself. This is not the case when installing from Play Store, and all the links will be handled automatically.

To do that, once you install the app on your device, open:
`Settings > Apps > Your Application Name > Open By Default`

Under there, the `Open supported links` should be enabled.
Tap `Add Links` button and selected the available links.

### Testing & more details

For details regarding testing and setup, you can refer to [Android's guide for verifying app links](https://developer.android.com/training/app-links/verify-android-applinks).
Note - Superwall generates the assetlinks.json for you. To check the file, you can use the subdomain from your Superwall stripe configuation:

`https://my-app.superwall.app/.well-known/assetlinks.json`

## Previewing Paywalls

Next, build and run your app on your phone.

Then, head to the Superwall Dashboard. Click on **Settings** from the Dashboard panel on the left, then select **General**:

![](https://json-ld-superwall-docs-staging.staffbar.workers.dev/docs/images/c252198-image.png)

With the **General** tab selected, type your custom URL scheme, without slashes, into the **Apple Custom URL Scheme** field:

![](https://json-ld-superwall-docs-staging.staffbar.workers.dev/docs/images/6b3f37e-image.png)

Next, open your paywall from the dashboard and click **Preview**. You'll see a QR code appear in a pop-up:

![](https://json-ld-superwall-docs-staging.staffbar.workers.dev/docs/images/2.png)

<br />

![](https://json-ld-superwall-docs-staging.staffbar.workers.dev/docs/images/3.png)

On your device, scan this QR code. You can do this via Apple's Camera app. This will take you to a paywall viewer within your app, where you can preview all your paywalls in different configurations.

## Using Deep Links to Present Paywalls

Deep links can also be used as a placement in a campaign to present paywalls. Simply add `deepLink_open` as an placement, and the URL parameters of the deep link can be used as parameters! You can also use custom placements for this purpose. [Read this doc](/docs/dashboard/guides/presenting-paywalls-from-one-another) for examples of both.
