# 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).

# Migrating from React Native SDK

Guide to migrating from the legacy React Native SDK

This guide is for React Native projects that already have Superwall's legacy React Native SDK installed and want to migrate to the new Expo SDK.

> **Note:** **This doesn't sound like you?**- **Expo project** → Use the standard [installation guide](/docs/expo/quickstart/install)
> - **React Native app, new to Superwall** → See our [installation guide for bare React Native apps](/docs/expo/guides/using-expo-sdk-in-bare-react-native)

> **Warning:** **Important: Expo SDK 53+ Required**This SDK is exclusively compatible with Expo SDK version 53 and newer. For projects using older Expo versions, please use our [legacy React Native SDK](https://github.com/superwall/react-native-superwall).

This guide is to help you migrate your project using the legacy `react-native-superwall` SDK to the new Expo SDK. The `expo-superwall/compat` SDK is intended to make it easy for existing projects to migrate over.

## Installation

First, you need to install `expo-superwall` using your package manager of choice.

## Tab

```bash bun
bunx expo install expo-superwall
```

## Tab

```bash pnpm
pnpm dlx expo install expo-superwall
```

## Tab

```bash npm
npx expo install expo-superwall
```

## Tab

```bash yarn
yarn dlx expo install expo-superwall
```

## Basic Setup

Configure the SDK with your **Public API Key**. You'll retrieve this from the Superwall settings page, same as your existing React Native project.

```tsx
import Superwall from "expo-superwall/compat"
import { useEffect, useState } from "react"
import { Platform } from "react-native"

// Initialize Superwall
useEffect(()=> {
	const apiKey = Platform.OS === "ios"
        ? "yourSuperwall_iOSKey"
        : "yourSuperwall_androidKey";
	Superwall.configure({ // `await` is optional here if not chaining or needing immediate confirmation
		apiKey,
	});
})
```

## Identify User

```tsx
// Identify a user
await Superwall.shared.identify({ userId })

// Set User Attributes
await Superwall.shared.setUserAttributes({
        someCustomVal: "abc",
        platform: Platform.OS,
        timestamp: new Date().toISOString(),
})
```

## Present a Paywall

```tsx
// Present a paywall
Superwall.shared.register({
      placement: "yourPlacementName",
      feature() {
        console.log(`Feature called!`)
      },
})
```

## Listen to Events

```tsx
// 1. Define your Superwall Delegate
import {
  EventType,
  type PaywallInfo,
  type RedemptionResult,
  type SubscriptionStatus,
  SuperwallDelegate,
  type SuperwallEventInfo,
} from "expo-superwall/compat"

export class MyDelegate extends SuperwallDelegate {
  handleSuperwallEvent(eventInfo) {
    switch (eventInfo.event.type) {
      case EventType.paywallOpen:
        console.log("Paywall opened");
        break;
      case EventType.paywallClose:
        console.log("Paywall closed");
        break;
    }
  }
}

// 2. Simply set the delegate
const delegate = new MyDelegate()
await Superwall.shared.setDelegate(delegate)

```
