# 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.

# Install the SDK

Install the Superwall Unity SDK beta through Unity Package Manager.

## Overview

Install the Unity SDK from the [Superwall-Unity GitHub repository](https://github.com/superwall/Superwall-Unity). The beta package name is `com.superwall.sdk`.

## Requirements

* Unity 6+ (`6000.4+`)
* iOS 16.0+
* Android `minSdkVersion` 25+
* CocoaPods installed locally for iOS builds

## Add the Package

In Unity, open **Window > Package Manager**. Click **+**, choose **Add package from git URL**, then paste:

```text
https://github.com/superwall/Superwall-Unity.git
```

![Unity Package Manager Add package from git URL](https://claude-centralize-agent-preamble-superwall-docs.staffbar.workers.dev/docs/images/upm_add.jpg)

After Unity resolves the package, your scripts can import the SDK:

```csharp C#
using Superwall;
```

## iOS Build Setup

The package includes an iOS post-build processor. When you build for iOS, it:

1. Creates a `Podfile` if the generated Xcode project does not have one.
2. Adds `pod 'SuperwallKit', '~> 4.0'` to the `UnityFramework` target.
3. Sets the iOS deployment target to `16.0`.
4. Runs `pod install` in the generated Xcode project directory.

If `pod install` fails, run it manually in the generated Xcode project folder and reopen the `.xcworkspace`.

> **Note:** If your Unity project already customizes the generated `Podfile`, make sure the `UnityFramework`
> target includes the `SuperwallKit` pod.

## Android Build Setup

No manual Android SDK setup is required for the default Unity Gradle export. The package includes a
Gradle `.androidlib` module that declares the Superwall paywall activities and pulls:

* `com.superwall.sdk:superwall-android:2.+`
* Google Play Billing `8.0.0`
* Material Components `1.12.0`
* Kotlin coroutines for Android `1.9.0`

The included Android manifest adds the internet, network state, notification, and Google Play Billing permissions, plus the Superwall paywall and debug activities.

> **Warning:** If your project uses custom Gradle templates, keep `google()` and `mavenCentral()` enabled and do
> not remove the generated Superwall `.androidlib` dependency.
