# 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.

## Overview

To see the latest release, [check out the repository](https://github.com/superwall/Superwall-iOS).

You can install via [Swift Package Manager](#install-via-swift-package-manager) or [CocoaPods](#install-via-cocoapods).

## Install via Swift Package Manager

[Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the Swift compiler.

In **Xcode**, select **File ▸ Add Packages...**:

{" "}

**Then, paste the GitHub repository URL:**

```
https://github.com/superwall/Superwall-iOS
```

in the search bar. With the **Superwall-iOS** source selected, set the **Dependency Rule** to **Up to Next Major Version** with the lower bound set to **4.0.0**. Make sure your project name is selected in **Add to Project**. Then click **Add Package**:

## Install via CocoaPods

First, add the following to your Podfile:

`pod 'SuperwallKit', '< 5.0.0'
`

Next, run `pod repo update` to update your local spec repo. [Why?](https://stackoverflow.com/questions/43701352/what-exactly-does-pod-repo-update-do).

Finally, run `pod install` from your terminal. Note that in your target's **Build Settings -> User Script Sandboxing**, this value should be set to **No**.

### Updating to a New Release

To update to a new beta release, you'll need to update the version specified in the Podfile and then run `pod install` again.

### Import SuperwallKit

You should now be able to `import SuperwallKit`:

## Tab

```swift Swift
import SuperwallKit
```

## Tab

```swift Objective-C
@import SuperwallKit;
```
