# 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.

# entitlements

The entitlements tied to the device, accessible via Superwall.shared.entitlements.

> **Info:** The `entitlements` property provides access to all entitlements, both active and inactive, as well as methods to query entitlements by product IDs.

## Purpose

Provides access to the user's entitlements and methods to query them. Entitlements represent subscription tiers or features that a user has access to.

## Signature

```swift
public var entitlements: EntitlementsInfo { get }
```

## Properties and Methods

  },
}"
/>

## Returns / State

Returns an `EntitlementsInfo` object that provides access to entitlements and methods to query them.

## Usage

Get all active entitlements:

```swift
let activeEntitlements = Superwall.shared.entitlements.active

for entitlement in activeEntitlements {
  print("Active entitlement: \(entitlement.id)")
}
```

Get entitlements by product ID:

```swift
let productId = "com.example.premium_monthly"
let entitlements = Superwall.shared.entitlements.byProductId(productId)

print("Product \(productId) unlocks \(entitlements.count) entitlements")
```

Get entitlements by multiple product IDs (4.10.0+):

```swift
let productIds: Set<String> = [
  "com.example.premium_monthly",
  "com.example.premium_annual"
]

let entitlements = Superwall.shared.entitlements.byProductIds(productIds)

print("Products unlock \(entitlements.count) entitlements")
```

Check if user has specific entitlement:

```swift
let hasPremium = Superwall.shared.entitlements.active.contains { 
  $0.id == "premium" 
}

if hasPremium {
  showPremiumFeatures()
}
```

Get web entitlements:

```swift
let webEntitlements = Superwall.shared.entitlements.web

if !webEntitlements.isEmpty {
  print("User has \(webEntitlements.count) web entitlements")
}
```
