# 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.

# Campaign Structure

Once you open a campaign, you can edit its details, placements, control experiments, view results, manage paywalls and more. The campaign detail screen is divided into three separate sections:

### Placements

Under the placements section, you can add, pause or delete existing placements. Placements are actions, or implicit events, which you can use to show a paywall or implement feature gating. Be liberal with adding placements, you can always pause them on-the-fly without app updates. Or, if you later decide to paywall a particular feature, it gives you more flexibility if you already have a placement for that particular action.

Learn more about placements [here](/docs/dashboard/dashboard-campaigns/campaigns-placements).

### Audiences

Audiences allow you to set up simple or complex filtering rules to match against certain users, show a particular paywall to them, view results of experiments and recent transactions resulting from them. All of your current audiences will show in the left-hand side of the campaign details screen.

Learn more about audiences [here](/docs/dashboard/dashboard-campaigns/campaigns-audience).

### Experiments

Audiences are also where you set up paywall experiments, and view their performance. Experiments allow you to show one or more paywalls, and see which one is "winning".

Learn more about experiments [here](/docs/dashboard/dashboard-campaigns/campaigns-starting-an-experiment).

### Renaming campaigns

To rename a campaign, click on the pencil icon next to the campaign's name, located in the top-left hand side of the campaign details screen:
