# 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.

# Framework Documentation

Superwall is a platform for remotely configuring and A/B testing mobile app paywalls — no app update required. It provides SDKs for iOS, Android, Flutter, Expo, KMP, Unity, Web, and React Native, plus a dashboard for managing paywall presentation, experiments, and subscription analytics.

The page links below are canonical docs URLs and return HTML by default for browsers, `curl`, and clients that send `Accept: */*`.

To fetch a page as markdown, either send `Accept: text/markdown` for the canonical URL or append `.md` to the route, for example:

- https://superwall.com/docs/framework/quickstart.md

When using `Accept: text/markdown`, doc URLs return a 307 redirect to the `.md` route. Always use `curl -sL` (follow redirects) when fetching them.

- [Actions](/docs/framework/actions): Close the paywall, restore purchases, open links, request OS permissions, and call back into your app, everything a paywall asks its host to do.
- [Assets](/docs/framework/assets): Add images, video, audio, fonts, and animations to a paywall by importing files. The build handles optimization, hosting, and caching.
- [Build Paywalls with an AI Agent](/docs/framework/build-with-an-agent): Describe a paywall in plain English and let an AI agent build it, preview it in the studio, and ship it to Superwall. No commands to type.
- [CLI Reference](/docs/framework/cli): Every superwall command (create, dev, push, promote, publish) with flags, auth, and the checks that run before anything ships.
- [Configuration](/docs/framework/config): Everything definePaywall accepts, products, background, transitions, trial reminders, and the behavior settings that shape a paywall.
- [Examples](/docs/framework/examples): Complete, standalone example projects, each teaching exactly one idea, from a minimal paywall to trials, funnels, and Rive animations.
- [Hooks Reference](/docs/framework/hooks): Every hook the framework provides, signatures, what each returns, and the semantics that matter.
- [Host Protocol](/docs/framework/host-protocol): The messages a paywall exchanges with whoever is showing it — the SDK on a device, the studio locally, the dashboard in a browser — and what each side promises.
- [Superwall Framework](/docs/framework): Build paywalls, onboarding funnels, and web checkout flows as React mini-apps, in your repo, with your tools, shipped without an app update.
- [Lifecycle & Events](/docs/framework/lifecycle): What a paywall knows and when, the preload rule that shapes every entry animation, and the SDK events you can react to.

- [Migrating from the editor](/docs/framework/migrate-from-editor): Rebuild a paywall made in Superwall's visual editor as a framework paywall: what the CLI scaffolds, what an agent rebuilds, how you review it against the original, and how the switch happens.
- [Migrating native screens](/docs/framework/migrate-native-screens): Turn a SwiftUI, UIKit, Jetpack Compose, Android Views, React Native or Flutter screen into a Superwall surface the app can change without a release: what the CLI reads from the source, what an agent rebuilds, how you review it against a simulator screenshot, and how the app is wired afterwards.
- [Pages & Navigation](/docs/framework/navigation): Build multi-page paywalls, onboardings, and funnels with file-based pages and a stack router, no network between steps, no loading spinners.
- [Products](/docs/framework/products): Declare product slots in config.ts, read live store data through useProducts, and follow the three rules that keep prices honest.

- [Purchases](/docs/framework/purchases): Make the sale with usePurchase, handle completed, abandoned, and failed outcomes, restore purchases, and react to transactions from anywhere.
- [Push, Promote & Publish](/docs/framework/push-and-promote): Ship paywalls with git semantics: push seals an immutable version, promote points production at it, publish does both.
- [Quickstart](/docs/framework/quickstart): Scaffold a Superwall Framework project, preview your first paywall in the studio, and ship it to production.
- [The Studio](/docs/framework/studio): Preview every paywall locally with superwall dev: devices, themes, locales, live variables, and purchase, restore, permission and callback outcomes you choose.
- [Styling](/docs/framework/styling): How styling works in a paywall, plain CSS, the color-scheme class, the background color, insets and safe areas, and the platform stylesheet Superwall applies at serve time.

- [Troubleshooting](/docs/framework/troubleshooting): Common CLI errors and runtime surprises, what each one means and how to fix it.
- [Variables & Personalization](/docs/framework/variables): React to user attributes, device state, and placement parameters, and write paywalls the dashboard can experiment on without a rebuild.
