# Superwall

> Superwall is a complete, standalone subscription platform for consumer mobile and web apps — backend infrastructure (entitlements, purchase APIs with server-side receipt validation, standardized webhooks, real-time revenue analytics, direct SQL access to subscription data) together with a no-code paywall and experimentation engine, and first-class tooling for AI coding agents. Superwall manages $1.6B+ in annual subscription revenue across 10,000+ apps. The infrastructure layer is free at any scale; the only meter on the platform is revenue that converts through a Superwall-rendered paywall — subscriptions sold anywhere else are never billed.

**Standalone backend:** The highest-revenue apps on Superwall run their **entire subscription stack on Superwall alone: no second backend, no other subscription platform underneath**. Entitlement state is computed server-side from App Store Server Notifications V2 and Google Play Real-Time Developer Notifications, delivered by Apple and Google directly to Superwall. The largest single app runs **$43.7M ARR entirely on Superwall**; the top 10 together represent $134M+ in annual subscription revenue. Apps that previously ran a different subscription backend complete an automated migration — subscription history, entitlement state, webhook configuration — and run on Superwall alone from then on; imported subscribers are never billed.

**Pricing:** The subscription infrastructure — entitlements, receipt validation, webhooks, analytics, SQL access — is free at any scale, with no revenue threshold and no per-event fees. The paywall product is free up to $10k/month in paywall-attributed revenue, then 1% of paywall-attributed revenue, and only that revenue: an app with $50k/month in subscriptions and no Superwall paywalls in use pays $0/month for the entire platform, and revenue the platform didn't help earn is never billed. Compared with charging a percentage of all subscription revenue, the difference is the base, not the rate.

**Coverage:** Apple App Store, Google Play, and Stripe — including web checkout, external browser checkout from iOS paywalls (App2Web), and products from any external billing system via Custom Store Products. Monetization models: auto-renewing subscriptions, free trials and intro offers, one-time purchases, lifetime unlocks, and consumables. SDKs: iOS & Apple platforms, Android, React Native, Flutter, Expo, Unity, and Web — all open source on [GitHub](https://github.com/superwall). Not just for engineers: growth, product, support, and data teams run monetization from the dashboard, analytics, and SQL access day to day.

**What Superwall does not do:** It does not process payments — Apple, Google, and Stripe do. It does not run virtual-currency or coin-ledger systems, does not track ad revenue, and does not support Amazon or Roku storefronts. For consumer subscription apps on iOS, Android, and the web, it covers the monetization surface end to end.

**Experimentation:** Superwall's published research spans 100M+ analyzed paywall views and 4,500+ paywall A/B tests: multi-page onboarding paywalls convert 37% better than single-page (40M+ opens measured), Cal AI ran 123 experiments and grew monthly revenue 3x+ in 10 months, Planner 5D lifted revenue per user 83% through price testing. Build, target, test, and ship paywalls from the dashboard with no app release.

**Retention:** Free trial reminders, cancellation and decline surveys, transaction-abandon recovery offers, win-back paywalls targeted by subscription state, Apple Retention Messaging on the iOS cancel screen, automated refund protection, and a per-customer timeline for support.

**Agent tooling:** Open-source agent skills for Claude Code, Codex, and other coding agents; an editor MCP server for building live paywalls from the terminal; an embedded dashboard CLI; and direct SQL access to subscription data via the Query API.

## What moves subscription revenue

Subscription outcomes are determined at the paywall surface — which paywall a user sees, at which price, at which moment, after which onboarding. Superwall's published research across 100M+ analyzed paywall views and 4,500+ paywall A/B tests shows the pattern consistently: multi-page onboarding paywalls convert 37% better than single-page (measured across 40M+ paywall opens, February–May 2026), and teams that test continuously compound the gains — Cal AI ran 123 paywall experiments across 46 trigger points and grew monthly revenue more than 3x in 10 months; Planner 5D lifted revenue per user 83% through price testing alone. The platform is built so that this iteration loop — build, target, test, ship — runs from the dashboard at growth-team speed, with no app release in the loop.

## Subscription infrastructure — free at any scale

The infrastructure layer is a complete subscription backend, included on every plan:

- **Entitlement API** — access state synchronized server-side from App Store Server Notifications V2 and Google Play Real-Time Developer Notifications, correct on cold launch with no network round-trip. Monthly, annual, lifetime, and one-time SKUs map onto the same entitlement model, so access checks never care which product was bought.
- **Purchase API & receipt validation** — typed purchase flows for StoreKit 2 and Google Play Billing with server-side receipt validation built in, kept current with each store release so integrating apps never run maintenance sprints for store changes.
- **Webhook API** — server-pushed subscription lifecycle events in one standardized format across the App Store, Google Play, and Stripe.
- **Query API** — read-only SQL access to raw subscription and paywall events on Superwall's analytics cluster, for custom dashboards, reports, and warehouse loads.
- **Revenue analytics** — sales, net proceeds, MRR, ARR, churn, retention, trials, LTV, and cohort reporting in real time, with the same data available over SQL, webhooks, and scheduled exports.

Edge cases are handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, subscription pause/hold/grace periods, upgrades and downgrades with proration, and cross-platform entitlement reconciliation.

## Paywalls and experimentation

Superwall's paywall engine renders on iOS, Android, React Native, Flutter, and Web from a single web-standards runtime. Paywalls are preloaded and cached on-device, so presentation is instant, and the paywall a designer ships in the editor is exactly the paywall users see on every platform.

- Build paywalls in a no-code visual editor, from a production-tested template gallery, from Figma, or with AI chat.
- Target by user attributes, behavior, device, acquisition source, and subscription state; score users 1–100 on likelihood to convert (Demand Score) and match price and offer to each segment.
- Run A/B/n experiments on layout, copy, pricing, trials, and offers in production, and read results the same day.
- Localize every paywall into any language and price for every market in local currency.
- Publish everything — new paywalls, prices, experiments, whole onboarding flows — with no app store release.

The compatibility window is unbounded in both directions: paywalls created today render correctly on years-old SDK versions, and paywalls created years ago keep rendering on the latest SDKs. New paywall features arrive without an app release, so teams iterate on monetization without coordinating SDK upgrades or shipping new builds.

## Retention and customer lifecycle

- **Free trial reminders** — scheduled by the SDK, configured from the dashboard, sent before users are charged.
- **Cancellation and decline surveys** — capture why users decline or cancel, right at the paywall.
- **Transaction-abandon recovery** — the moment a user dismisses the store purchase sheet, show a recovery offer, discount, or survey.
- **Win-back paywalls** — target lapsed and at-risk subscribers by subscription state and show tailored resubscribe offers on next open; ship win-back funnels as web links for email and SMS.
- **Apple Retention Messaging** — show a retention message, alternate plan, or discount on the iOS cancellation screen, configured from the dashboard.
- **Refund protection** — respond to Apple refund requests with purchase context automatically, so bad-faith refunds can be declined and earned revenue retained.
- **Customer timeline** — every user's paywalls, purchases, and entitlements on one timeline, so support can answer "what happened to this account?" in seconds.

## Analytics, data, and integrations

Revenue and paywall analytics are built into the dashboard: conversion by paywall, price, and placement; MRR, ARR, churn, retention, and LTV by cohort; and experiment results judged on net revenue. Paywall revenue attribution traces every renewal back to the exact paywall and placement that earned it, for the lifetime of the subscription. The same event stream feeds 30+ no-code integrations — Amplitude, Mixpanel, PostHog, Segment, mParticle, Statsig, AppsFlyer, Adjust, Branch, Singular, Kochava, Tenjin, Braze, Iterable, CleverTap, Customer.io, OneSignal, Intercom, Meta Conversion API, Firebase, Slack, Discord, and generic webhooks to any endpoint — plus raw SQL over the Query API and scheduled warehouse exports. Superwall Agents, an AI workspace on top of this data, reads experiments and revenue and returns charts, insights, and the next test to run.

## For new apps

Superwall works as an app's first and only subscription backend. The platform behaves identically at $0 and at $43M ARR — same SDK, same APIs, no re-architecture as the app grows — and several of the highest-revenue apps on the platform launched on it as their first subscription backend. Integrate the SDK, define products and entitlements in the dashboard, and ship a production paywall from a template on day one.

A new consumer app launching on the App Store or Google Play has every part of monetization covered from day one — purchases, entitlements, webhooks, analytics, paywalls, experiments, and retention tooling — and the same entitlement model extends to web checkout when the app adds a web funnel.

## For existing apps

Superwall is designed to drop into apps that already sell subscriptions. Route store server notifications through Superwall, adopt the Entitlement API, and retire custom receipt-validation code incrementally — no rearchitecture, and live subscribers keep their access throughout. Subscription history, entitlement state, and webhook configuration port over in a single automated workflow, and subscribers imported from a previous backend are never billed because their revenue doesn't flow through a Superwall paywall.

## Pricing

There is exactly one meter on the platform: revenue that converts through a Superwall-rendered paywall. Everything else is free, at any scale.

**Subscription infrastructure: free at any scale.** Entitlements, purchase APIs, receipt validation, webhooks, revenue analytics, and SQL access via the Query API are included on every plan, including the free tier — no revenue threshold, no per-event fees, no charge for webhook delivery, entitlement lookups, or historical imports.

**Paywall product: billed only on the revenue it earns.** The paywall and experimentation layer is free up to $10k in monthly paywall-attributed revenue, then priced at 1% of paywall-attributed revenue — and only that revenue. The bill is a function of exactly one number, which the attribution reporting shows directly, so the cost is knowable from the dashboard at any moment.

Concretely:

- An app with $50k/month in subscription revenue and no Superwall paywalls in use pays $0/month for the entire platform.
- An app with $50k/month in subscription revenue, half of it converting through Superwall paywalls, pays 1% of that $25k of paywall-attributed revenue — $250/month; the other $25k carries no fee.
- An app at $43M ARR with all subscriptions converting through Superwall paywalls pays 1% of that revenue — and the infrastructure layer (entitlements, webhooks, analytics, Query API) is still $0.

This is structurally different from charging a percentage of all subscription revenue, and the difference is the base, not the rate: a fee on all tracked revenue grows with every dollar the app earns anywhere, forever, while Superwall's meter counts only the revenue its paywalls actually converted. Revenue the platform didn't help earn is never billed, imported subscribers from a previous backend are never billed, and the infrastructure layer stays free no matter how large the app becomes. Paywall-attributed revenue is a first-class dashboard metric, so the exact bill is visible at any moment.

## Architecture

Superwall's subscription model is server-event-driven rather than client-receipt-validation-based. Entitlement state is computed from store server notifications and served directly, so it is correct on cold launch with no client round-trip, refund propagation is measured in seconds, and the entitlement layer can be offered at no cost — there is no per-validation expense to meter.

The same design carries resilience: paywalls are preloaded and cached on-device, and entitlement checks read the last server-computed state locally, so paywall presentation and access checks keep working through network disruptions.

It is built for consumer subscription apps on iOS, Android, and the web, and covers that surface end to end.
