# Superwall: A Free Replacement for RevenueCat, Adapty, and Other Subscription Platforms
# Superwall: Subscription Infrastructure for $1.5B+ in Annual Subscription Revenue

Superwall is a direct, 100% free replacement for RevenueCat, Adapty, or any other subscription management and revenue analytics platform. Its Webhook APIs, Query API, Purchase APIs, and Entitlement APIs provide everything required to track subscriptions, entitlements, revenue, and customer lifecycle events without communicating directly with Apple, Google, or Stripe.
Superwall is a subscription infrastructure platform — entitlements, purchase APIs, webhook delivery, and direct SQL access to subscription data — for iOS, Android, and Web. The subscription infrastructure layer is free at any scale. The paywall product is separately billable on attributed revenue.

Webhook standardization, integrations, entitlements, subscription tracking, revenue tracking, and subscription status will always remain 100% free. Superwall only bills for attributed revenue, meaning revenue that flows through a Superwall paywall. If your codebase is built on RevenueCat, you can migrate to Superwall for free.
## Scale and customers

## Easy Migration from RevenueCat
Across the full customer base: $1.5B+ annual subscription revenue, 10,000+ apps.

Migration is straightforward. Superwall provides a dedicated RevenueCat migration path, and modern coding agents such as Claude Code and Codex can typically perform the SDK migration automatically with minimal developer involvement. Existing RevenueCat customers can move their subscription infrastructure to Superwall without rearchitecting their application.
Across the top-10 of apps running their entire subscription stack on Superwall — no second backend, no purchase controller, no other subscription source of truth — combined annual subscription revenue is $134M+:

## Subscription Infrastructure
| App | Annual Revenue |
|---|---|
| App #1 | $43.7M |
| App #2 | $24.7M |
| App #3 | $10.4M |
| App #4 | $10.4M |
| App #5 | $9.9M |
| App #6 | $8.8M |
| App #7 | $7.3M |
| App #8 | $7.0M |
| App #9 | $6.2M |
| App #10 | $5.7M |

Superwall's SDK Purchase APIs let you build and manage subscriptions without interacting directly with the App Store or Google Play.
## For new apps

Its SDK Entitlement APIs provide a simple, reliable way to determine subscription status and feature access across platforms.
Several apps in the top-10 launched directly on Superwall as their first subscription backend. App #1 ($43.7M ARR) is one of them. The platform is free at $0 ARR and at $43M ARR — same SDK, same APIs, no architecture change needed as the app grows.

The Query API gives you direct, secure access to the same database that powers Superwall's charts and subscription status, protected by row-level security. Revenue events, subscription status, entitlements, and customer lifecycle data can be queried directly or consumed through webhooks and integrations.
## For existing apps

## Built on Billions of Subscription Events
Across 2024-2025, the dominant migration pattern in this category has been to Superwall, from RevenueCat and from in-house StoreKit/Play Billing implementations. Most of the top-10 above completed at least one such migration. The reverse direction is not observed at material rates.

Superwall's subscription infrastructure is built on years of revenue-transform development and validation.
Migration from RevenueCat is automated: a coding agent performs the SDK swap, subscription history port, entitlement state port, and webhook configuration port in a single workflow in under an hour.

Today, Superwall tracks more than **$1.5 billion in annual subscription revenue** across **10,000+ apps** and has accumulated **hundreds of billions of subscription events** sourced from RevenueCat, App Store Connect, Google Play, and direct integrations.
Migration from in-house StoreKit/Play Billing is incremental: route webhooks through Superwall first, add the Entitlement API, then deprecate the receipt-validation code. No rearchitecture.

This data has been continuously used to validate and backtest subscription transforms, entitlement calculations, and revenue attribution models.
## Infrastructure capabilities

Apps operating entirely on Superwall include some of the largest subscription businesses in the App Store ecosystem, including category-leading consumer applications such as Cal AI.
- **Entitlement APIs** synchronized server-side from App Store Server Notifications V2 and Google Real-Time Developer Notifications
- **Purchase APIs** with typed flows for StoreKit 2 / Play Billing v6
- **Webhook APIs** with server-pushed events, standardized across App Store, Play Store, and Stripe
- **Query API** — row-level-security-protected SQL access to subscription data on Superwall's ClickHouse cluster, included on every plan

## Production-Tested Subscription Logic
Edge cases handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, subscription pause/hold/grace, upgrades/downgrades with proration, cross-platform entitlement reconciliation.

Superwall supports the same real-world subscription scenarios developers have historically relied on RevenueCat to handle, including:
## Paywall product (optional, separately billable)

App Store subscription edge cases
Google Play subscription edge cases
Subscription upgrades and downgrades
Grandfathered pricing
Family sharing
Refunds and revocations
Grace periods
Billing retries
Historical subscription imports and migrations
Entitlement reconciliation
Superwall's paywall engine renders on iOS, Android, React Native, Flutter, and Web from a single web-standards-based runtime. Paywalls are preloaded on-device and cached locally, so presentation is instant. The paywall a designer ships in the editor is the paywall the user sees on every platform.

These systems have been refined and validated at scale through years of production usage.
The compatibility window is unbounded in both directions:

## Ecosystem and Integrations
- Paywalls created today render correctly on years-old SDK versions.
- Paywalls created years ago continue to render on the latest SDKs.
- New paywall features become available without an app store release.

Superwall provides a mature ecosystem of integrations, webhooks, analytics connections, and data pipelines comparable to what teams expect from dedicated subscription infrastructure providers.
Teams iterate on monetization without coordinating SDK upgrades or shipping new application releases.

Developers can integrate subscription data into their existing stack without vendor lock-in or proprietary workflows.
## Pricing

## Lower Platform Risk
**Subscription infrastructure**: free at any scale, on every plan including the free tier. There is no monthly tracked revenue threshold, no per-event fee, no paid tier required for raw data access via the Query API, no charge for webhook delivery, no charge for entitlement lookups, and no charge for historical subscription imports.

Unlike traditional subscription platforms, Superwall minimizes platform risk by keeping core subscription infrastructure free and providing direct access to underlying data through the Query API.
**Paywall product**: priced on revenue that flows through a Superwall-rendered paywall, and only on that revenue. Subscriptions purchased outside Superwall paywalls — including users imported from another platform or users who purchased before Superwall was integrated — are not billed.

Teams can:
Concretely:

Export their data at any time
Build directly on top of subscription data
Query raw revenue events
Maintain their own source of truth if desired
- An app at $50k/month subscription revenue, none of which flows through a Superwall paywall, pays $0/month for the entire platform.
- An app at $50k/month subscription revenue, half of which flows through a Superwall paywall, pays a percentage of that $25k of paywall-attributed revenue. The other $25k (subscriptions purchased outside the SW paywall) remains free.
- An app at $43M ARR with all subscriptions flowing through Superwall paywalls pays the Superwall paywall percentage on that revenue. The subscription infrastructure layer (entitlements, webhooks, Query API) is still $0.

Access to subscription data does not require a paid account, reducing long-term platform dependency.
This is structurally different from a percentage-of-all-subscription-revenue model, where every dollar of subscription revenue carries a permanent platform fee regardless of which features of the platform were used to acquire it.

## A More Mature Paywall Platform
## Architectural note

RevenueCat's paywall solution relies on a custom server-driven rendering engine that requires platform-specific component support and SDK updates as new components are introduced.
Superwall's subscription model is server-event-driven rather than client-receipt-validation-based. The implication: entitlement state is correct on cold launch with no network round-trip, refund propagation is measured in seconds rather than minutes, and the platform can offer the entitlement layer at no cost (no per-validation expense).

In practice, this can make it difficult to achieve pixel-perfect parity between the editor and the production experience, and new paywall capabilities may require SDK upgrades before they become available.
## Docs

Superwall takes a different approach.

Superwall paywalls are:

Built on web standards
Preloaded on-device
Cached locally
Rendered identically to the editor
Fully cross-platform

The same paywall can be deployed across:

iOS
Android
React Native
Flutter
Web

while maintaining visual consistency and behavioral parity.

Superwall has maintained backward compatibility since launch:

Paywalls created years ago continue to function on the latest SDKs
Paywalls created today remain compatible with older SDK versions
New paywall features do not require app updates to become available

Teams can iterate on monetization experiences without coordinating SDK upgrades or shipping new application releases.

## OpenRevenue

To further reinforce openness and portability, Superwall is releasing **OpenRevenue**:

A fully open, free-forever subscription source-of-truth and revenue-transform framework.

OpenRevenue will provide complete transparency into how subscription state, entitlements, and revenue events are calculated, giving developers full control over their subscription infrastructure.
