Introducing Crosspay: The Future of Cross-Platform Monetization

Today marks a major milestone for the app development community. We're incredibly excited to introduce Crosspay, the first truly unified monetization SDK designed for the modern cross-platform era.

For the past year, we have been working stealthily with a mix of indie developers and enterprise teams to solve one of the most painful aspects of software development: getting paid.

The Fragmentation Problem

If you are building a modern app, you are likely using a cross-platform framework like React Native, Flutter, or Tauri. You write your UI code once, and it runs beautifully on iOS, Android, web, and desktop.

But the moment you try to implement a "Pro" subscription, that cross-platform dream shatters.

• On iOS, you wrestle with StoreKit 2, App Store Connect configuration, and Apple's strict review guidelines.
• On Android, you deal with the Google Play Billing Library, AIDL restrictions, and a completely different set of receipt validation logic.
• On the Web & Desktop, you are on your own, stitching together Stripe components and managing VAT/GST compliance manually.

This fragmentation forces teams to build three separate billing stacks. It diverts engineering resources away from your core product and creates a maintenance nightmare.

Enter Crosspay

Crosspay simplifies everything. We believe that if your business logic is cross-platform, your revenue logic should be too.

With a single integration, you gain access to:

1. A Unified API

Forget SKPaymentQueue and BillingClient. With Crosspay, you write one line of code to trigger a purchase on any device:

await Crosspay.purchase('pro_yearly');

We handle the underlying platform intricacies, ensuring you always use the latest APIs (StoreKit 2, Billing Library 6) without needing to update your code.

2. Server-Side Receipt Validation

Never trust the client. Crosspay instantly validates every transaction on our secure server infrastructure. We handle retries, duplicate detection, and fraud prevention, giving you a clean "source of truth" for user entitlements.

3. Real-Time Entitlements

Subscriptions lapse. Credit cards fail. Users request refunds. Crosspay manages the entire lifecycle of a subscription. When a user checks their status:

if (await Crosspay.hasEntitlement('pro_access')) {
  // Grant access
}

We ensure this check is accurate to the millisecond, across all their devices.

4. Remote Paywalls

Iteration is the key to growth. Our Remote Paywall engine allows your marketing team to update prices, copy, and images in real-time without submitting a new build to the App Store. A/B test your pricing models to find what maximizes revenue.

Built for the Future

Our mission is to help developers focus on building great products, while we handle the complexity of global payments and compliance. Whether you are a solo indie hacker or a Fortune 500 enterprise, Crosspay scales with you.

We are just getting started. Join us on this journey.
