Our open sources are now backed by Meta! 🎉 On Korea’s Liberation Day, I’m excited to share — Meta is now sponsoring our in-app purchase libraries, from React Native IAP to Expo IAP. This unexpected support means a lot and feels like recognition for 8 years of dedication to IAP solutions. I’m working on new ways to make IAP even more accessible and reliable for developers. Stay tuned — exciting things are coming! #opensource #reactnative #expo #inapppurchase #iap #mobiledevelopment #Meta #sponsorship #thankyou #facebook

Apple JWS. Google Play Developer API. Refund webhooks. Replay attacks. If you've shipped IAP, you've rewritten this. Today I'm open-sourcing the SaaS I built a few months ago to make this go away. IAPKit joins the OpenIAP monorepo — 5 client SDKs, 1 server, 1 GraphQL schema. cc @AdamGerthel 🙏 kit.openiap.dev github.com/hyodotdev/openiap

What's changing: All validation APIs: free forever Same access for indie projects and production apps — everyone pays $0 Existing paying customers fully refunded Sustained by OpenIAP Sponsorship ($25–$1,000 tiers via PayPal / GitHub Sponsors) Following the path Redis, PostgreSQL, Sentry walked.

Locanara is now open source — an on-device AI framework for iOS & Android. LangChain for mobile, fully local. Composable chains, memory, guardrails, pipeline DSL. Same API across platforms. No cloud.

Messages like this are why I care so much about open source.

OpenIAP has officially partnered with Gotterdammerung AB, a European game studio, to launch the new In-App Purchase Verification Service — designed to solve one of the biggest pain points for developers using IAP libraries: purchase verification. lnkd.in/gQJ29yhn We’re starting with a minimal, clean implementation — offered at about 5× lower cost than existing solutions. From here, we plan to expand steadily so developers no longer have to worry about verification complexity at all. 🔐 Purchase verification, now a single API call With just your IAPKit key and one call to `verifyPurchaseWithProvider()`, IAPKit takes care of all the previously complex, platform-specific logic — securely, consistently, and fully unified. 📦 Available today across OpenIAP core and third-party libraries lnkd.in/gPNc2xwG Expo IAP: lnkd.in/gBRpSBxK React Native IAP: lnkd.in/gtPXVMpi Flutter IAP: lnkd.in/gNF3cEtK KMP IAP: lnkd.in/gp3n74vu 🌐 Learn more iapkit.com With this launch, OpenIAP will continue to explore and build new capabilities to make the entire IAP ecosystem richer and more developer-friendly. #OpenIAP #IAPKit #InAppPurchase #OSS #IAP

Sharing a visualized diagram of the OpenIAP ecosystem. It shows how the native IAP core (Apple/Google/Horizon) works together with the GraphQL type-generation layer and the client SDKs used in third-party libraries like React Native, Expo, Flutter, and Kotlin Multiplatform.

We built a new styling library specifically for React Native! We love styled-components, but the runtime overhead always bothered us. So we made "kstyled" - it compiles styles at build time using Babel, giving you zero runtime cost while keeping the familiar API. Key highlights: ✅ Zero runtime overhead (compiles to StyleSheet.create) ✅ Same syntax as styled-components ✅ Smaller bundle (~10KB vs 13-21KB) ✅ 8-15% faster rendering (more for complex components) ✅ Full TypeScript support ⚠️ Note: kstyled is still in beta, so there might be some edge cases left to iron out. I’ve been using it in my own apps and have been really happy with the performance so far! Quick example: ```tsx import { styled } from 'kstyled'; const Button = styled.Pressable<{ $primary?: boolean }>` padding: 16px 32px; border-radius: 8px; background-color: ${p => p.$primary ? '#007AFF' : '#ccc'}; `; ``` If you're already using styled-components or emotion, migration is super easy!
