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

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. Also available for React Native via expo-ondevice-ai. github.com/hyodotdev/loca… locanara.com medium.com/dooboolab/lang…

@belake195 I think I've managed to fix some of the issues earlier. Are you still experiencing this in `1.2.6`? github.com/hyochan/godot-…

@hyodotdev I'm encountering an issue with the Godot IAP. When I export the project to Xcode for debugging, the build fails with an error indicating that GodotIap.framework and SwiftGodotRuntime.framework are missing the Info.plist file. Godot 4.3 and Xcode 26.2. Could you help me plz? Tysm!

🎊 Happy New Year 2026! 🎮 In-App Purchase for Godot is now available! Official OpenIAP support for the Godot Engine is here. Starting from openiap v1.3.11, GDScript types are fully supported. • Native GDScript API • iOS & Android from one codebase • Type-safe generated bindings 📣 Announcement: #2025-12-31" target="_blank" rel="nofollow noopener">openiap.dev/docs/updates/a… 📚 Docs: hyochan.github.io/godot-iap @godotengine @godotfoundation @godotcon @DevGodot #GodotEngine #GameDev #IndieDev #OpenSource #MobileDev #InAppPurchase #OpenIAP

@arpit_bhayani Claude wants boss to take a rest

I was vibecoding and asked Claude to add a feature, and it legit (no kidding) cleaned up my database. I always thought such incidents were made up, but now that it has happened to me, I get it.

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!

@bidah @capsulethis So glad you found it useful — we put a lot of effort into making the API simple yet powerful. Would love to hear how it goes with your Capsule app! github.com/hyochan/expo-i…

ℹ️ Awesome Expo-compatible IAP library! by @hyodotdev. Perfect for seamless in-app purchases I am building my first app using @capsulethis and just discovered it. Feature set is very powerful: - Cross-Platform: Works flawlessly on iOS & Android with one API. Auto-handles platform quirks for consistent behavior. - TypeScript First: Full type safety, autocomplete, and compile-time error catching = smoother dev experience. - Error Resilience: Centralized handling + standardized error codes. No more platform-specific surprises. - Modern React Hooks: useIAP hook makes IAP integration clean and intuitive in function components. - Receipt Validation: Built-in secure validation for both stores. Edge cases? Handled automatically. - Up to Date :Always current with StoreKit 2, latest Billing Library, and new OS versions. Future-proof! Check it out link below 🧵👇

@priyankapudi @hailluek @priyankapudi Which in app purchase library are you using?

@hailluek yep I agree on that, but mobile dev makes things easier in app purchases easily trusted by the new users can implement the push notifications easily more secure and have to face apple rejections 1000 times before actually uploading to appstore 😅😂

Why no one is learning App devlopment ?

🚀 OpenIAP now officially supports Alternative Billing! After spending the last few weeks resolving some complex issues, this announcement came a bit later than planned — but good news: it’s already been featured in This Week in React! 🎉 Both react-native-iap and expo-iap now officially support Alternative Billing, fully powered by OpenIAP. 📱 Platform Notes On Android, the User Choice Billing mode lets you seamlessly combine in-app and third-party purchase flows within the same UI. In some regions (including South Korea), availability is still limited — please check your country’s policy. 💡 Why use Alternative Billing? Implementing unauthorized third-party payments may lead to App Store review rejections. Alternative Billing, on the other hand, follows Apple’s official guidelines for compliant third-party payment flows. The following OpenIAP-based SDKs are fully aligned with these guidelines: react-native-iap, expo-iap, flutter_inapp_purchase, and kmp-iap. 💸 Boost your revenue efficiency! By leveraging external purchase links, developers can reduce platform fees and improve overall profitability 📈 In Apple’s EU model, for example, commission rates can drop from up to 30% down to around 10–17% when using approved Alternative Billing options. 🔗 Learn more: OpenIAP → openiap.dev/docs/external-… React Native IAP → hyochan.github.io/react-native-i… Expo IAP → hyochan.github.io/expo-iap/docs/… Flutter IAP → hyochan.github.io/flutter_inapp_… Kotlin Multiplatform IAP → hyochan.github.io/kmp-iap/docs/g… #OpenIAP #AlternativeBilling #ReactNative #Expo #Flutter #KMP #InAppPurchases #DeveloperTools #Thisweekinreact
