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

OpenIAP now supports .NET MAUI 🚀 maui-iap v1.0.0 is now available as the official OpenIAP implementation for .NET MAUI. C# developers can now build in-app purchase flows across iOS, Android, and macCatalyst using the same OpenIAP model used across other platforms. Install: dotnet add package OpenIap.Maui --version 1.0.0 #OpenIAP #dotnet #CSharp #MAUI #InAppPurchases

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/open…

👉 Start building: kit.openiap.dev👉 Sponsor OpenIAP: openiap.dev/sponsors Free for every indie dev, forever. Sustained by the teams that depend on us. That's how developer tools should work.

🎉 IAPKit is joining OpenIAP and going 100% free — no paywall, no plans, no usage limits, no credit card. Receipt validation is the ground floor of in-app purchases. It shouldn't be a tier you pay for. kit.openiap.dev/blog/iapkit-jo…

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.

100%. Detection without recovery is half the job.We're keeping OpenIAP vendor-neutral, but planning a "recovery playbook" section in the docs with integration examples (SMS, push, email). Happy to include Signal House as one of them — DM if you'd like to collaborate on the SMS example.

Subscriptions silently failing is the #1 source of involuntary churn. Until now, catching it required a backend polling Apple/Google server notifications. We just shipped a single client-side event that fires on both iOS and Android when a user's payment fails. One listener. Zero backend infrastructure. Just detect the failure and deep-link the user to fix their card — done. Works across all 5 SDKs: React Native · Expo · Flutter · Godot · Kotlin Multiplatform #OpenIAP

Big OpenIAP update: All framework libraries are now moving into one monorepo. react-native-iap expo-iap flutter_inapp_purchase godot-iap kmp-iap One repo. One spec. One source of truth. This is now unified under OpenIAP Spec 2.0.0. No breaking changes. Same package names. Just update as usual. The goal is simple: When StoreKit 2, Google Play Billing, or OpenIAP types change, every framework can stay aligned from the same foundation. React Native, Expo, Flutter, Godot, and Kotlin Multiplatform should not each reinvent IAP separately. Individual repos will be archived this week. Links in the first reply.

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
