As answered by people managing CodePen and KAppMaker.
KAppMaker's answer:
KAppMaker is special because it combines everything you need to build apps for both iOS and Android in one place. It has ready-made features that save time and make development easier.
KAppMaker's answer:
People should choose KAppMaker because it helps them get started quickly with built-in tools like authentication, in-app purchases, notifications and more. Also it is updated regularly so developers should not worry about necessary workarounds, or fixes.
KAppMaker's answer:
Our main audience includes indie developers and small startups who want to build mobile apps fast. They are looking for a way to create high-quality apps without spending too much time on setup.
KAppMaker's answer:
We use Kotlin Multiplatform and Compose Multiplatform as the main technologies for KAppMaker for both shared code and UI. Additionally, we use tools like GitHub Actions for deployment and Firebase for authentication and push notifications along with KMPAuth and KMPNotifier libraries. For in-app purchases and subscriptions RevenueCat is used. And for making dependency injection easy we used Koin.
KAppMaker's answer:
KAppMaker was born from the frustration of developers who spend too much time on setup, which slows them down and prevents them from publishing their apps. We wanted to create a solution that allows developers to focus solely on the features they want to offer users, making the app-building process faster and more efficient.
KAppMaker's answer:
Our biggest customers are indie developers and small businesses looking to launch their apps quickly.
