KAppMaker vs ShipFlutter

When choosing between KAppMaker and ShipFlutter, it's essential to understand the key differences that make each boilerplate unique. Both are excellent choices for building SaaS applications, but they cater to different needs and development approaches.

What is KAppMaker?

KAppMaker is a cross-platform mobile app boilerplate built on Kotlin Multiplatform and Compose Multiplatform, designed to provide a single codebase for creating native Android and iOS applications. It delivers a structured foundation with pre-wired user authentication, subscription and in-app purchase support, push notifications, local data storage, and UI navigation scaffolding. The boilerplate integrates modern development tools such as Ktor for network requests and dependency injection, along with a shared project structure that enables rapid screen creation, code reuse, and deployment across platforms. By offering a ready-to-use architecture, KAppMaker reduces the initial setup and wiring of core app functionality, while still allowing developers to extend or customize the codebase. Its focus on Kotlin Multiplatform makes it suitable for developers or small teams aiming to launch production-ready mobile applications efficiently without duplicating work for Android and iOS.

Developed by Mirzamehdi Karimov, KAppMaker has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

What is ShipFlutter?

ShipFlutter is a cross‑platform starter kit built on Flutter (with Dart), intended to help developers ship Android, iOS and web apps from a single codebase without starting from scratch. It combines frontend UI, backend setup, and common infrastructure so you can launch mobile + web apps faster. ShipFlutter delivers a fully customizable app scaffold including: authentication (email/password, social login, anonymous auth), responsive cross‑platform UI with theming and localization, navigation via GoRouter, state management via Signals, and Material styling. On the backend it offers integration with Firebase (Firestore, Functions, hosting, realtime updates) and optional AI/ML capabilities via Vertex AI useful if you plan AI‑powered features. For monetization or SaaS‑style apps, it supports payments: mobile IAP/subscriptions via RevenueCat and web payments via Lemon Squeezy. It also includes support for notifications, analytics/monitoring, feedback, offline‑ready data handling, and optional templates (for example UI templates, landing‑page/marketing‑page templates, even Tinder‑style or chatbot‑style UIs) enabling you to ship full‑featured apps quickly.

When building a SaaS application, choosing the right payment integration is crucial for monetization success. Let's compare the payment options available in KAppMaker and ShipFlutter.

Neither boilerplate includes pre-built payment integrations. You'll need to implement your preferred payment solution manually. Consider using Stripe, Lemon Squeezy, or Paddle for your SaaS monetization.

Both KAppMaker and ShipFlutter are excellent choices for building SaaS applications. Your decision should be based on your specific requirements, budget, and technical preferences.

KAppMaker is ideal if you're looking for a more affordable option with specific capabilities.

ShipFlutter stands out for its comprehensive feature set and is perfect for developers who need specific features.

Ultimately, both boilerplates will help you launch your SaaS product faster and more efficiently. Review the detailed comparison above, consider your project requirements, and choose the one that aligns best with your goals.
