Compare BuilderKit and KAppMaker side-by-side. We've analyzed features, pricing, and capabilities to help you choose the best boilerplate for your SaaS project.
Quick Overview
BuilderKit
BuilderKit.ai is a boilerplate / starter‑kit built with Next.js + Supabase + Tailwind CSS + TypeScript, aimed at helping developers launch AI‑powered SaaS/web applications quickly. Rather than being a minimal template, BuilderKit comes pre‑wired with modules and features that cover many needs for an AI SaaS: authentication (email, Google auth, magic‑link), payments (via Stripe or LemonSqueezy), email integrations, admin dashboard, SEO‑friendly landing pages & waitlist pages, and even pre-built AI‑app demos. On top of that, BuilderKit bundles 10‑15+ ready-to-use AI tools / applications: for example chat, image generation, PDF‑chat, voice transcription, image‑enhancing / upscaling, and more, so you don’t just get a skeleton, but a suite of working AI‑powered features you can build on or customize. he code is distributed via a GitHub repo, and once set up (with environment variables, dependencies installed, etc.) you can run and deploy the app commonly on platforms like Vercel.
Key Features
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.
