Horizon Boilerplate vs ShipFlutter

When choosing between Horizon Boilerplate 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 Horizon Boilerplate?

Horizon UI Boilerplate is a full‑stack / UI‑kit + boilerplate template for web applications built on modern front‑end and backend technologies. It is designed to help developers jump‑start a project (dashboard, SaaS app, admin panel, landing pages, etc.) without building all the plumbing and UI from scratch. Under the hood, it uses Next.js (recent version), along with React, and it supports styling with Tailwind CSS. It also integrates with Supabase for database/auth (or backend services) and Stripe for payment/billing handling providing a foundation for SaaS‑style apps with user authentication, subscriptions, payments, and user sessions. It supplies a large library of ready-made frontend building blocks: dashboards, admin layouts, landing pages, authentication screens, UI components (buttons, cards, navbars, form elements, etc.), and example page templates. This offers a starting point with both structural and visual parts already assembled. The boilerplate is offered in multiple variants: including a version built with Chakra UI or integration with shadcn/ui / Shadcn‑styled components or Tailwind, depending on your preference.

Developed by Vlad Mihalache, Horizon Boilerplate 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.
