ShipFlutter vs Supaboost

When choosing between ShipFlutter and Supaboost, 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 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.

Developed by Marcel, ShipFlutter has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

What is Supaboost?

Supaboost is a full‑stack SaaS starter kit built on Next.js (version 14) and Supabase designed to accelerate building web apps, marketplaces or SaaS products by providing a ready‑to‑use foundation. Out of the box, Supaboost includes: secure user authentication and role‑based user/organization management, a working PostgreSQL‑based database schema (with row‑level security), subscription and payment integration via LemonSqueezy for subscriptions and transactions, and a clean, maintainable codebase using TypeScript + modern UI built with Shadcn UI. On top of backend & auth/payment plumbing it provides basic UI scaffolding, data‑visualization tools (using e.g. Recharts), form management support (via TanStack Forms) and integrations helpful for building SaaS‑style features quickly. On the trade‑off side: adopting Supaboost means committing to its stac: Next.js + Supabase + LemonSqueezy + the provided UI/layout + conventions. If your project requires a radically different backend, non‑SQL database, or custom payment flow, you may need to rework significant parts. Also, while it offers many integrations, relying heavily on the boilerplate may mean inheriting its assumptions (schema, auth structure, payment model), which might not fit all projects. Finally like any “all-in-one” starter, the feature richness may be overkill for very simple apps or prototypes.
