Achromatic vs ShipFlutter

When choosing between Achromatic 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 Achromatic?

Achromatic is a Next.js 15–based SaaS starter that tries to cover most of the groundwork developers usually build themselves: authentication, organizations, role management, billing, email, and a consistent UI built on shadcn/ui and Tailwind. The appeal is that it doesn’t just drop in loose components — the pieces are wired together in a way that feels closer to a real application than a template. The onboarding flow, subscription logic, and organization system actually work out of the box, which makes it easy to jump into feature development without spending days on the usual boilerplate chores. There are a few things worth noting, though. The project is relatively new, and the ecosystem around it is still small, so you’re buying into a structure that depends heavily on the maintainer’s ongoing involvement. It’s an opinionated setup, which is great if you like the architecture as-is, but less ideal if you prefer a lighter, more minimal foundation. Achromatic positions itself as a time-saver for developers who want a polished starting point rather than assembling every piece manually, and it mostly succeeds at that. Still, it’s best suited for teams comfortable adopting someone else’s patterns and conventions anyone needing maximum flexibility might find it a bit heavier than they’d like.

Developed by Mahmut Jomaa, Achromatic 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.
