Achromatic vs ApparenceKit

When choosing between Achromatic and ApparenceKit, 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 ApparenceKit?

ApparenceKit is a template generator for Flutter, created by a team with years of Flutter-app experience. On the surface, it’s pitched as a way to bypass many of the repetitive, boilerplate tasks that come with building a mobile (or web) app from scratch: authentication, user flows, payments/subscriptions, push notifications, onboarding, i18n (multilanguage), analytics, theming, and more. When you use ApparenceKit, you start your project by running a CLI that scaffolds a full Flutter app wired up with a backend option (you can choose between Firebase, Supabase or a custom REST API), pre-built modules for auth, subscriptions, notifications, and navigation, plus optional modules such as feedback/voting, translations, remote config, and more. This means that instead of spending weeks setting up the basics of your app (login logic, paywalls, push-notifications, internationalization, UI navigation, etc.), you get a “ready-to-go” foundation that you can build on immediately. For many simple or medium-complexity apps (MVPs, prototypes, early-stage mobile products), that can be a significant time-saver.

Created by Apparence, ApparenceKit offers a robust foundation for building scalable SaaS applications.
