Achromatic vs ReactApp

When choosing between Achromatic and ReactApp, 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 ReactApp?

ReactApp is a full‑stack SaaS starter built with React + Next.js + Firebase that aims to help developers launch web applications quickly without wiring everything manually. Its stack combines frontend (React & Next.js), UI styling (Tailwind CSS), backend and hosting (Firebase: authentication, Firestore database, serverless functions, hosting), plus built‑in infrastructure for payments (Stripe), transactional emails (Postmark), and optional utilities like a cookie banner, analytics support, and a chat widget for user interaction. With ReactApp you get a project structure where authentication flows (sign‑up/login/reset), user sessions, secure database, payment/subscription handling, and UI/layout scaffolding are already configured. This lets you skip much of the usual boilerplate: routing, backend setup, admin/user flows and go straight to building custom features.
