Achromatic vs NextJet

When choosing between Achromatic and NextJet, 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.

What is NextJet?

NextJet is a full‑stack SaaS boilerplate built with Next.js, TypeScript and modern web‑app tooling, made to give developers a solid, production‑ready foundation when building subscription‑based or SaaS‑style applications. Out of the box it handles core infrastructure: user authentication + authorization (including OAuth and magic‑link support), payment/subscription logic via Stripe or Lemon Squeezy, and pre‑built user dashboards + admin panel. It also includes content‑management and marketing‑side features: a blog and documentation system using MDX, a customizable landing/marketing site, email templates, and onboarding flows. The project follows a modular, maintainable architecture (monorepo via Turborepo, clean folder structure, typesafety via TypeScript), which helps keep code organized, useful if you plan to grow or scale the app over time. Because much of the “plumbing” is already configured, you can skip repetitive setup and get to building your product‑specific logic faster. At the same time, using NextJet means trusting its built‑in architecture, tech stack and conventions. If your project needs a very different stack, unusual backend/data requirements or a minimal footprint, you might need to refactor or drop parts of what comes with the boilerplate.
