Achromatic vs Nextless.js

When choosing between Achromatic and Nextless.js, 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 Nextless.js?

Nextless.js is a full‑stack SaaS boilerplate built with Next.js + React + TypeScript + Tailwind CSS on the front end and a serverless backend (via AWS and Serverless Framework) crafted to help developers launch subscription‑based or team/multi‑tenant apps quickly and with scalable infrastructure. It’s not just a UI skeleton: Nextless.js integrates authentication (with support for email/social login + optional MFA via AWS Cognito), subscription payments (via Stripe), multi‑tenant and team support (with tenant isolation and team/workspace membership), and both a user dashboard and an admin dashboard ready out of the box. Beyond core SaaS features, the boilerplate includes a landing‑page template, styling and theming capabilities (multi‑theme, responsive/mobile‑friendly design), and infrastructure-as-code support using AWS allowing for REST API via AWS Lambda, database options (PostgreSQL, MySQL, MongoDB, or DynamoDB), and serverless deployment.
