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.

CodePilot is a paid SaaS‑boilerplate based on Next.js + Prisma + TypeScript. It aims to give you a full, ready‑to‑code foundation so you don’t have to build from zero: auth, payments, dashboards, email, blog/landing pages and more are already wired up. Out of the box you get a functional user dashboard and admin panel, auth support (with credentials, magic‑link or OAuth/social providers), Stripe‑based payments, email templates (via Resend), a landing page + blog + SEO content structure, and a prebuilt UI component library (with styling, animations and customization options) so you can ship quickly.

DaaSBoilerplate is a ready‑made starter kit aimed at people who want to launch a “Data as a Service” product quickly a web application where you provide data or datasets to customers, with access control, payment, and management all built in. When you get DaaSBoilerplate, you receive a production‑ready codebase built on Next.js + TypeScript, configured to run with Docker for easy deployment. It comes with built-in user authentication and multi‑tenancy (so you can support multiple accounts or organizations), an admin panel and user dashboard, payment integrations (via Stripe and Lemon Squeezy), and tools for content & marketing: blog, documentation or marketing pages, which makes it easier to launch publicly without building CMS or marketing infrastructure from scratch. On top of that, DaaSBoilerplate claims “one‑click deployment” via Docker, plus data‑upload / import functionality meaning you can upload or change dataset content and have it available quickly, which is core if you plan to provide data to customers rather than a traditional SaaS feature set.
