DaaSBoilerplate

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.

BuilderKit.ai is a boilerplate / starter‑kit built with Next.js + Supabase + Tailwind CSS + TypeScript, aimed at helping developers launch AI‑powered SaaS/web applications quickly. Rather than being a minimal template, BuilderKit comes pre‑wired with modules and features that cover many needs for an AI SaaS: authentication (email, Google auth, magic‑link), payments (via Stripe or LemonSqueezy), email integrations, admin dashboard, SEO‑friendly landing pages & waitlist pages, and even pre-built AI‑app demos. On top of that, BuilderKit bundles 10‑15+ ready-to-use AI tools / applications: for example chat, image generation, PDF‑chat, voice transcription, image‑enhancing / upscaling, and more, so you don’t just get a skeleton, but a suite of working AI‑powered features you can build on or customize. he code is distributed via a GitHub repo, and once set up (with environment variables, dependencies installed, etc.) you can run and deploy the app commonly on platforms like Vercel.

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.
