The Problem with Starting a SaaS from Scratch
I've been building on the internet for a while now — products, templates, tools. And the single most frustrating part of launching anything new is always the same thing: setup.
You want to build your idea. But first you need:
- Authentication (email + OAuth)
- A payment system with webhooks
- An email marketing pipeline
- A blog or CMS
- An admin dashboard
- Role-based access control
- A database schema
- And on and on...
By the time you've wired all of this together, you've spent 4–6 weeks and haven't built a single feature that's unique to your product.
That's exactly why I built BuildSAAS.
What is BuildSAAS?
BuildSAAS is a production-ready Next.js 15 SaaS starter boilerplate — everything you need to launch a subscription-based product, pre-wired and ready to go.
Not a tutorial. Not a YouTube series. Actual working code you clone, configure, and ship.
🚀 Demo: buildsaas-s18e.vercel.app
🛠 Admin: buildsaas-s18e.vercel.app/admin
📚 Docs: buildsaas-s18e.vercel.app/docs
What's Inside
🔐 Authentication & User Management
Firebase Auth out of the box — email/password, Google OAuth, email verification, password reset, and full role-based permissions (Admin, Editor, Author, Viewer). Your users are handled from day one.
💳 Payments & Subscriptions
Polar integration gives you a full subscription lifecycle: checkout flow, webhook handling, cancellation, upgrade emails, revenue analytics, and customer records. Everything you need for a real billing system.
📧 Email Marketing
Resend integration with newsletter campaigns, batch sending (50 recipients per batch), transactional emails for subscription events, and delivery tracking. No third-party email SaaS subscription needed at the start — Resend's free tier covers you up to 3,000 emails/month.
📝 Blog / CMS
A full blog system with a Tiptap rich text editor, markdown support, image uploads, draft/published workflow, and SEO-friendly slugs. Content management you'd normally pay a separate service for.
🖥 Admin Dashboard
A proper admin panel with analytics, user and customer management, payment tracking, contact form inbox, global search (Cmd+K), and role-based access. The kind of thing that takes weeks to design and build — already done.
The Tech Stack
No legacy dependencies. No bloated setup.
- Frontend: Next.js 15.1.7, React 18, Tailwind CSS 3, Framer Motion, Lucide Icons
- Backend / DB: Firebase (Auth, Firestore, Storage) + optional Supabase (PostgreSQL)
- State: Redux Toolkit + TanStack Query (React Query)
- Payments: Polar
- Email: Resend
- Editor: Tiptap with image uploads, markdown, text formatting, code blocks
- Language: TypeScript throughout

Why I Built This
I've spent years building products — and every single time, the first few weeks are the same grind. I wanted to stop repeating myself and create the foundation I wish existed when I started.
BuiltSAAS is that foundation. It's not a toy project. It's the real thing — production code, proper architecture, the integrations that every SaaS eventually needs.
Price: $49 — one time.
