Fundamentals of SaaS Starter Kits

Everything You Get with SassyPack, The Next.js SaaS Starter Kit

5 min read

If you’ve ever tried to build a SaaS from scratch, you know the pain.
Auth, payments, routes, analytics, all before you even touch your actual product.

That’s why I built SassyPack, the complete Nextjs SaaS Starter Kit that handles all the boring parts for you, so you can focus on what matters, your product.

Let’s break down exactly what’s inside.


1. Modern Landing Page

Your first impression matters.
SassyPack comes with a responsive, modern landing page built with TailwindCSS + DaisyUI.

  • Pre-built sections for features, pricing, and CTAs
  • Mobile-friendly and SEO-ready
  • Fast-loading and optimized for conversions

All you have to do is update the copy and hit deploy.


2. Authentication System

Signup, login, logout, sessions, all ready to go.
You don’t need to wire up tokens or spend hours debugging your JWT setup.

  • Secure authentication flow (email + password)
  • Protected routes for user-only areas
  • Session persistence with refresh tokens
  • Clean, reusable code you can extend

3. Payments (Stripe + Paystack)

Monetize your SaaS instantly.
SassyPack includes built-in integrations for Stripe and Paystack, so you can start collecting payments in minutes.

  • One-time and subscription models supported
  • Works globally (Stripe) and regionally (Paystack)
  • Simple .env configuration for your API keys
  • Ready-to-use checkout flow for both platforms

Bonus: Analytics & Blog

Track everything with PostHog Analytics, and publish product updates through a built-in SEO-ready blog.

Because your SaaS should speak both code and content.
