Building a SaaS app from scratch is a bit like trying to bake a cake without a recipe — you know the ingredients (auth, payments, routing, databases), but mixing them right takes forever.
That’s where SaaS starter kits come in.
They’re like having a preheated oven and half the cake already done. You just add your flavor — your features — and it’s ready to serve.
In this post, I’ve rounded up some of the best SaaS starter kits for 2025, whether you’re building your first project or your tenth.
1. SassyPack (MERN + Stripe)
If setting up a full stack feels like untangling Christmas lights, SassyPack is the kit that plugs in perfectly on the first try.
It’s built on MERN (MongoDB, Express, React, Node) and gives you a fully working SaaS base out of the box.
What you get:
- Auth system (JWT + role-based access)
- Stripe payments already wired up
- Dashboard, landing pages, and layouts done for you
- Ideal for indie devs and founders who want to move fast

2. ShipFast (Next.js + Supabase)
ShipFast feels like a lightweight sports bike — quick to set up, fun to ride, and easy to tweak.
It combines Next.js with Supabase for a clean SaaS base: user auth, billing, and email templates all ready to go.
3. Divjoy (React + Firebase)
Divjoy is like a design studio in your browser.
Pick your favorite stack, choose your layout, and click “generate.” It’s ideal for developers who love to build fast but keep control over design and structure.
4. SaaS Boilerplate (Next.js + Prisma)
If you like your code like your workspace — tidy and efficient — you’ll love this one.
It’s built on Next.js + Prisma with a strong TypeScript setup and a focus on long-term scalability.
5. MakerKit (Next.js + Clerk + Stripe)
MakerKit feels like the Tesla of starter kits — sleek, reliable, and powerful.
It includes authentication (Clerk), payments (Stripe), and a polished UI built for performance.
Final Thoughts
Choosing a starter kit is a bit like picking your travel gear.
If you’re a solo founder sprinting to launch, SassyPack or ShipFast will feel fast and flexible.
If you’re building something long-term with a team, MakerKit or SaaS Boilerplate gives you the power and polish for the road ahead.
Whatever you pick, remember this:
The fastest way to learn is to launch. Don’t wait to build the perfect setup — just start, iterate, and grow.
