SAAS Starter Kit is an open-source boilerplate for building Software-as-a-Service applications on Next.js, bundling authentication, Stripe billing, an admin dashboard, and OpenAI integration so you can start on your core product immediately.
What is SAAS Starter Kit?
SAAS Starter Kit is a production-ready SAAS boilerplate built with React.js, Next.js, TypeScript, Tailwind CSS, Shadcn, Stripe, NextAuth, Prisma, Postgres, and Playwright. It provides the standard features every SAAS product needs — admin dashboard, authentication with Google social login, user profile management, Stripe subscription payments, checkout pages, landing and pricing page templates, CRUD operations, and OpenAI integration — so developers skip weeks of setup and focus on their unique application. The open-source repository lives on GitHub with 625 stars, and a paid Pro version adds multi-tenancy, roles and permissions, team invites, and more.
Key Features
- Admin Dashboard — A ready-to-use admin area included in the free template, giving you a starting point for managing users and application data.
- Full Authentication with Google Social Login — NextAuth-powered sign-in flows, including Google OAuth, plus email-based authentication out of the box.
- User Profile Management — Users can change their email and username through built-in profile pages.
- OpenAI Integration — The template comes with OpenAI API integration wired in, useful for building AI features like chat or content generation directly into your SAAS.
- Stripe Subscription Payments — Stripe checkout pages and subscription billing are implemented, so recurring revenue is handled from day one.
- Checkout Pages — Pre-built checkout flow for Stripe payments, ready to connect to your pricing page.
- Landing and Pricing Page Template — A marketing page and pricing page template are included to give your product a starting presence.
- Testing Setup with Playwright — End-to-end testing configuration with Playwright is included in the boilerplate.

Who is it for?
SAAS Starter Kit is for developers who want to launch a subscription-based web application without rebuilding the same plumbing. It suits indie hackers who need a fast starting point for a paid product, startups that require ready-made Stripe billing and auth, and AI-focused teams that want to integrate OpenAI-powered features into a Next.js app. It's also useful for freelancers who build multiple SAAS products and need a consistent foundation.
What can you do with it?
- Indie founders: Launch a SAAS product with landing page, pricing page, authentication, and Stripe subscriptions already connected.
- AI product builders: Use the built-in OpenAI integration to add chat or content-generation features to your app quickly.
- Full-stack developers: Extend the boilerplate's CRUD operations and Prisma schema to model your own domain.
- Agencies: Ship client projects faster with a prebuilt admin dashboard, auth, and payment setup that can be customized per project.
