What is Supastarter

Supastarter is a full-stack starter kit for building SaaS products with Next.js, Nuxt, or TanStack Start. It includes authentication, payments, organizations, API infrastructure, admin tools, email, storage, analytics, background jobs, SEO, and AI-ready workflows in a production-focused codebase.

Overview

Supastarter gives developers a complete starting point for a SaaS application instead of making them assemble the usual infrastructure themselves. The current product supports Next.js, Nuxt, and TanStack Start. The Next.js version uses a structured monorepo with separate marketing and SaaS applications. It includes authentication, multi-tenant organizations, billing, email, storage, analytics, monitoring, background jobs, admin functionality, SEO, testing, and AI workflows. Payment providers include Stripe, Lemon Squeezy, Polar, Creem, and Dodo Payments. The source code is provided after purchase and can be customized for unlimited commercial projects under the applicable license.

Who should and shouldn't use it

Should use it
  • You are building a serious SaaS product and want the core infrastructure ready

  • You are using Next.js, Nuxt, or TanStack Start
  • You want to choose between several payment providers
  • You want a codebase that works well with AI coding agents
  • You expect your product to need multi-tenancy, roles, APIs, email, storage, analytics, and background jobs
Shouldn't use it
  • You want a very small and minimal starter
  • You are building a simple landing page rather than a full SaaS product
  • You do not want to work with the supported frameworks
  • You want a free open-source boilerplate
  • You prefer a hosted SaaS builder instead of owning and modifying the application code
