Supastarter
Modular Next.js and Nuxt SaaS starter kit with full-stack TypeScript, billing, auth, and multi-tenancy built in.
Overview
Supastarter is a paid SaaS starter kit for Next.js and Nuxt that provides authentication, subscription billing, organizations (multi-tenancy), and marketing pages within a modular full-stack TypeScript architecture. It supports multiple payment providers, internationalization, and includes end-to-end testing and CI setup out of the box. The structure is designed for teams building multi-tenant SaaS products who want production-ready defaults without designing core infrastructure from scratch.
What is Supastarter?
Full-stack TypeScript with Next.js (React) and Nuxt (Vue) support, modular payment architecture, Playwright testing, GitHub Actions CI, and Docker-based development environment.
Best Suited For

Key Features of Supastarter
- True multi-tenancy with organizations built in
- Dual framework support: Next.js and Nuxt
- Modular multi-provider billing integration
- Full TypeScript with production-ready tests
- Built-in CI/CD with GitHub Actions
- Internationalization support included
- Docker-based local development setup
Advantages
- True multi-tenancy with organizations built in, reducing the need to design tenant boundaries manually.
- Supports both Next.js and Nuxt stacks under a shared architectural approach, offering flexibility across React and Vue ecosystems.
- Production-oriented setup including full TypeScript, Playwright tests, GitHub Actions CI, and Docker-based local development.
- Modular payment support designed to accommodate multiple billing providers rather than locking into a single integration.
Limitations
- Higher complexity than minimal SaaS starters due to built-in multi-tenancy, testing, and CI infrastructure.
- Opinionated patterns around authentication and billing mean core systems are integrated deeply and may require careful refactoring if swapped.
- May introduce unnecessary overhead for simple MVPs or single-tenant validation projects.
