Supastarter

Supastarter is a comprehensive Next.js, Nuxt, and SvelteKit SaaS starter kit designed to accelerate production-ready application development. Created and maintained by Jonathan Wilke and team, it provides integrated solutions for authentication, payments (supporting Stripe, Lemonsqueezy, and Chargebee), and internationalization out of the box.

Trusted by 600+ developers globally, Supastarter delivers an estimated 80+ hours of development time savings. The codebase receives regular updates (last update: 5 days ago) and comes with lifetime access under a one-time purchase model. Built on a fully serverless stack, it maintains enterprise-grade code quality with TypeScript support and comprehensive documentation.

Ideal for indie hackers and developers building scalable SaaS applications, Supastarter distinguishes itself through its full-stack integration, featuring ready-to-use components for auth flows, billing management, and AI capabilities via Vercel's AI SDK. It's particularly valuable for teams prioritizing speed-to-market without compromising on quality.

Technical benefits include Hono.js and Prisma backend architecture, type-safe API clients, and flexible database support. The framework accelerates development through CLI tooling, pre-built email templates, and shadcn/ui compatibility, while offering complete customization freedom through Tailwind CSS and Radix UI components.
