Supastarter
PaidSaaS starter kit for Next.js and Nuxt with authentication, organizations, subscription billing, internationalization, an AI-ready setup, and a clean typed data layer. Ship a production SaaS in days. Paid, from $299 one-time.
Why we recommend Supastarter
Supastarter's differentiator in the crowded Next.js SaaS-kit market is that it isn't only a Next.js kit: it ships parallel starters for Next.js and Nuxt on a shared architecture, which makes it the default choice for Vue-side founders who are otherwise ignored by this market. The kit covers the full B2B checklist — auth with organizations/teams, subscription billing, i18n, emails, and a documented data layer — and its docs explain how the pieces connect rather than assuming you'll never look inside. Updates have been steady for years, and the maintainer is responsive on Discord.
Best use cases
Best for: Nuxt/Vue developers who want a ShipFast-class head start without switching frameworks, TypeScript teams that want organizations + billing + i18n solved on day one, and European founders (i18n and localized pricing are first-class, not bolted on).
Honest limitations
Not for: developers expecting one canonical stack — supporting multiple frameworks means some integrations land on one flavor before the other. Paid (from $299 one-time), closed-source, single maintainer. As with all kits, heavy customization of the built-in billing flows means maintaining your own fork.
