NextStarter — Production-Ready SaaS Starter (Next.js 16 · Supabase · Stripe)

NextStarter is a production-shaped SaaS starter built with Next.js 16 (App Router), React 19, TypeScript, Supabase Postgres + Prisma, Auth.js v5, and Stripe. It ships authentication (Google + email/password), teams & organizations, Stripe billing, an admin panel, moderation, contact/support, transactional email, notifications, a hand-built Tailwind v4 design system, and a Playwright E2E suite — every piece wired together and verified, so you can launch your product instead of building plumbing.
