BetterAuthKit: The Ultimate Next.js 15 Auth Starter You’ve Been Waiting For

Publish Date: Jun 16
0 1

Authentication is often one of the most time-consuming and error-prone parts of building modern web applications. Whether you're launching a SaaS platform, building a dashboard, or experimenting with a personal project, having a secure and scalable auth system is non-negotiable.

That’s why I built BetterAuthKit — a production-ready authentication boilerplate powered by Next.js 15, BetterAuth, and Neon PostgreSQL, designed to help developers ship faster without compromising security or best practices.

🚀 Why BetterAuthKit?

BetterAuthKit takes care of all the essentials you need in a modern authentication system:

  • ✅ Google OAuth & Email/Password login
  • 🔒 Domain-based email restrictions (@gmail.com by default)
  • 📧 Secure password reset via email
  • 💻 Built with the latest Next.js 15 (App Router)
  • 🛡️ Security-first design with JWT sessions & hashed credentials
  • 🌱 Seamless integration with Neon (PostgreSQL) and Prisma
  • ⚙️ Fully typed with TypeScript

🧰 Tech Stack Overview

Tech Role
Next.js 15 Fullstack React framework
