Best Next.js Boilerplates in 2026
Paul TherbieoWhat Is a Next.js Boilerplate?
A Next.js boilerplate is a pre-built starter template that gives you everything you need to launch a SaaS product: authentication, payments, database, email, and UI components, all wired together and ready to go.
Instead of spending 4 to 6 weeks setting up infrastructure, you clone a boilerplate and start building your actual product on day one. For indie developers and early-stage startups, that speed advantage is the difference between shipping and stalling.
What to Look For in a Next.js Starter Kit
The best Next.js SaaS boilerplates in 2026 include all of these:
- Authentication: Clerk, NextAuth, or Supabase Auth
- Payments: Stripe Checkout and subscription management
- Database: Prisma, Drizzle, or a managed option like Supabase
- Email: Resend or Postmark for transactional email
- UI: shadcn/ui or Tailwind CSS component library
- TypeScript: Full type safety across the stack
- SEO: Metadata, sitemaps, and Open Graph support out of the box
If a boilerplate is missing payments or auth, expect to spend days integrating them yourself.
Top Next.js Boilerplates in 2026
1. Supastarter
Supastarter is one of the most complete Next.js SaaS starter kits available. Built around the Supabase ecosystem, it gives you a fully managed Postgres database, real-time subscriptions, and row-level security out of the box.

Key features:
- Custom stack selection at generation time

Frequently Asked Questions
Is a Next.js boilerplate worth it in 2026?
Yes. The recurring cost of setting up auth, payments, and email from scratch is 3 to 6 weeks of engineering time. A boilerplate eliminates that entirely and gives you a codebase that has already been tested in production by other developers.
Which Next.js boilerplate is best for solo founders?
Supastarter works well for solo founders because the Supabase backend requires minimal DevOps. You get a production-ready database, auth, and storage with zero server management.
Can I use these boilerplates with Vercel?
Yes. Both boilerplates above are optimized for Vercel deployment and support edge functions and serverless APIs.
