Next.js Boilerplates and Starter Templates: The 2026 Shortlist
The shortlist is short: ixartz's Next.js Boilerplate as a strict general-purpose base, create-t3-app for a typed full stack, Vercel's SaaS Starter or BoxyHQ for subscription products, next-forge for a production monorepo, and the official Supabase starter when Supabase is your backend.
The shortlist
Next.js has more boilerplates than any other framework, and almost all of them are one of these six wearing different CSS:
| Template | Best for | What is included | Licence |
|---|---|---|---|
| Next.js Boilerplate (ixartz) | General-purpose apps with strict engineering defaults | Strict TypeScript, Tailwind, ESLint, testing, i18n, agent-friendly conventions | MIT |
| create-t3-app | Typed full-stack without a separate backend | tRPC, Prisma or Drizzle, Auth.js, Tailwind — chosen interactively | MIT |
| Next.js SaaS Starter (Vercel) | Subscription products, lean start | Postgres, Stripe with portal, teams, shadcn/ui | MIT |
| SaaS Starter Kit (BoxyHQ) | B2B SaaS with enterprise requirements | SAML SSO, audit logs, teams, Stripe, Prisma | Apache-2.0 |
| next-forge | Production monorepo from day one | Turborepo, auth, billing, docs, analytics, email — batteries included | MIT |
| Supabase starter (official) | Supabase as backend | Cookie-based Supabase Auth across App Router, middleware wired | MIT |
Authentication: the feature that saves the most time
Every Next.js authentication boilerplate is really a bet on one of three providers. Auth.js (formerly NextAuth) is open source and self-hosted — most flexible, most wiring. Clerk is hosted with prebuilt components — fastest, per-user pricing. Supabase Auth comes free with the database and handles sessions via cookies across server and client components.
The honest advice: pick the boilerplate whose auth choice matches where your users' data must live, because swapping auth providers later touches every protected route. This decision outweighs any difference in CSS frameworks or folder layout.
Stripe wiring is where templates earn their keep
A real Stripe integration is webhooks with signature verification, idempotent event handling, plan changes, proration and the customer portal. Templates in the shortlist ship all of it; code generated from a prompt reliably ships the happy path and nothing else. Given that roughly 44% of AI code-generation tasks introduce a vulnerability, billing is the clearest case for inheriting community-audited code instead of generating your own.
Vercel templates and one-click deploy
Vercel's template gallery covers hundreds of starters — every entry is a GitHub repository behind a Deploy button that clones it into your account and provisions hosting, previews and CI in one flow. It is the fastest legitimate path from template to a URL.
The button does not eliminate configuration: environment variables — database URL, auth secrets, Stripe keys — remain yours to supply, and a template's setup cost is roughly proportional to how many it requires. Nothing about these templates locks you to Vercel either; they remain standard Next.js repositories deployable anywhere Node runs, or via Docker.
Production-ready is a checklist, not a claim
Most templates advertising themselves as production-ready mean 'it builds'. Before trusting the label, check for:
- Error tracking and structured logging wired to a real destination, not console.log.
- Rate limiting on every public mutation — auth endpoints first.
- Security headers and a Content-Security-Policy that is not commented out.
- CI that runs typecheck, lint and tests on every pull request.
- At least one end-to-end test proving signup → login → paid action works.
- A documented upgrade path — templates that vendor their own framework forks die at the next Next.js major.
Next.js with a Python backend
Teams whose ML or data logic lives in Python pair a Next.js frontend with FastAPI. Vercel maintains a nextjs-fastapi hybrid template where FastAPI runs as serverless functions behind the Next.js app; at larger scale the two are usually split into separate services behind one domain. The full-stack-fastapi-template covered in our SaaS boilerplates guide is the reference for the standalone variant.
Whichever assembly you pick, the discovery problem stays the same: the differentiated part of your product usually already exists as an open-source component. The RepoLoot catalog analyses 491 of them — difficulty, licence, commercial potential — so the boilerplate is where your work starts, not where your research does.
Frequently asked questions
- What is the best Next.js boilerplate in 2026?
- For a general app: ixartz's Next.js Boilerplate or create-t3-app. For SaaS: Vercel's Next.js SaaS Starter, or BoxyHQ's kit when you need SSO and audit logs. For a monorepo: next-forge. All are MIT or Apache-2.0 licensed and actively maintained.
- Is there a free Next.js SaaS boilerplate?
- Yes — Vercel's Next.js SaaS Starter (MIT) ships Postgres, Stripe with a customer portal and a teams model; BoxyHQ's SaaS Starter Kit (Apache-2.0) adds SAML SSO and audit logs. Paid kits mostly add polish and support on top of the same architecture.
- How do I deploy a Next.js template to Vercel?
- Use the template's Deploy button, or import the GitHub repository at vercel.com/new — Vercel builds on every push and gives preview deployments per pull request. You supply the environment variables (database, auth secrets, Stripe keys); the template's README lists them.
- Can I use Next.js with FastAPI?
- Yes. Vercel's nextjs-fastapi template runs FastAPI as serverless functions behind the Next.js frontend — good for small APIs and ML endpoints. Larger systems typically deploy FastAPI separately and point the frontend at it; both patterns are standard in 2026.
