What is the best Next.js SaaS boilerplate?
It depends on who your customers are. ShipFast is the quickest start for a solo, single-user product. Makerkit suits teams committed to Supabase. supastarter fits teams that also want a Nuxt version. supastack fits B2B and AI products: its Next.js 16 app costs $149 one-time and includes team workspaces, eight payment providers, API keys, signed webhooks and 13 languages, with optional mobile, desktop and TanStack Start apps on the same backend.
The short answer
Next.js has the most SaaS boilerplates of any framework, so the hard part is not finding one but finding one that matches the product you will run a year from now. Four starters cover most needs.
- Pick supastack if you are building a B2B or AI product that needs team workspaces, API keys, webhooks and room to add mobile or desktop apps later.
- Pick supastarter if you want the same kit in Next.js and Nuxt.
- Pick Makerkit if your team is committed to Supabase Auth and row-level security.
- Pick ShipFast if you are validating a single-user idea alone and speed matters more than structure.
What a Next.js boilerplate should include
Next.js gives you routing, server components, server actions and a strong deployment story. It does not give you accounts, billing or tenant isolation. These are the parts to check before you buy any starter:
| What to check | Why it matters |
|---|---|
| Server actions that check the session and workspace role | A server action is a public endpoint; each one must confirm who is calling |
| Payment webhooks that ignore repeat deliveries | Providers retry events, and a second delivery must not grant access twice |
| Teams from the first commit | Adding organizations later means changing every table and permission check |
| Sign-in you own | A hosted auth service can price you per user as you grow; an open library keeps users in your database |
| A real test suite | Without tests, every change to billing or sign-in becomes a manual check |
| A way to take in upstream updates | Next.js moves fast, and the starter should explain how to pull its fixes into your code |

When another starter is the better fit
supastack has more structure than a one-page template. If you only need a landing page and a Stripe button to test an idea this weekend, ShipFast has less to learn. If your whole stack already runs on Supabase, Makerkit follows its conventions closely. If you need Vue, supastarter's Nuxt version is the stronger choice.

Common questions about Next.js boilerplates
- Is a boilerplate still worth it when I use an AI coding agent? — Yes. Agents write screens quickly but often get billing retries and tenant checks wrong. A tested starter gives them working patterns to copy.
- Can I host a supastack Next.js app outside Vercel? — Yes. It runs on Vercel, in Docker or on your own server; the docs include a Google Cloud Run guide.
- Do I have to buy the mobile and desktop apps? — No. The Next.js app is $149 on its own. Any two platforms cost $298, and all four (Next.js, TanStack Start, Expo and Tauri) cost $299. See [pricing](/pricing).
- How do I get updates without losing my changes? — supastack keeps shared code in packages and documents an update workflow for pulling in new releases.
