A Next.js boilerplate is a starter codebase with sign-in, payments and a marketing site already built. Three paid kits worth comparing in 2026 are ShipFast, Supastarter and shipanysaas; two popular free ones are the Next.js SaaS Starter and ixartz's SaaS Boilerplate. They differ most on price, teams, database and whether a phone app comes too.
A note before the tables: this blog belongs to shipanysaas, one of the six. Every fact about the other kits comes from its own website or GitHub repository, linked below, and was checked on 18 October 2026. Prices and plans change often, so check the kit's own page before you buy. Where another kit is stronger, this post says so.

"Not listed" means the kit's own site or README doesn't mention it, not that it can't be built.
ShipFast: who is it for?
ShipFast suits a solo founder who wants one simple Next.js app and a big community of other makers. It is a single project, not a monorepo, and you choose JavaScript or TypeScript, the App Router or the Pages Router, and MongoDB or Supabase.
Where it is stronger:
- Community. All-in and the bundle include a Discord that the FAQ puts at 5,000+ makers, plus Leaderboards that rank customers' startups by revenue verified through Stripe. The home page counts 8,437 makers.
- Simplicity. One app with fewer moving parts is easier to read, for you and for your coding agent.
- Founder extras. All-in lists $1,210 of partner discounts, mostly on marketing tools, and the bundle adds the CodeFast course.
Watch for: lifetime updates, the Discord and the discounts come with All-in and the bundle, not Starter. Teams, roles, an admin panel and a phone app aren't listed, so a product that sells to companies starts by building them. The full side-by-side is in shipanysaas vs ShipFast.
Supastarter: who is it for?
Supastarter suits a team that wants to choose its own framework, ORM and payment provider, or sells in several languages. One purchase covers one framework: Next.js, Nuxt or TanStack Start.
Where it is stronger:
- Choice. Prisma or Drizzle, PostgreSQL by default, five payment providers, and better-auth for sign-in, with passkeys and two-factor built in.
- Languages. Translations, a language switcher and translatable emails ship ready.
- Plans for development teams. Startup covers up to five developers and Agency up to ten, both with priority email support and a 60-minute consulting call.
- Track record. The FAQ says the kit has been maintained for over two years and puts its Discord at 1,200+ members. The changelog's latest entry is dated 9 October 2026.
Watch for: despite the name, Supabase is optional, and the mobile app starter is still on the roadmap. Its FAQ, licence and terms don't state a refund policy, so ask before you pay. More detail is in shipanysaas vs Supastarter.
shipanysaas: who is it for?
shipanysaas suits a solo founder or small team that builds with a coding agent and needs a web app, and possibly a phone app, on one Supabase backend. It is a Next.js 16 web app; the All-in plan adds an Expo app for iPhone, iPad and Android with the same sign-in, teams and plan.
What it brings:
- A phone app on the same backend. With All-in, both apps share Supabase sign-in, personal and team accounts, roles and invitations. Customers pay on the website, and the phone app shows the plan.
- Teams and an admin panel. Team accounts, roles, email invitations, and a super-admin panel that requires two-step sign-in.
- Data isolation you can test. Row-level security is on for all 13 public tables. Of the 23 pgTAP database test files, 13 sign in as one account and try to read or change another's data. See row-level security.
- Set up for coding agents. AGENTS.md routes every agent, with setup for ten named agents. Starter ships 42 agent skills and 6 written fixes for setup errors; All-in ships 49 skills and 17 fixes. See coding agents.
- Client projects on one licence. Unlimited products, yours or your clients'.
Where others are stronger: shipanysaas is new, with no Discord, community or track record yet. It is Supabase only, with two payment providers. It is set up for translation, but only English ships. It has no AI features in the product, and no background job queue.
Free Next.js boilerplates
Both free options are MIT-licensed, so you can read, change and ship them at no cost. Either is a good way to learn how the pieces fit before you pay for anything.
Next.js SaaS Starter lives in the Next.js team's GitHub organisation, with about 16,200 stars. It uses Postgres with Drizzle, email-and-password sign-in with JWTs stored in cookies, Stripe Checkout and the Customer Portal, and teams with Owner and Member roles. Its README calls it "intentionally minimal and to be used as a learning resource". Its last commit, on 11 December 2025, moved it to a Next.js 15.6 canary release.
ixartz SaaS Boilerplate has about 7,500 stars and was last pushed on 1 October 2026. It runs Next.js 16 with Drizzle and Clerk for sign-in, and its free version includes organizations, role-based permissions, translations with next-intl, and Vitest and Playwright tests. Stripe is in the paid Plus, Pro and Max versions only, and sign-in depends on Clerk, a hosted service.
Which Next.js SaaS boilerplate should you pick?
Start from what your product needs in its first year, then pick the smallest kit that covers it:
- Learning, or a tight budget: the Next.js SaaS Starter. Small enough to read in an afternoon.
- Free, with organizations and translations: ixartz's SaaS Boilerplate, if Clerk for sign-in suits you.
- One web app, a big community and MongoDB as an option: ShipFast.
- Your choice of framework, ORM or payment provider, several languages, or a development team: Supastarter.
- Web and phone on one Supabase backend, teams, tested data isolation and a repository set up for your coding agent: shipanysaas.
Whichever you pick, check a few things before you pay: sign in to a live demo, find the database tests and run them, read the webhook handler, and follow one feature through the docs. Build it or buy it has the full checklist, and Polar vs Stripe vs Lemon Squeezy helps with the payment provider.
shipanysaas has a live demo of the web app, with a shared login you open in one click and a reset every hour, and a web build of the phone app. Both are linked from the pricing page.
FAQ
Is there a free next js boilerplate with Stripe?
Yes. The Next.js SaaS Starter is MIT-licensed and includes Stripe Checkout, the Customer Portal and teams with two roles. ixartz's free SaaS Boilerplate doesn't include Stripe; that is in its paid versions.
Which Next.js starter kit has a mobile app?
Of the five, shipanysaas (All-in plan) offers an Expo app on the same Supabase backend as the web app. Supastarter lists a mobile starter as planned. ShipFast and the two free kits don't list one.
Can I get a refund on a Next.js boilerplate?
Usually not. ShipFast and shipanysaas don't refund once you have the code. Supastarter's site doesn't state a policy. Try the demos and read the docs first.
Can I use a boilerplate for client projects?
It depends on the licence. shipanysaas and Supastarter allow client projects; Supastarter's Agency plan is the one that lists them. ShipFast's licence covers unlimited projects, as an individual or a team.
Should I build my own Next.js SaaS boilerplate instead?
Build your own if you want to learn, your needs are unusual, or you would rewrite most of a kit anyway. Otherwise, sign-in, teams, billing webhooks and data rules take weeks that a kit has already spent. Build it or buy it goes through the trade.
