Best Next.js SaaS Boilerplates 2025: 10 Options Ranked and Reviewed

We reviewed each boilerplate by reading the code, not just the documentation. Marketing pages claim feature parity that the underlying code does not always support. We specifically looked at four common failure modes. First, auth implementation quality. Many boilerplates use outdated auth patterns. We looked for NextAuth.js v5 or Clerk integration, proper session management, and route protection that works with Next.js App Router, not just the legacy Pages Router. Auth that works on Pages Router only is a serious limitation for new projects starting in 2025. Second, Stripe integration completeness. Billing is the most complex part of most SaaS products. We wanted to see subscription management, webhook handling, customer portal integration, and usage-based billing support, not just a basic checkout flow. Third, TypeScript coverage. A boilerplate with 40% TypeScript coverage saves less time than one at 95%. Type safety across the full stack, including database schemas via Prisma or Drizzle with TypeScript, is what makes the boilerplate genuinely maintainable. Fourth, AI readiness. In 2025, most SaaS products ship with AI features. We assessed whether each boilerplate includes AI SDK integration (Vercel AI SDK is the most common), streaming response handling, and API route patterns suitable for LLM calls. This was a differentiating factor: several established boilerplates have not caught up to AI development patterns yet. Active maintenance matters because Next.js itself moves fast. A boilerplate last updated 18 months ago is likely using deprecated App Router patterns and outdated dependencies.

1. Shipfast (Marc Lou). The best-maintained commercial SaaS boilerplate in 2025. Stripe billing, email, auth, and SEO components included. AI features added. Regular updates. Priced as a one-time purchase. Best for indie founders and small teams wanting a proven, complete starter. Limitation: commercial licence adds cost (approximately USD 199). 2. Next.js SaaS Starter (Vercel). The official Vercel-maintained starter. Uses NextAuth, Stripe, and Postgres. Very clean TypeScript. Vercel-deployment-optimised. Best for teams deploying on Vercel. Limitation: less opinionated on UI, which means more setup time for visual components. 3. Superstarter. Full-featured boilerplate with i18n, auth, billing, and team management out of the box. Good for multi-tenant SaaS products. Limitation: higher complexity means a steeper onboarding curve. 4. Makerkit. Battle-tested Next.js and Supabase boilerplate. Strong auth patterns. Good community. AI examples being added. Best for teams choosing Supabase as their database and auth layer. Limitation: Supabase-opinionated, less suited to teams wanting Postgres directly. 5. T3 Stack (create-t3-app). The community standard for type-safe Next.js apps with tRPC, Prisma, and Tailwind. Extremely well-maintained. Best foundation for teams who want maximum TypeScript discipline. Limitation: not a SaaS boilerplate per se, you build on the T3 scaffold rather than modify a complete product. 6. Taxonomy (shadcn). The shadcn/ui author's reference SaaS implementation. Excellent UI quality. Clean App Router implementation. Best for teams planning to use shadcn/ui components throughout. Limitation: less complete on billing than commercial alternatives. 7. SaaS Starter (Lemon Squeezy). Uses Lemon Squeezy as the payment processor rather than Stripe. Good for founders who find Lemon Squeezy's merchant-of-record model appealing. Limitation: less community support than Stripe-based alternatives. 8. Bedrock (enterprise). Opinionated enterprise SaaS starter with Nx monorepo, strong auth, and compliance features. Best for teams building multi-product SaaS platforms. Limitation: significant over-engineering for a simple MVP. 9. Divjoy. Code generator rather than a static boilerplate. Generates customised Next.js projects based on your feature selections. Best for teams who want a tailored start without committing to one template. Limitation: generated code quality varies. 10. Open-source alternatives (Blitz.js, Redwood.js). Full-stack JavaScript frameworks with SaaS conventions. Strong community. Best for teams who prefer opinionated frameworks over boilerplates. Limitation: not Next.js native, which limits ecosystem compatibility.

The most important choice is between paid commercial boilerplates and free community ones. Paid boilerplates (Shipfast, Superstarter, Makerkit) are actively maintained because the developer has a financial incentive to do so. Free community boilerplates are maintained by goodwill and may stagnate. In fast-moving areas like Next.js App Router compatibility and AI SDK integration, recency of maintenance is a genuine quality signal. On AI readiness specifically, only Shipfast and the Vercel starter have consistent AI feature examples. This matters if your product has AI features from day one, which in 2025 means the majority of new SaaS products. A boilerplate that does not have streaming response patterns or Vercel AI SDK integration will cost your team 2 to 5 days of setup that a well-chosen boilerplate includes. On the auth question, Clerk versus NextAuth is the main debate. Clerk provides a polished hosted auth experience with excellent UI components and organisation/team management built in. It costs money at meaningful user volumes (typically USD 25 per month plus per-user fees above the free tier). NextAuth is free and flexible but requires more implementation work. For MVPs targeting rapid growth, Clerk's time savings often justify the cost. For founders who want to minimise SaaS dependencies, NextAuth is the right choice. GDPR and data residency: boilerplates are foundations, not products. Their GDPR compliance depends on how you configure your infrastructure. That said, boilerplates using Supabase (EU region), Vercel (with EU data residency options), and Resend for email (with appropriate DPAs) can be configured GDPR-compliantly. Make this part of your infrastructure setup, not an afterthought.

Your boilerplate choice should follow your tech stack decisions, not precede them. Before choosing a boilerplate, decide: which database (Postgres directly via Prisma/Drizzle, or Supabase, or another managed service), which auth (Clerk, NextAuth, Auth.js), which payment processor (Stripe, Lemon Squeezy, Paddle), and which deployment platform (Vercel, Railway, AWS). Once those are decided, find the boilerplate that matches. If you are using Supabase, Makerkit is purpose-built. If you are deploying on Vercel and want official support, the Vercel SaaS Starter is the obvious choice. If you want maximum features in a single commercial purchase and plan to ship quickly, Shipfast covers the most ground. For teams building AI products specifically, assess the boilerplate's AI patterns before choosing. Download the repo and check whether it has Vercel AI SDK installed, whether it has example streaming API routes, and whether it has patterns for handling LLM provider API keys securely. Missing these means your first sprint is spent adding infrastructure rather than building product. For teams working with SpeedMVPs, this decision is typically made during the scoping call. SpeedMVPs has established boilerplate configurations it works from, which is part of how the 2 to 3 week delivery timeline is achievable. Starting from a mature, tested foundation eliminates the setup sprint that slows down teams using novel configurations.

For most founders starting a new SaaS product in 2025, Shipfast is the most complete single purchase that handles auth, billing, email, and AI patterns together. The one-time USD 199 cost is recovered in the first day of development time it saves. For teams who prefer not to start from commercial boilerplates, the T3 stack with Makerkit or Taxonomy patterns layered on top gives excellent TypeScript discipline and community support. For AI-native products being built by an agency, the boilerplate choice is less significant because a specialist agency brings its own battle-tested foundation. SpeedMVPs uses established Next.js foundations with AI SDK integration, Stripe billing, and Clerk auth as default choices, adapted to each project's specific requirements.
