Best Boilerplates with Subscriptions

31SaaS feels like a project built by someone who actually ships products, not someone assembling a checklist of features. The whole thing runs on Next.js 14, and the structure is clean in a way that makes sense the moment you open the repo — the kind of layout you’d probably set up yourself after a few iterations, just without the wasted weekend. The authentication flow, Stripe setup, and email handling are already connected and working, not half-finished stubs. The UI is put together with shadcn and Tailwind, so it looks modern without being overdesigned, and it’s easy to extend without fighting the styling choices. What stands out is that you can start building real features almost immediately. There’s a proper dashboard, a place for marketing pages, a blog engine that doesn’t feel like an afterthought, and small touches like sensible error handling and clean form patterns. It’s not trying to reinvent the wheel — it’s just a solid, well-assembled foundation that saves you from the usual setup grind. If you want a boilerplate that stays out of your way and lets you move quickly without later regretting the shortcuts, 31SaaS is one of the more thoughtfully built options out there.

Achromatic is a Next.js 15–based SaaS starter that tries to cover most of the groundwork developers usually build themselves: authentication, organizations, role management, billing, email, and a consistent UI built on shadcn/ui and Tailwind. The appeal is that it doesn’t just drop in loose components — the pieces are wired together in a way that feels closer to a real application than a template. The onboarding flow, subscription logic, and organization system actually work out of the box, which makes it easy to jump into feature development without spending days on the usual boilerplate chores. There are a few things worth noting, though. The project is relatively new, and the ecosystem around it is still small, so you’re buying into a structure that depends heavily on the maintainer’s ongoing involvement. It’s an opinionated setup, which is great if you like the architecture as-is, but less ideal if you prefer a lighter, more minimal foundation. Achromatic positions itself as a time-saver for developers who want a polished starting point rather than assembling every piece manually, and it mostly succeeds at that. Still, it’s best suited for teams comfortable adopting someone else’s patterns and conventions anyone needing maximum flexibility might find it a bit heavier than they’d like.

Bedrock is a full‑stack boilerplate for building SaaS products, built on Next.js and GraphQL. It’s designed to take care of the usual foundational work: user authentication, subscription payments (via Stripe), team/project support (multi‑project or multi‑tenant logic, invitations & membership handling), email integration, database setup, API wiring (using e.g. Prisma + GraphQL schema), and general plumbing like linting, formatting, code generation, and CI/testing setup. Importantly, Bedrock ships “unstyled” meaning it doesn’t impose a UI or design system on you. What it gives you is the backend logic, data flow, and structural foundation; the visual layer is entirely yours (or up to whatever UI framework/components you choose). Because of its modular architecture, many of the bundled tools and integrations are optional you can drop or swap parts if they don’t fit your preferences.

BuilderKit.ai is a boilerplate / starter‑kit built with Next.js + Supabase + Tailwind CSS + TypeScript, aimed at helping developers launch AI‑powered SaaS/web applications quickly. Rather than being a minimal template, BuilderKit comes pre‑wired with modules and features that cover many needs for an AI SaaS: authentication (email, Google auth, magic‑link), payments (via Stripe or LemonSqueezy), email integrations, admin dashboard, SEO‑friendly landing pages & waitlist pages, and even pre-built AI‑app demos. On top of that, BuilderKit bundles 10‑15+ ready-to-use AI tools / applications: for example chat, image generation, PDF‑chat, voice transcription, image‑enhancing / upscaling, and more, so you don’t just get a skeleton, but a suite of working AI‑powered features you can build on or customize. he code is distributed via a GitHub repo, and once set up (with environment variables, dependencies installed, etc.) you can run and deploy the app commonly on platforms like Vercel.

Cascade is a free, open-source SaaS starter kit based on the T3 stack (with Next.js + Prisma + PostgreSQL + TypeScript) that aims to give you a “ready-to-code business logic” foundation rather than a full-blown UI framework. Its core philosophy is minimal bloat. Once you clone the repo, provide environment variables and database config, you can have a working backend (auth, DB, basic flows) running locally in minutes. Cascade supports essential SaaS‑app plumbing such as authentication (via Auth.js / NextAuth + Prisma), database setup (PostgreSQL + Prisma), payments & billing (through Lemon Squeezy integration), background jobs (with Trigger.dev), error tracking (via Sentry), analytics (via self‑hostable or free‑plan friendly services like PostHog / Plausible), plus optional “business‑adjacent” pieces: a markdown-based blog via Contentlayer, email flows, server‑side rendering, and basic CI/CD / deployment setups.

CodePilot is a paid SaaS‑boilerplate based on Next.js + Prisma + TypeScript. It aims to give you a full, ready‑to‑code foundation so you don’t have to build from zero: auth, payments, dashboards, email, blog/landing pages and more are already wired up. Out of the box you get a functional user dashboard and admin panel, auth support (with credentials, magic‑link or OAuth/social providers), Stripe‑based payments, email templates (via Resend), a landing page + blog + SEO content structure, and a prebuilt UI component library (with styling, animations and customization options) so you can ship quickly.

Dirstarter is a full-featured boilerplate built with Next.js (with TypeScript) designed for launching directory-style websites. It gives you a ready-made foundation: authentication and user management, admin panel, listing submission and management, payment integration via Stripe, and monetization options (premium listings, featured spots, ads, affiliate-links, etc.). Beyond that, Dirstarter includes SEO-friendly page structure, support for multiple languages (i18n), and built-in tools for content creation (including AI-powered content generation to help bootstrap listings and categories). On the technical side, Dirstarter leans on a modern, maintainable stack: Next.js, a modern ORM (e.g. Prisma), CSS via Tailwind CSS, and UI components from shadcn/ui / Radix UI which means you’ll get a responsive, customizable UI and a code structure that’s relatively straightforward to work with and extend. The value proposition of Dirstarter is that instead of spending weeks building the backbone of a directory site: user flows, payments, listings DB, admin UI, monetization logic, i18n, SEO - you get a working system out-of-the-box and can focus immediately on content, branding, and growth. For someone building a directory or listing-type website (local businesses, tools marketplace, niche listing directory, etc.), this can significantly reduce time to launch. However, adopting Dirstarter also means accepting its architecture and conventions. It’s opinionated: you're committing to the tech choices (Next.js + Prisma + Tailwind + the integrations Dirstarter bundles). If your project requires a drastically different backend setup, custom data models or unusual flows, you may spend extra effort altering or stripping parts you don’t need. Moreover, because it offers a lot of built-in features (payments, content generation, monetization, i18n, admin, etc.), you may end up with more “surface area” than needed which can complicate maintenance if you only need a simple directory.

Dome SaaS Validation Template is a full‑stack boilerplate built on Next.js + Tailwind CSS, designed to help developers launch a SaaS MVP (minimum‑viable‑product) quickly. It bundles essential infrastructure authentication (social login, magic link, NextAuth), payment integrations (via Stripe and LemonSqueezy), email support (e.g. using Mailgun), analytics, and customer‑feedback tools (like chatbot or messaging integrations) all preconfigured to spare you the boilerplate wiring. On the frontend, the template provides a ready-to-use landing page, blog, pricing and FAQ pages, standard marketing and SaaS‑site sections (hero, features, testimonials, CTA, banners, etc.), and responsive layout out of the box. That means you don’t start with an empty shell, instead you get a functioning, production‑ready codebase where much of the common SaaS plumbing (UI pages, auth, payments, database logic via Prisma, etc.) is already connected. The main advantage of using Dome’s SaaS Validation Template is speed it reduces the time to launch a SaaS or MVP drastically by handing you a full stack ready for deployment, with integrations and default pages. This lets you focus on business logic, custom features, and go‑to‑market strategy instead of building foundational infrastructure. However, adopting this template also means accepting its architecture and predefined integrations: Next.js, Tailwind CSS, Prisma, Stripe/LemonSqueezy, Mailgun, and the included feedback/analytics integrations. If your project needs a radically different stack, custom database structure, or nonstandard integrations, you may need to refactor or remove parts — which can bring overhead. Also, as with many full‑featured boilerplates, you may end up with features you don’t need (blog, blog CMS, chat support, analytics) which adds extra complexity.

BoxyHQ SaaS Starter Kit is an open‑source boilerplate built with Next.js intended to give developers a ready‑to‑use foundation for building enterprise‑style SaaS applications. The kit uses a modern, commonly used stack: Next.js + React + Prisma (for database ORM) + PostgreSQL (for persistent storage) + Tailwind CSS (for styling) + TypeScript (for type safety and maintainability).

FastPocket is a boilerplate / starter‑kit for building web apps using PocketBase (as backend/database) paired with a modern frontend (Astro + React + TailwindCSS + daisyUI). It aims to give you a working foundation including authentication, payment integration, UI components, and deployment templates so you can move fast from idea to working app. FastPocket bundles support for payment processing via Stripe (one‑time and recurring payments) and ensures that your Stripe products synchronize with PocketBase which helps if you’re building a monetized web service. It also comes with a component library + theming (TailwindCSS + daisyUI) and pre-built UI components / layout structures (buttons, modals, cards, etc.), enabling rapid UI setup without designing everything from scratch. In addition, FastPocket provides documentation and deployment templates (for hosting backend and frontend), which lowers friction when going live. FastPocket fits developers or small teams who want to: start a web‑app or SaaS quickly, avoid spending time wiring auth, payments, backend, frontend, and instead focus on building the “real” product logic or features. Because it uses PocketBase, it can be a lightweight yet functional backend for small to medium‑sized apps. It also works well if you appreciate having an integrated stack (backend + payments + frontend + UI) that plays nicely together ideal for prototypes, MVPs, or first versions of a product.
