Best Boilerplates with Landing Page

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.

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.

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.

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.

Full‑Stack Kit is a paid full‑stack boilerplate / template for modern web apps, built around Next.js (version 15), TypeScript, Prisma (with PostgreSQL by default, but supporting other databases), and Tailwind CSS (or comparable styling). The template aims to provide a ready‑to‑go foundation so developers don’t have to implement common boilerplate features from scratch. Full‑Stack Kit bundles typical “standard web application infrastructure”: authentication (email/password, OAuth, magic‑link), role‑based authorization, a built-in admin panel for user and content/announcement management, billing/subscriptions via Stripe (with subscription management, invoices), multi-language support (internationalization), landing‑pages/templates, user dashboards, and a set of UI/layout components for marketing pages, dashboards, and more. It’s positioned as a “launch‑fast” boilerplate: you get a structured, clean, extendable codebase with authentication, billing, UI scaffolding, admin & user management, which lets you focus on crafting the unique parts of your product rather than reinventing the foundation.

Gravity is a full‑stack boilerplate for JavaScript/TypeScript projects combining a Node.js backend with a React (or React Native) frontend designed to give developers a head‑start when building SaaS applications. It aims to deliver a working foundation so that you don’t need to assemble all the plumbing (auth, billing, database, UI, API) from scratch. The boilerplate includes support for multiple databases (like Postgres, MySQL, MongoDB, MariaDB and possibly others) which gives flexibility depending on your data/storage preferences. There is also a full “stack” support: server (Node.js + Express/API backend), web client (React + Tailwind or similar), and optionally native mobile clients (via React Native), which helps if you want a unified codebase for web + mobile. Beyond the core stack, Gravity claims to bundle SaaS‑ready features: authentication (email/password, magic links, social logins, 2FA, account security), subscription & billing support (with free plans, trials, seat‑based or usage billing), and a library of UI components & views (dashboard, admin tools, layout components, responsive UI, dark mode, etc.). Gravity also offers a “website/landing page template” (built with a static‑site generator + modern site tooling) useful for marketing, landing pages, pricing pages, etc. — thereby giving you both the “app core” and “public‑facing site” foundation.

Indie Starter is a boilerplate / starter‑kit built on a modern web stack (Next.js + React + TypeScript + Tailwind CSS + shadcn/ui) that aims to offer a clean, minimal yet ready‑for‑production foundation for SaaS or web applications. The boilerplate integrates backend/infrastructure services via Supabase (for database & auth) plus support for payments via Stripe for subscription or monetization flows. Indie Starter is structured to provide essential building blocks: authentication (including social logins, magic links, email/password), responsive UI components & layouts, a clean project architecture, type-safe configuration (via TypeScript + validation via Zod), and built-in SEO & content‑management setup (blog/landing page templates, metadata, etc.). Indie Starter makes sense for developers, indie makers, small teams or early‑stage founders who want to get a web app or SaaS up quickly without rewriting common infrastructure: auth, UI, payments, content, etc. It’s also suitable when you want type safety, modern stack, and clean architecture giving you a professional and maintainable starting point.

LaunchFast is a boilerplate designed to give developers a solid starting point for building modern web applications. It comes with pre-configured templates for frameworks like Next.js, Astro, and SvelteKit, providing authentication, database connections, payment integration, email support, analytics, and content management all set up and ready to go. The goal is to remove repetitive setup work so developers can focus on building the unique parts of their app. LaunchFast also includes SEO-friendly routing, page templates, and a basic UI scaffold, making it easier to launch functional web apps or SaaS projects quickly. While it speeds up initial development, adopting LaunchFast means following its chosen stack and architecture, so projects that require a highly customized setup may need adjustments or modifications to the default structure.
