Dirstarter
Dirstarter
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.

Makerkit
Makerkit
MakerKit is a SaaS‑starter boilerplate built for modern React/Next.js (also supporting Remix/Supabase or Firebase variants) that tries to give you a production‑ready foundation, rather than a barebones template. At its core MakerKit bundles authentication (email, social login, magic‑link, optional MFA), user and team/organization management (multi‑tenancy, roles, invitations), and subscription/billing support via payment providers (Stripe or Lemon Squeezy). The boilerplate comes styled by default using a modern UI stack with Tailwind CSS (and Shadcn/Radix‑based UI components), with light/dark mode and includes UI scaffolding for dashboards, admin panels, marketing pages, blog/documentation pages, and a customizable layout structure. MakerKit aims to reduce the time and effort needed to ship a SaaS: instead of wiring up auth, payments, data layer, UI and common SaaS flows from scratch, you get a working skeleton that you can extend, customize, and build on. This includes also support for serverless or traditional hosting setups, built‑in support for sending stylized transactional emails, and optional plugins/features (like documentation/blog generation, admin dashboards, analytics hooks, and more) to help bootstrap both the product and its public-facing/marketing side.

Bedrock
Bedrock
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.

Cascade
Cascade
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.

Gravity
Gravity
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.
