NextJet vs ProtonStack

When choosing between NextJet and ProtonStack, it's essential to understand the key differences that make each boilerplate unique. Both are excellent choices for building SaaS applications, but they cater to different needs and development approaches.

What is NextJet?

NextJet is a full‑stack SaaS boilerplate built with Next.js, TypeScript and modern web‑app tooling, made to give developers a solid, production‑ready foundation when building subscription‑based or SaaS‑style applications. Out of the box it handles core infrastructure: user authentication + authorization (including OAuth and magic‑link support), payment/subscription logic via Stripe or Lemon Squeezy, and pre‑built user dashboards + admin panel. It also includes content‑management and marketing‑side features: a blog and documentation system using MDX, a customizable landing/marketing site, email templates, and onboarding flows. The project follows a modular, maintainable architecture (monorepo via Turborepo, clean folder structure, typesafety via TypeScript), which helps keep code organized, useful if you plan to grow or scale the app over time. Because much of the “plumbing” is already configured, you can skip repetitive setup and get to building your product‑specific logic faster. At the same time, using NextJet means trusting its built‑in architecture, tech stack and conventions. If your project needs a very different stack, unusual backend/data requirements or a minimal footprint, you might need to refactor or drop parts of what comes with the boilerplate.

Developed by Renas Hassan, NextJet has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

What is ProtonStack?

ProtonStack is a full‑stack boilerplate built with Next.js + React + TypeScript + Tailwind CSS, designed to give developers a ready‑made foundation for SaaS and web applications. Out of the box, ProtonStack includes a production‑ready authentication and user‑management system via Clerk.dev, database integration through Prisma (with support for various databases, including Postgres, MySQL, or scalable services like PlanetScale or Supabase), subscription and payment workflows via Stripe, multitenancy (organizations/teams support), plus a UI kit built with component libraries like Shadcn UI / Radix UI. ProtonStack also provides strong developer tooling: linting/formatting (ESLint, Prettier), commit‑hooks (with Husky), schema validation (via Zod), unit and end‑to‑end testing setup (with Jest, React Testing Library, and Cypress), plus built-in support for a blog or documentation using MDX useful for marketing or public‑facing content.
