31SaaS vs Full Stack Kit

When choosing between 31SaaS and Full Stack Kit, 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 31SaaS?

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.

Developed by Said Hasyim, 31SaaS has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

What is Full Stack Kit?

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.

Created by Full Stack Kit, Full Stack Kit offers a robust foundation for building scalable SaaS applications.
