ApparenceKit vs NextJet

When choosing between ApparenceKit and NextJet, 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 ApparenceKit?

ApparenceKit is a template generator for Flutter, created by a team with years of Flutter-app experience. On the surface, it’s pitched as a way to bypass many of the repetitive, boilerplate tasks that come with building a mobile (or web) app from scratch: authentication, user flows, payments/subscriptions, push notifications, onboarding, i18n (multilanguage), analytics, theming, and more. When you use ApparenceKit, you start your project by running a CLI that scaffolds a full Flutter app wired up with a backend option (you can choose between Firebase, Supabase or a custom REST API), pre-built modules for auth, subscriptions, notifications, and navigation, plus optional modules such as feedback/voting, translations, remote config, and more. This means that instead of spending weeks setting up the basics of your app (login logic, paywalls, push-notifications, internationalization, UI navigation, etc.), you get a “ready-to-go” foundation that you can build on immediately. For many simple or medium-complexity apps (MVPs, prototypes, early-stage mobile products), that can be a significant time-saver.

Developed by Apparence, ApparenceKit has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

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.
