ApparenceKit vs Rockstack

When choosing between ApparenceKit and Rockstack, 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 Rockstack?

This boilerplate is a comprehensive solution for building SaaS applications, featuring three main sections essential for any app: Public Pages (like Landing, Login, Contact), Admin (/admin for Dashboard, Users, Settings), and App (/app/:tenant for tenant-specific dashboards). It leverages a next-generation Node.js and TypeScript ORM with a Repository Pattern for efficient data management. The platform supports flexible payment models through Stripe, including flat-rate, user-based, and one-time fees.

Including Next.js, Remix, or SvelteKit and intended to give you a ready-to-go foundation for building subscription‑based, multi‑tenant web applications. With RockStack you get a basic SaaS “shell” that includes core needed parts: built‑in email/password authentication and user management (without requiring external auth libraries), tenant/organization support so different customers/users can live under separate “workspaces,” subscription and payment flows (flat‑rate, one‑time, per‑seat or usage-based) via Stripe, and support for roles & permissions to help manage access control.

The kit provides a UI + layout foundation: a public “marketing / landing” section (for pages like landing page, pricing, contact, login), an admin dashboard area (for app owners), and the application dashboard area (for tenants/users) so both the public‑facing site and internal user/admin interfaces are ready.
