ApparenceKit vs Solid

When choosing between ApparenceKit and Solid, 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 Solid?

Solid is a SaaS‑oriented boilerplate / starter kit built on Next.js + React + TypeScript, designed to furnish most of the foundational pieces a modern web/SaaS project needs from frontend and backend structure to authentication, payments, content and UI components. Solid comes bundled with a wide range of features useful for SaaS or web‑app development: secure user authentication via NextAuth (supporting social login, magic‑link, password reset, etc.), database integration (designed to work with relational DB like PostgreSQL, via ORM or your preferred provider), subscription/payment support through Stripe, and blog/content support via a CMS (for instance Sanity for blog management), enabling dynamic content and documentation out-of-the-box. On the front‑end side, Solid offers a comprehensive UI kit and pre-made pages: landing page templates, pricing and business pages, blog lists and post pages, documentation pages (via MDX), auth flows pages, and responsive design with modern styling. It also includes performance & SEO optimizations, dark‑mode support, search integration (via Algolia for search), transactional email support, newsletter integration (e.g. via Mailchimp), and a collection of reusable UI components based on modern best practices, which can speed up development while maintaining code quality and scalability.
