The Flutter boilerplate that saves you 3 months of development
Stop building authentication, subscriptions, notifications, and onboarding from scratch. This Flutter boilerplate gives you production-ready code with a CLI that auto-configures your backend in one command.
What is a Flutter boilerplate?
A Flutter boilerplate is a pre-built codebase that provides the common features every mobile app needs: authentication, navigation, state management, API integration, and project structure. Instead of spending weeks writing code that has nothing to do with your actual product, you start with a tested foundation and focus on what makes your app unique.
ApparenceKit goes further than a typical boilerplate. It includes a CLI that auto-configures your backend (Firebase or Supabase), generates only the modules you need, and provides enterprise-grade architecture with 100% unit test coverage. It is the result of 6 years and 40+ apps shipped by the Apparence.io Flutter agency.

Don't take our word for granted, see what some of our apps have achieved
Hey, I'm Gautier.
After 7 years running a Flutter agency, I got tired of rebuilding the same things on every project.
ApparenceKit is the internal tool we built at Apparence.io — battle-tested across 40+ production apps.
Now I share it with you and keep improving it with the feedback of the community.
I also use it to build my own apps, like Kubbo habit tracker.

Why developers choose this Flutter boilerplate
Not a template — a code generator
Most boilerplates dump 50 files on you and say "good luck". ApparenceKit CLI generates only the modules you pick, configured for your backend. No dead code.
100% unit tested
Every module comes with unit tests. Not placeholder tests — real tests that cover edge cases. Learn testing best practices from production code.
Agency-tested architecture
Built by a Flutter agency with 15 developers and 40+ shipped apps. Clean three-layer architecture with Riverpod that scales from MVP to millions of users.
Backend auto-setup
The CLI creates your Firebase or Supabase project, enables services, downloads credentials, and connects everything. No manual configuration.
iOS, Android, and Web
One codebase for all platforms. The boilerplate handles platform-specific differences: push notification permissions, in-app purchase APIs, navigation patterns.
AI-ready cursor rules
Custom AI rules trained on the boilerplate's architecture. Cursor and other AI editors write code that follows the kit's patterns. Less fixing, more building.

Frequently Asked Questions
Creating an app is easy.
Creating a successful app is not.
- Most Flutter boilerplates give you a static project with pre-written code. ApparenceKit is a CLI-powered code generator that creates a project configured for your specific backend (Firebase or Supabase) with only the modules you need. No dead code, no manual wiring. Plus it comes with 100% unit test coverage and enterprise-grade architecture proven across 40+ production apps.
- Firebase is the easiest if you want zero backend management — Google handles everything. Supabase is better if you want an open-source alternative with a PostgreSQL database and more control. The boilerplate works identically with both. You can decide later — the clean architecture makes switching possible.
- Yes. The boilerplate is built and maintained by Apparence.io, a Flutter agency with 40+ apps shipped to the App Store and Google Play. It includes proper error handling, secure token storage, offline support, and CI/CD pipeline configurations. Companies like INRIA and Wolters Kluwer use it.
- Basic Flutter knowledge is helpful but not required. The boilerplate includes complete documentation, unit test examples, and a code architecture that teaches best practices as you use it. Beginners learn fast because the patterns are consistent across every module.
- The Solo license ($149) allows one app. The Professional license ($194) gives one developer unlimited apps. The Agency license ($520) covers 5 developers with unlimited apps and includes a web dashboard and live setup assistance.
- Authentication (email, social, phone), in-app subscriptions with RevenueCat, push notifications, onboarding, analytics (MixPanel/Firebase), error reporting (Sentry), internationalization, CI/CD templates (GitHub, GitLab, Codemagic), dark mode, remote config, Meta Pixel and Ads integration, and more. Pro plans include AI chat template and home widget generation.
- Yes. 10-day money-back guarantee, no questions asked. If the Flutter boilerplate doesn't meet your needs, reach out on Discord or Crisp chat.
- Yes. The boilerplate is actively maintained with regular updates for new Flutter versions, dependency updates, and new features. V5 was recently released with major improvements including AI cursor rules and home widget generation.
