#What is MVP-Boilerplate?

MVP-Boilerplate is an open-source production starter kit tailored for indie developers and non-technical founders building cross-platform MVPs that need to go from idea to launch lightning-fast, without piecing together fragmented tools. Its core value lies in providing a battle-tested, all-in-one foundation that handles authentication, payments, analytics, and deployment out of the box, so you can focus on your unique features and user validation rather than infrastructure drudgery. Powered by Flutter for seamless mobile/web/desktop experiences, Supabase for scalable backends, and modern JS tools for web landing pages, it's ideal for use-cases like subscription-based SaaS tools, productivity apps, e-learning platforms, or any early-stage startup requiring quick iterations, monetization, and real-user insights.

#Features ⚡

• Cross-Platform Flutter App: Build once for iOS, Android, web, and desktop with Riverpod state management and GoRouter navigation—includes dark mode support and responsive layouts.

• Supabase Backend Integration: Effortless auth setup with email/password and SSO (Google, GitHub), plus local dev config, row-level security, and Deno-based edge functions for custom logic.

• Stripe Payments Module: Handle one-time purchases and subscriptions seamlessly, with webhooks syncing data to Supabase, customer ID storage, and pre-built screens for checkouts and billing portals.

• PostHog Analytics: Track key events like sign-ups, logins, checkouts, and account deletions across frontend (iOS/Android/web/Mac) and backend, unified by user_id for actionable insights.

• Postmark Email System: Send transactional emails with DKIM/DMARC/SPF for deliverability, plus templating for easy customization—avoids spam filters right from setup.

• GitHub Actions Pipeline: Automate PR previews on Netlify, semantic versioning bumps, and deployments to Netlify/Supabase—mobile publishing in progress for even smoother releases.

• TypeScript Web Landing Page: Quick-start app router setup with Supabase auth and Stripe, perfect for marketing sites or PWAs that tie into your Flutter core.

#Pros ✅

• Saves hundreds of dev hours with production-grade integrations that just work, accelerating MVP launches

• Cross-platform consistency reduces maintenance overhead for multi-device apps

• Strong community backing via Discord and frequent updates ensure reliability and fresh features

• No vendor lock-in: MIT-licensed code is fully customizable and extensible

• Built-in analytics and payments enable immediate monetization testing without extra setup

#Cons ⚠️

• Relies heavily on Flutter ecosystem, which might require a learning curve if you're JS/React-native only

• Some advanced features like Sentry monitoring and full mobile automation are still in progress (marked 🚧)

• Assumes familiarity with Supabase/Stripe; pure beginners may need the linked docs for initial hurdles

#Included Components - Templates

• Email Templates: Postmark message streams with verification/welcome/onboarding flows, plus DNS setup scripts for custom domains.

• CI/CD Workflows: GitHub Actions YAMLs for Netlify previews, version bumping, Supabase function deploys, and PR validations.
