ShipFlutter
Multi-platform Flutter starter with Firebase, Vertex AI and built-in monetization

- Best for
- Developers who want one Flutter codebase shipping to Android, iOS and Web with Firebase, monetization, and AI chat already wired.
- Skip if
- You want an open-source starter to fork freely - ShipFlutter's license lets you own the code but prohibits derivative works or resale.
ShipFlutter, built by ex-Google engineer Marcel Pinto (pibi.studio), is a paid Flutter starter kit for shipping Android, iOS and Web apps from one codebase. It wires up Firebase auth (email + social), a real-time database, RevenueCat/LemonSqueezy payments, push notifications, analytics and crash reporting, plus Vertex AI-powered chatbot capabilities and an Astro-based landing page builder.
Pros
- True multi-platform target - Android, iOS and Web from a single Flutter codebase
- Built by an experienced ex-Google mobile engineer with a real production track record
- Vertex AI integration for chatbot features is a differentiator versus generic Flutter starters
Cons
- Proprietary license restricts derivative works and resale, unlike most MIT-licensed competitors
- Firebase-only backend, no Supabase or self-hosted alternative offered
- Annual subscription pricing ($99/yr) unless paying more for the lifetime tier
