About Builder
We believe anyone should be able to ship an app
Builder is your AI Flutter engineer — turning plain-language ideas into real, store-ready mobile apps, without a dev team.
Our mission
For most people with a great app idea, the path to shipping is blocked by cost, complexity, and time. Hiring a mobile team is expensive; learning Flutter, Gradle, signing, and store submissions takes months. We started Builder to remove that wall.
Builder acts as an AI Flutter engineer: you describe the app you want in plain language, watch it come to life in a live preview, and export the real, signed artifacts you need to launch on Google Play and the App Store. No lock-in, no proprietary format — just genuine Flutter & Dart you own.
What makes Builder different
Plenty of "app builders" hand you a pretty mock-up and trap you in their platform. Builder generates a real Flutter project and takes you all the way to the store-ready outputs that actually get an app live. That difference — real code plus real shipping — is the whole point.
What we value
Principles that shape the product
You own your work
No proprietary format, no lock-in. Export the full source anytime and keep building in any IDE. Your app is yours.
All the way to the store
Most builders stop at a preview. We take you to the signed APK, the Play-ready AAB, and the keystore that actually ship an app.
Trust by default
Secure authentication, careful handling of signing keys, and transparency about how your data and code are used.
