FEATURES · BUILDING
Real apps. Not prototypes.
Auth, payments, dark mode, offline, analytics: ready to use. Not a demo. Your app code is yours, in a GitHub repository on a standard React Native + Expo + Supabase stack.
HOW A BUILD WORKS
Four steps. The first two are deterministic. The third uses automated agents. The fourth catches mistakes.
Most of your app rests on a ready-made, tested foundation. Automated agents write the part that makes it yours: onboarding flows, feature screens, services, types, and database migrations. Quality gates verify the build compiles, routes resolve, config is valid, and the must-have features on your screens are checked against the code before the build is sealed.
proven foundations · everything a real app needs, already built
Start
The build engine starts from proven foundations. Auth, payments, theming, analytics, offline sync, navigation. All pre-wired.
Configure
A master config is generated deterministically from the architecture spec. App identity, design tokens, feature flags, navigation structure, backend schema. Goodspeed provisions that backend as part of the build, so you open no infrastructure accounts.
Generate
Automated agents write only what is unique to your app: onboarding flows, feature screens, services, types, and database migrations.
Verify
Automated checks verify the build compiles, routes resolve, and config is valid. A human gate reviews the output before it moves to testing.
LIVE BUILD MERGE
Auth, payments, offline, analytics + your screens and services
THE APP YOU SHIP
A real app, not a clickable mockup
Native screens, real navigation, working data. This is what installs on a phone and goes to the store, generated on top of a ready-made foundation you own outright.
WHAT YOU CAN SHIP WITH
Everything a real app needs, already built
Auth, payments, offline sync, push, analytics, subscriptions, all pre-wired. Pick what your app needs, skip what it doesn't. The unglamorous infrastructure is already built and tested, so the build can focus on what makes your app different.
| Item | Description | Strength |
|---|---|---|
| Auth | Email, Google, Apple sign-in. Biometric lock. Session management. | Built in |
| Payments | Subscriptions, one-time purchases, paywalls. Fully integrated. | Built in |
| Theming | Dark and light mode. Custom color palette. Consistent styling. | Built in |
| Analytics | Event tracking, screen views, user properties. Privacy-first. | Built in |
| Offline | Offline queue with automatic sync. Works without internet. | Built in |
| Notifications | Push notifications. In-app notification center. Permission handling. | Built in |
| Navigation | File-based routing. Tab bar, stacks, modals. All pre-configured. | Built in |
| Error handling | Error boundaries, graceful fallbacks, crash reporting. | Built in |
| Testing | 20+ smoke tests. CI pipeline. Release script with gates. | Built in |
| Hosting | Goodspeed provisions the backend during the build (database, auth, analytics) and runs it after launch. Keeping a live app hosted and patched starts at $49 a month plus usage. | Run for you |
Your app code is yours. Every app gets its own GitHub repository on React Native, Expo, and Supabase. No vendor lock-in, and self-hosting stays available: export the full source and run it anywhere.
