Founders without a CTO
You have an app idea and you want to ship it. You can read code and follow instructions, but you don’t want to spend three weeks figuring out Apple’s provisioning profiles.
Introduction
Mosayic is a guided platform for building production-ready mobile apps. It is built for founders, indie hackers, and small teams who want to ship a real app to the App Store and Google Play — without becoming a cloud infrastructure expert first.
You sign in to the Mosayic dashboard, create a project, and follow a step-by-step guide. Mosayic scaffolds your codebase, wires up your accounts (GitHub, Google Cloud, Expo, Supabase), and helps you go from empty folder to working dev build on your phone.
What you get
Section titled “What you get”When you finish the setup guide, you own everything:
- A React Native + Expo mobile app, in its own GitHub repo
- A Python (FastAPI) backend API, in its own GitHub repo
- A Supabase project for auth, database, and storage
- A Google Cloud project for deploying the API to Cloud Run
- An Expo account for building and distributing your app
- A working dev build on your phone, talking to your local API
There is no “Mosayic platform” your app runs on. Mosayic is a workshop — once you’ve built the thing, you can walk away and Mosayic stops being load-bearing.
Who Mosayic is for
Section titled “Who Mosayic is for”Indie hackers
You ship things. You want a sane stack, a working CI/CD pipeline, and push notifications that actually work — without rebuilding all of it from scratch every time.
Small teams
You’re two or three people. You want production-grade infrastructure without paying for a dedicated DevOps engineer.
People building with AI
You’re using Claude Code, Cursor, or similar to write features. Mosayic gives the AI a real codebase, real services, and real deployments to work against — not a sandbox toy.
What Mosayic is not
Section titled “What Mosayic is not”- Not a no-code builder. You will edit code. AI assistants make this dramatically easier, but the source of truth is real React Native and real Python.
- Not a hosting platform. Your code lives in your GitHub. Your data lives in your Supabase. Your API runs on your Google Cloud. Mosayic owns none of it.
- Not a black box. Every command Mosayic runs is visible in your VS Code terminal. Every file it writes is yours to read and change.
