01Open-source framework

Mobile App Framework: one codebase that ships as many branded apps.

The problem it solves

Companies that sell one app to many clients usually copy the code for each client, and the copies drift apart. This framework keeps a single React Native codebase and builds a separate branded iOS and Android app for each client from it.

  • React Native 0.86
  • Expo SDK 57
  • TypeScript strict
  • Redux Toolkit
  • GraphQL
  • zod
  • Jest
  • AI-agent ready

Live demo

Pick a brand and watch the same app change.

All three apps run the same screens and logic. Only the brand settings differ: name, store ID, colours, button shape, languages and features.

✦ AI-ready

Ready for AI, in the code and in the app.

  • For AI coding toolsThe build enforces the rules

    Layer and import rules run in CI. Code from Copilot, Cursor or Claude either fits the structure or fails the build.

  • For AI modelsTyped inputs and outputs

    TypeScript and zod schemas define exactly what a model can call, and reject bad output before it reaches the screen.

  • For app usersAn assistant that uses real features

    The in-app assistant calls the same actions as the buttons and asks before changing data. Each brand can switch it off.

What's included

Everything a team needs to ship.

  • White-labelA new client is a settings file

    Name, colours, languages and features. Screens and business logic stay shared.

  • ArchitectureStructure checked on every build

    Layer rules run in CI, so the code stays clean as people and AI tools add to it.

  • NetworkingNetwork errors handled safely

    Token refresh, retries and bad responses become clear errors the screen can show.

  • Design systemEvery brand stays readable

    Colour, type and shape settings for light and dark, with contrast checked before release.

  • LanguagesRight-to-left included

    Arabic, French and English run on the same screens. Layout flips for Arabic.

  • AI in the appAssistant uses the real features

    It calls the same logic as the interface and asks before changing any data.

02AI agents

AI agents that do real engineering work, with a person approving every change.

I build agents the way I build apps: every action is a typed, tested function, the rules live in code, and nothing is saved until a person approves it.

Featured agent

Brand Agent

Built and tested end to end · first live-model run next

You type one sentence about a new client. Brand Agent creates their version of the Mobile App Framework app (name, colours, languages and features) and runs every check. Then it stops and waits for a person to approve.

The AI decides what to do; plain code enforces the rules. It can only write inside the new client's folder, it has no way to commit code, and an approval covers only the exact files that passed the checks.

  • Action ran
  • Shortcut blocked
  • Waiting for a person

Replay of the end-to-end test. The AI's moves are scripted; every tool ran for real.

How I build agents

  • Tool useTyped, tested actions

    Every action an agent can take is a checked function with its own tests and permissions.

  • MCPConnected to your systems

    MCP servers give agents live access to repos, issue trackers, analytics and internal APIs.

  • OrchestrationLong tasks that can resume

    Planner, worker and reviewer steps with retries, budgets and checkpoints, so a long run picks up where it stopped.

  • Evals & guardrailsMeasured before release

    Tests on real tasks, traced runs, cost and speed limits, and approval before anything that can't be undone.
