# Tech Stack

> The technology behind apps built with CatDoes.

## React Native Expo

Every app built with CatDoes uses [React Native Expo](https://expo.dev/) under the hood. This gives you:

* **Cross-platform** — One codebase for iOS, Android, and web.
* **Native performance** — Your app uses native UI components, not a web wrapper.
* **Expo ecosystem** — Access to a rich set of libraries for camera, location, notifications, and more.

## What this means for you

* If you ever want to eject and continue development on your own, you have a standard React Native Expo project.
* Your app isn't locked into CatDoes — you own the code.
* Engineers on your team can extend the app using familiar React Native tooling.

<Note>
  You don't need to know React Native to use CatDoes. The AI handles all the code. But if you do, you can always dive into the source.
