AI coding agents can generate React Native code quickly, but they still need a reliable way to see, touch, debug, and verify the app they are changing. This talk introduces Agent Device, Callstack’s agent-native automation layer for mobile apps, and shows how it gives coding agents a practical feedback loop on iOS, Android, TV, and desktop targets.

We’ll look at what that means in practice: how agents inspect the UI, interact with the app, collect evidence, profile React Native behavior, and turn exploratory work into replayable checks. Then we’ll show practical workflows for React Native teams: letting an agent implement and verify a feature, debugging a broken screen, turning exploratory QA into deterministic checks, and supporting AI-assisted migrations where implementation and testing feed into each other.

The goal is to show how agent-assisted coding changes when the agent can work against the real app, not just the source code.

Module Federation lets you organize code into federated modules, dynamically loaded at runtime within a host application—a core mechanism behind Super Apps. On the web, this is typically handled with Webpack.Now, with Re.Pack as a Metro alternative, React Native supports it too. This allows existing native Super Apps to transition to React Native and enables truly cross-platform modules, letting developers use React and JavaScript without concern for where modules run.In this talk, we’ll explore these possibilities, best practices and real-world examples to help you build efficient, cross-platform Super Apps.
