Why do enterprises need a React Native framework tailored to their needs?

In this webinar, Callstack's CTO Mike Grabowski and Principal Engineer Michał Pierzchała introduce the [Rock](https://www.callstack.com/open-source/rock), a developer-first toolkit that solves common challenges faced by large teams using React Native at scale. Whether you’re struggling with long CI build times, complex native integrations, or slow adoption across platforms, this session walks you through real-world solutions built for teams like yours. You'll see how our framework improves DX, speeds up delivery, and reduces waste across your CI/CD process without locking you into third-party cloud platforms.

## What you’ll learn about Rock

- How to avoid unnecessary native builds with built-in remote caching
- How to use the new CLI for faster local dev and better DX
- How to add React Native to existing native apps (Brownfield)
- How to support multiple platforms with modular config
- What makes this framework flexible for white-label, super apps, and more

This recording includes live demos, Q&A, and real feedback from early adopters.
