What if you could skip most of your mobile app’s native builds, without cutting corners? In this episode of _React Universe On Air_, we discuss a framework that’s transforming how large-scale teams develop with React Native. Spoiler alert: it cut native build times from 35 minutes to under 4 on one enterprise project.

## Real teams, real pain points, real results

Host Ola Desmurs-Linczewska talks to Michał Pierzchała, Principal Engineer at Callstack and the driving force behind [Rock](https://www.callstack.com/open-source/rock). Alongside him is Łukasz Chludziński, who tested the framework hands-on in a real enterprise project. Together, they unpack how Rock was created, why it exists, and how it’s helping large teams streamline their pipelines and ship faster with confidence.

## How Rock tackles real enterprise problems

Built for apps too complex for Expo and too custom for basic React Native CLI setups, Rock offers modular tooling tailored for teams juggling monorepos, branded variants, and legacy code. In this episode, the team shares how it’s already being adopted incrementally in production environments and the kind of results it delivers.

Here’s what they break down:

- **Build times slashed**: One project’s test pipeline dropped from ~35 minutes to 3–4 minutes thanks to native build caching.
- **CI-native caching**: Smart fingerprinting detects whether a native build is needed, saving compute time and unblocking PRs.
- **Incremental adoption**: Rock can be added to just one pipeline at first—no need for full migration.
- **Modular, plugin-based design**: Works with Metro, Re.Pack, GitHub Actions, and more—custom setups are welcome.
- **Brownfield integration made easy**: Use iOS and Android plugins to drop compiled React Native bundles into existing native apps without CocoaPods or Gradle rewrites.
- **Improved dev/QA collaboration**: Developers and QA engineers can download prebuilt artifacts and skip local builds altogether.

Michał also reflects on the framework’s roadmap, from its CLI-first interface to eventual support for TV platforms, desktop targets, and becoming a recognized official React Native framework alongside Expo.
