🪨 Rock is a modular toolkit for teams building React Native apps. It helps improve build times and developer experience while fitting into your existing workflows and infrastructure.

Key Features

☁️ Remote Build Cache
Save up to 96% of build time by reusing native artifacts (APK, AAB, APP, IPA) across machines and CI. Use built‑in integrations for GitHub, S3, and R2 or bring your own storage.

🔗 Brownfield ready
Add React Native to existing iOS and Android apps using Rock Brownfield.

🔌 Modular & Extensible
A plugin‑driven architecture that lets you customize platforms, bundlers, cache providers, and more.

🖥️ Cross‑platform‑ready
iOS and Android by default; designed to extend to TVs, macOS, and Windows (coming soon).

⚡ Easy Community CLI Migration
A familiar CLI that helps you develop, run, and build your app. Migrate from Community CLI in minutes.
