## What it is
A React Native library providing over-the-air (OTA) hot update capabilities with tiny bsdiff/hdiff-based update packages optimized for Hermes bytecode. It includes a global delivery service, web dashboard with analytics and staged rollouts, CLI tools, and crash rollback safety mechanisms.

## Use cases
- push hotfixes to react native apps without app store review
- ship over-the-air updates for react native
- roll out staged percentage-based releases to mobile users
- automatically roll back a broken react native update
- reduce update download size with hermes bytecode diffs
- monitor update success rates and version distribution
- debug why a device did not receive an ota update

## When to choose
- you need fast OTA updates for React Native apps with minimal package sizes
- you want staged rollouts, analytics, and crash rollback built in
- your app uses Hermes bytecode or the React Native new architecture
- you need native-side recovery even when JS fails to boot

## When to avoid
- you target Android RN 0.73.0–0.76.0 with the new architecture (unsupported due to upstream issues)
- you need fully self-hosted infrastructure without a paid or global service
- your app is not React Native
- you require a permissive open-source license (license is non-standard)
