About

Expo is the framework and cloud platform that takes React Native from a raw runtime into something you can actually ship on a deadline. The local tooling gives you a single CLI for iOS, Android, and web from one codebase, and EAS handles native builds, code signing, OTA updates, and store submissions in the cloud so you do not need a Mac to ship an iOS app. The free tier is generous enough to take real projects from prototype to App Store, and paid EAS plans cover teams that need more concurrent builds or priority queues.
