Framework

Overview

Expo is a full-stack React Native framework designed to accelerate app development across iOS, Android, and the web from a single codebase. It combines the Expo SDK (100+ production APIs), the Expo CLI, and Expo Application Services (EAS)—a suite of cloud tools for building, submitting, updating, and monitoring apps.

The platform is trusted by over 3 million developers and powers thousands of production apps. It eliminates the need to write native code while providing access to native capabilities, making it accessible to developers of all experience levels. Expo handles the complexity of app distribution, offering features like over-the-air updates, automated CI/CD workflows, app store submission, and built-in observability.
