About

Expo lets developers write apps that are written in JavaScript and run natively on Android, iOS, and the web. Our cloud services that work with all Expo and React Native apps, named Expo Application Services (EAS), further speeds up teams by helping them get to the app stores as fast as possible and continue growing. We believe that mobile apps provide a better experience than websites, but making apps is much more difficult than it needs to be. With Expo, we're bringing together the best of the web, like its development speed, fast iteration cycles, easy deploys, and automatic cross-platform support, and the performance, device capabilities, and user experience of native apps.

Expo is a full-stack React Native framework with cloud services that enables fast development and deployment of native apps for iOS, Android, and the web. It emphasizes a single codebase, over-the-air updates, and a suite of tools and libraries to accelerate app lifecycle from development to deployment.

Expo provides a React Native-based development framework plus cloud services: start on-device with Expo Go, write apps using React and native code when needed, build and submit to app stores via automated workflows, and deploy over-the-air updates. Key capabilities include a large set of production-ready libraries, native modules via Expo Modules API and config plugins, OTA updates, build automation, hosting, monitoring, and analytics. The platform supports building for multiple platforms from a single codebase and offers hosting, CI/CD workflows, and performance/observability insights after releases.

Who it’s for: Developers and teams building mobile apps (indie to enterprise) who want to ship React Native apps quickly across iOS, Android, and the web with integrated cloud services.
