Expo.dev

Full-stack React Native framework with cloud services covering development, build, deployment, and updates. Lets teams write one JavaScript or TypeScript codebase that runs natively on Android, iOS, and the web, with optional native modules in Kotlin or Swift when needed.

Expo is the native framework recommended by Meta and used by thousands of enterprises and startups. Around 80% of React Native developers adopt it, with 50,000+ Discord members and 500,000+ projects created. SOC 2 Type 2 and GDPR compliant, serving hundreds of millions of end users.

Key capabilities:

• 100+ production-ready SDK modules: camera, push notifications, deep links, and more
• EAS Build, Submit, and Update: cloud builds, app store submission, over-the-air updates without new store releases
• EAS Workflows for CI/CD: automate builds, tests, and releases from GitHub
• Expo Go for device development without local native tooling
• File-based routing with Expo Router, API routes, and config plugins for custom native code

Developers use Expo to ship universal apps from a single codebase, from indie projects to enterprise products. Teams skip Xcode and Android Studio for day-to-day development, rely on over-the-air updates for quick fixes, and integrate builds and submissions into existing GitHub workflows.
