The React Native framework for iOS and Android apps
Expo is the official React Native framework, recommended by the React Native team at Meta. Build your app once, then ship it to iOS, Android, and the app stores from a single codebase.

Everything you need to build a React Native app
Expo covers the full lifecycle of a React Native app: agents writing code, building for iOS and Android, and shipping to your users.
Native code without a native project
Write custom native modules with the Expo Modules API and config plugins. Add the native functionality your app needs without hand-editing Xcode projects or Gradle files.
iOS builds without a Mac
EAS Build compiles signed iOS and Android binaries in the cloud on M4 Pro hardware. Ship from Windows, Linux, or macOS, no Mac required.
Ship your React Native mobile app
Submit finished builds to the App Store and Play Store with EAS Submit, or push instant updates to your users with EAS Update.
Built for React Native development, not bolted on
From solo developers to teams running thousands of builds a month, Expo is the standard way to build a React Native app, not an optional add-on.
No more ejecting
Continuous Native Generation regenerates your ios and android folders from config on every build, so you can upgrade React Native versions without untangling merge conflicts in native project files.
100+ modules, one SDK
Camera, notifications, maps, and more ship as part of the Expo SDK, tested against every new React Native release before you run npx expo install.
CI/CD built for React Native
EAS Workflows runs builds, tests, and store submissions from a git push, on infrastructure built for iOS and Android, not generic CI with Fastlane bolted on.
Routing that matches your file system
Expo Router turns your file structure into navigation for iOS, Android, and web, so you write one set of screens instead of separate navigators per platform.
Trusted by React Native teams
From indie developers to enterprise, teams like HipCamp, PrizePicks, and InfiniteRed build their React Native apps on Expo.
“Expo Workflows replaced our sluggish and brittle build process with something quick and dependable. Expo allows our engineers to focus on building features and not debugging build logs.”
“Setting up React Native CI/CD used to be difficult until I started using workflows. Expo was already the best way to write React Native apps. Now it’s the best way to test and deploy them as well.”
“Workflows allowed us to replace large complex yaml files with pre-built jobs fully leveraging the power of EAS. It's made our pipelines feel effortless.”
Rolling out app store submissions across your organization?
EAS Submit plugs into EAS Workflows so every team submits to App Store Connect and Google Play Console the same way, with the same signing, release tracks, and audit trail. No engineer uploading builds through Transporter by hand, and no submission process that only one person on the team understands.
Enterprise-ready out of the box
Security and compliance your procurement and legal teams can approve on day one.
SOC 2 Type II
Independently audited security controls. Full report available under NDA for enterprise customers.
GDPR & CCPA compliant
Data privacy frameworks already in place. Data processing agreement available for enterprise contracts.
SSO & role-based access
SAML-based SSO and granular permissions so the right engineers have exactly the right access.
Audit logs
Exportable logs for all admin actions and full chain of custody for every build and release.
99.9% uptime SLA
Enterprise SLA with dedicated support, because a failed pipeline the week of a release isn't acceptable.
