Expo is the leading open-source platform for building cross platform mobile apps. As of May 2026 Expo averages more than 4 million weekly downloads and is used by millions of developers all over the world. Founded in 2013 and based in San Francisco, Expo provides a complete development platform that covers the full mobile app lifecycle: from writing code with Expo Router and the Expo SDK (100+ maintained libraries), to building in the cloud with EAS Build, pushing over-the-air updates with EAS Update, submitting to the App Store and Play Store with EAS Submit, and automating mobile CI/CD pipelines with EAS Workflows. Expo eliminates the hardest parts of mobile development. Cloud builds run on dedicated M4 Pro hardware without requiring local Xcode or Android Studio setup. OTA updates let teams push JavaScript changes to production in minutes without app store review. EAS Workflows automates builds, tests, and deployments with mobile-optimized CI/CD that runs 2-3x faster than generic CI providers. Teams use Expo to ship production apps faster with less infrastructure overhead. The platform handles iOS and Android code signing, app store credentials, build configuration, and deployment automation so developers can focus on building features. Expo supports apps of any size, from solo developer side projects to enterprise teams shipping apps used by millions.
