What is Expo?
Open-source toolkit to make iOS, Android and web apps from one codebase, with paid CI and hosting.
Who is Expo best for?
Expo is best for React Native developers who want cloud builds, store submission and live updates.
One codebase for every platform
React Native with the Expo SDK targets iOS, Android and the web, and the framework itself is free under MIT.
Builds and store submission
Expo Build compiles Android and iOS binaries on Expo's servers, and Expo Submit sends them to Google Play and the App Store.
Shipping fixes to installed apps
Expo Update sends over-the-air updates with bug fixes, priced by the monthly active users who download them.
Mobile CI/CD
Workflows chain builds, Maestro end-to-end tests and submissions, and Observe tracks launch times and errors after release.
How much does Expo cost?
Expo's framework is free and open source; its cloud services have a free plan with 15 Android and 15 iOS builds, and paid plans start at $19 a month plus usage.
