Expo is an open-source framework and toolchain for building universal native apps with React and React Native, targeting Android, iOS, and the web from a single codebase. It includes SDK libraries, a file-based router, the EAS build/deploy CLI, and managed workflows for development, testing, and release.
Use cases
- build a react native app for ios and android from one codebase
- create a cross-platform mobile app that also runs on the web
- set up over-the-air updates and app store builds without managing xcode and android studio
- scaffold a new react native project quickly
- add file-based routing and navigation to a react native app
- build and submit mobile apps to app stores from ci
When to choose
- you want a single TypeScript/React codebase for Android, iOS, and web
- you prefer managed tooling for builds, updates, and deployment
- your team is new to native mobile development
- you need rapid iteration with hot reload and cloud builds
When to avoid
- you need deep custom native code or niche native modules not supported by the SDK
- you are building a non-React app or a pure native Swift/Kotlin project
- you require minimal app size and cannot tolerate the Expo runtime
- you need fine-grained control over every native build configuration
