About Expo
What is Expo?
Expo is a full-stack React Native framework combined with cloud services (EAS) that helps developers build, deploy, update, and monitor native apps for iOS, Android, and the web—all from a single codebase. It eliminates the need for complex native configuration by providing a managed workflow with 100+ production-ready APIs.
Who is it for?
Expo is designed for solo developers, startups, and engineering teams who want to ship React Native mobile apps faster without sacrificing native performance. It's ideal for mobile app developers, indie makers, and product teams. It is less suited for teams that require total low-level native control (if you need custom native modules that aren't supported, you may need to eject to bare workflow).
Key use cases
Use Expo to build and distribute cross-platform apps—from prototypes to production—with OTA updates via Expo Update, automated CI/CD with Workflows, and built-in monitoring with Observe. Trusted by 100K+ active developers, 80% of the React Native community chooses Expo.
Key features
- Expo SDK — 100+ production-ready APIs for camera, location, notifications, and more, one install away.
- OTA Updates (Expo Update) — Push instant over-the-air updates to every user without going through app store review.
- CI/CD Workflows — Automate builds, tests, and releases for Android, iOS, and web.
- Build & Submit — Build native binaries in the cloud and submit directly to app stores with Launch.
- Observe — Built-in monitoring and observability to track performance metrics and spot regressions.
- Expo Go — Test and iterate on real devices instantly with the Expo Go mobile app, even on low-spec machines.
- MCP Server — AI-native tool for powering app development workflows with AI agents.
