Overview

Expo is a React Native framework and cloud service platform for building native apps for iOS, Android, and the web. The main product pages describe it as a full-stack framework with tools for development, deployment, updates, hosting, and monitoring.

It combines app development libraries with Expo Application Services (EAS), which cover builds, submissions, updates, hosting, workflows, and observability. The platform is aimed at developers who want a single React-based workflow for shipping and operating mobile and web apps.

Core capabilities

Cloud builds

Create Android and iOS builds in the cloud, with support for custom native code and build queues that vary by plan.

Store submission

Send builds to Google Play and the App Store from the cloud, with automatic submission options and formatted logs for review.

Live updates

Ship over-the-air updates for fixes, content changes, and beta features without waiting for a store release.

Web hosting

Host web apps and API routes in one command, with routing through Expo Router and usage metrics for deployed services.

Observability

Track app performance and release impact with built-in observability for user population, API and hosting requests, and error rates.

Workflow automation

Automate builds, submissions, updates, and release steps through configurable CI/CD workflows.

Common use cases

Independent app development
A solo developer can start with the free tier, create test builds, and use Expo Go or development builds to validate an app on real devices before paying for more capacity.
Team release workflow
A product team can use cloud builds, internal distribution, and store submission to move from development to release without stitching together separate release tools.
Web and API deployment
A web-first or full-stack team can use Expo Hosting to deploy a web app and API routes alongside a React Native client in one platform.
Rapid iteration
A team shipping frequent changes can send over-the-air updates for bug fixes, content edits, or beta features without waiting for each app store release.
Enterprise deployment
An enterprise team can adopt paid plans for higher build limits, SSO, custom environments, and security documentation as its app and compliance needs grow.
