Hire expert Expo developers for your next project
Expo enables you to build performant, native-quality apps using just JavaScript—without worrying about native build tooling. We help teams design, develop, and ship reliable Expo apps, from MVPs to production-scale platforms.

Why you should build your next application with Expo
From faster iteration to easier builds, Expo equips your team with everything needed to deliver React Native apps quickly and reliably. It removes common setup bottlenecks, so you can focus on building features that matter.
Faster time to market
Expo’s managed workflow removes the native build complexity so you can focus on building features and shipping updates faster.

Everything you need to ship React Native apps, faster
Expo provides a powerful set of tools and libraries that simplify building, deploying, and scaling mobile apps. We help you use them effectively—so you can ship faster and with fewer surprises.
Expo Router
File-based routing with instant navigation—includes deep linking, universal links, and support for server-side rendering.
Expo DOM Components
Embed web-based React components directly inside native apps, bridging the gap between web and mobile without duplicating code.
Expo App Services
Automated mobile CI/CD with EAS Build, Submit, and Update—cloud builds, store submissions, and over-the-air updates, all integrated into a single delivery pipeline.
Expo Modules
Access native capabilities like sensors, haptics, camera, and filesystem through stable, well-tested libraries—no native code or wrappers required.
Expo Config Plugins
Customize native behavior without ejecting—automate changes to Info.plist, and more with maintainable, version-aware config plugins.
And more...
From asset bundling to push notifications, the Expo ecosystem covers core mobile needs out of the box—fully supported and optimized for production.

Use Expo DOM components to gradually migrate your web application to React Native
Expo DOM components let you use web-style components inside your React Native app. This opens the door to gradual migrations—one screen at a time—without rewriting everything from scratch.
- Start by rendering existing React DOM components within your Expo app
- Replace sections gradually with React Native code over time
- Use shared logic and UI across platforms without major changes
