Building blocks
for agentic workflows

  1. Build beautiful apps anywhere powered by Expo’s CLI, Skills, and MCP. Test on your device with Expo Go, validate with Simulators, distribute with Launch or Builds.

  2. Find what breaks before your users do. Cloud simulators and device infrastructure for your team and your agents. Workflows runs your test suites on every change, starting from ready-made templates.

  3. Deploy to TestFlight and the app stores for native releases, Update for everything after, with channels and rollouts you control.

  4. See how the app behaves in production. Observe surfaces crash information, performance metrics, and Update adoption, and Update ships the fix if something breaks.

Expo is amazing

NicoDevs@Nico_Devs

I love @expo, it made React Native dev so much easier.

Firstly, it allows anyone to dev from any machine, even with very low specs and run the app on device with Expo Go app.

Also, it includes so many libraries and the performance is crazy especially on Expo SDK 54

Nana Asante@asantenocturnal

I love expo

Antonin marchard@antomarchard

The more time flies, the more I love @reactnative & @expo

Adrian Carolli@icookandcode

I love @expo for making my life so much easier!

Simon Grimm@schlimmson

It's almost shocking how much I take Expo API routes for granted at this point.

I can't imagine working any other way, they are a natural part of every RN project I do.

Hugo Duarte@hugoasduarte

I love @expo so much!

Was struggling to upgrade an old React Native app to the latest version for a few days without success.

Created a new expo app, copied my src folder along with some package installs and was ready in just a few minutes!

devon@devon_94

highly recommend @expo

JD Conley@wackie

if you're debating between raw react native and expo, choose expo. i tried years ago but it wasn't good enough. now the wrapper is winning. smooth dev environment. flexible. much better ecosystem and documentation.

Melih Yumak@hadnazzar

🌟 Why choose #Expo for your next app? Enjoy the simplicity of building with one codebase for all platforms, access a rich library of pre-built components, and streamline updates with over-the-air changes—all without touching native code! 🚀 #ReactNative #js #100DaysOfCode

:) waally@_mohawwal

I love expo/react native

Josh Gonsalves@joshgonsalves_

Makes sense. I do LOVE expo.

miaugladiator11@miaugladiator1

can 100% recommend expo is so much better than just pure react native imo

Dane Grant@danecando

Also, @expo is amazing

getDerivedSwaggerFromHacker@hackerswagger

Big enterprise app guy here. Expo is the best! In the time another team experimented with all the new repack module federation nonsense I've got our two apps using expo CNG and almost done with new architecture. We have a mini app architecture and it's a pain.

Prince Ajuzie@princeajuzie7

dude, react native + expo is the best option out there.

Patrick Aljord@patcito

Just use @expo
