I became a T3 Code user recently - it’s great especially if you have many subs and many machines to manage. I recommend giving it a shot if you haven’t already 👏. I also like in-app simulator preview experience support powered by @expo device hub (for streaming) and @agent_device (for agentic control) 😎
T3 Code now has a device hub to let you and your agent see and manage iOS and Android simulators while working! One of the coolest things (I think) is that the simulator doesn't even have to run on your device! You can setup remote hosts to let agents running on Linux boxes trivially test iOS changes on a Mac Mini! Still early but wanted it out there, lmk any feedback! Available now on nightly!

Any agent can test iPhone Duo apps for you now. No need to do it by hand. Folded, half-open, open, all without stealing your focus or other agents sessions. Just give them @agent_device

playing around with @eve, spun up a little Mobile Agents Index. compares tools like @agent_device, Argent from @swmansion, @Baconbrix’s serve-sim, and more fully autonomous, run by @vercel’s Eve mobileagents.dev

e2e + agent device 📱 I ported React Native Pager View's test suite from Maestro to e2e (a new testing framework I'm building) and... It's 2x faster. we are still iterating on it, but it's very promising.

Thanks for agent-device! So far much better than the Codex plugin I’ve been rocking before

T3 Code (Nightly) device panel is pretty cool. Agent clicks around the app, and I can throw modifiers like dark mode and inspect a11y tree. A bit laggy when recording the demo, smooth otherwise. Thanks @jullerino for shipping this

what will you ship with agent-device as a building block?
Releasing free unlimited React Native cloud Simulators An OSS CLI that hosts simulators on Github and lets you or your agent run @agent_device to test things out. Available for private repos too. Try out the alpha today at reactnativefeel.com/sim or install right away w/ `npm i -g native-sim`

aha, that's why when I disabled both of them, it used maestro instead. good finding, I think maestro is the slowest one to use. for anyone interested I think using it with agent-device would be good way to do because @agent_device is indeed one of the fastest tool to query your device.

Introducing: 𝚜𝚌𝚛𝚎𝚎𝚗𝚜𝚑𝚘𝚝 --𝚌𝚛𝚘𝚙-𝚘𝚗. Agents can capture just the component they’re verifying, not the whole screen. Isolated visual checks. Fewer tokens. Clearer diffs. Coming to @agent_device 0.21 🔜

Mobile development agents need to verify their work on real iOS simulators and Android emulators to perform well. But local simulators alone won’t scale. Background agents, CI, and parallel agent workflows all need on-demand simulator access too. That’s why we’re building EAS Simulator. expo.dev/services/simulators
You can’t create a software factory without a verification loop. If even one platform is left behind, your overall velocity is at jeopardy

Connect to Expo Simulators with agent-device ⬇️
Just tried @expo Simulators in the browser and it actually changes how you develop apps. No Xcode, no setup, no waiting. Run your app on a real iOS simulator from anywhere. Thank you @expo for building this, and thank you @joe_d_ryan for giving me the chance to try it. 🙏 #ReactNative #OpenSource #expo

2× faster with @agent_device 🔥 @maestro, now it is your move to make mobile E2E faster
YAML e2e tests already feel passé 😬 @agent_device makes mobile e2e testing quick, affordable, and far less painful Thanks for building a better way to test 💪
