@sagawrr fun fun!

New nitro modules in town

Fun building and optimizing this with iteration of @agent_device and nitro modules skills (https://t.co/byENqNU9rY)

@PrinceRadebe @thymikee Yup, even on 0.18.2

Fable 5 made every app relaunch in agent-device 6× faster.

𝚘𝚙𝚎𝚗 --𝚛𝚎𝚕𝚊𝚞𝚗𝚌𝚑: 12s → 2s

For an AI agent, that's 2.3x faster time-to-interaction. It's verifying and tapping in 5s instead of 13.

I gave Devin access to a remote iOS device on AWS Device Farm and… it just worked 🤯

Well, not on the first try. There was a bug in @agent_device (the lib I use for connecting agents to remote devices). Devin found it, fixed it, and sent me a PR.

Pretty wild.

[Agent Device @agent_device]

Super excited about this!

Time to move mobile development into cloud, the more options we have the better

[Michał Pierzchała @thymikee]

AI agents can now connect to real cloud devices🔥

agent-device now supports BrowserStack and AWS Device Farm.

Test, inspect, and debug on real devices in cloud instead of stopping at local simulators.

» agent-device connect browserstack
» agent-device connect aws-device-farm

What is Redraw for if you already have Skia? In the conversation with @lukebfarrell, @wcandillon breaks down the difference: Skia for scalable graphics and layout, Redraw for physics-based rendering and effects that go further. He also gets into Vision Camera, AR-style scenes, and making Redraw solid enough for real apps ⬇️

Your agent is only as useful as its feedback loop.

Mike Grabowski’s (@grabbou) @ReactSummit 2026 talk shows the fix: Agent Device gives AI coding agents a way to inspect UI, interact with the app, collect evidence, and verify changes across mobile, TV, and desktop.

@piotrgraczykk @jkasprzyk17 Love it!

[Piotr Graczyk @piotrgraczykk]

react-native-better-maps v1.0.0 is live 🚀

A faster, modern alternative to react-native-maps, built with Nitro Modules.

Shoutout to @agent_device it helped a lot during perf iteration.

Built with @jkasprzyk17

📦 npm install react-native-better-maps

@thymikee My machines make me wait sometimes while they run/debug/fix my react-native-macos apps with agent-device ❤️

How to build Android emulator cloud for AI agents

1. Create new droplet
2. Install Android SDK
3. Create Android Emulator
5. Run: agent-device proxy
6. Share auth token with agents using agent-device
7. There’s no 4.

[OpenAI Developers @OpenAIDevs]

You can now spin up a persistent cloud development environment in one prompt with the @DigitalOcean plugin for Codex.

It runs in your DigitalOcean account and keeps working when you step away.

[Agent Device @agent_device]

@callstackio pretty cool @expensify ngl

[Callstack Engineers @callstackio]

After a mobile agent writes the code, how does it verify the app? @thymikee and @lukebfarrell talk through the workflow and where @agent_device fits: simulator access, UI checks, logs, and a second QA pass when teams want it ⬇️

[Michał Pierzchała @thymikee]

Remote iOS Simulator control from a Linux agent container.

One command on the Mac:

» agent-device proxy

Here’s a remote Claude container connecting to my Mac through a cloudflared tunnel and controlling Maps on an iOS Simulator like it’s local.

[Michał Pierzchała @thymikee]

In the next version of agent-device: audio support

Your agent already has "eyes" and "hands". Now it will have "ears" too.

PSA: React Native Best Practices skill just got a big upgrade:

→ agent-first profiling via @agent_device and @callstack/inspector
→ version-aware RN, @expo, FlashList, Legend List
→ fewer misleading guidance and brittle benchmarks
→ smaller footprint
