Expo Launches Cloud Simulators Letting Coding Agents Test Mobile Apps
Expo is rolling out Expo Simulators, cloud-hosted iOS and Android simulator environments built for coding agents, so they can install their own builds, drive the app, and record the session before requesting human review. Agents start a remote session via the eas simulator command and operate the app through agent-device, Argent, or Appium, returning screenshots, video, and a live browser link reviewers can tap through. The move closes a key loop gap for coding agents that can write mobile code but never see it run.

AI coding agents could write app code but never see the app run. Expo is rolling out cloud simulators that allow agents to test their own changes first.
In Expo Simulators, eas simulator --platform ios starts a remote session where the agent installs its build and drives it with agent-device, Argent or Appium.
Every session records the screen, so the agent returns screenshots, video and a live browser link reviewers can tap through.

🙌 Introducing Expo Simulators: cloud simulators built for agents.
Your agent runs its change on a cloud simulator or emulator and brings back the recording before it asks for your attention.
