Appium

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.
