How to choose a cloud simulator, when a local one is better, and how coding agents, CI, and reviewers use them.
Build an agent loop for mobile bugs: EAS Observe reports the error, an agent reproduces and fixes it on Expo Simulators, and a person reviews the proof.
Agentic mobile CI/CD with EAS Workflows: the agent writes the workflow, checks its change on Expo Simulators, and brings proof. A person approves the release.
Get app feedback from friends, family, and designers: pick a few testers, give each a task, share a simulator link or TestFlight build, and run rounds.
Check what App Review checks before you submit: a clean install, a working demo account, iPhone and iPad screens, and a manual release for launch day.
Start an Expo Simulators session from a Bitrise workflow, drive your iOS Simulator build with agent-device, and save screenshots and recordings as artifacts.
Start an Expo Simulators session from a CircleCI job, install your app, run checks on a cloud iOS Simulator, save the evidence, and stop the session.
Run an iOS Simulator from GitHub Actions on Linux: build with EAS, start an Expo Simulators session, drive the app, save screenshots, and stop the session.
Send a link that opens your new build on a cloud simulator in the browser. Private links open for your Expo project, and public links open for anyone.
Put the burden of proof on the agent: it brings screenshots, a video, and a link to the pull request, and the engineer decides if the proof is enough.
Compare cloud iOS simulators, Android emulators, and real-device clouds for CI and AI coding agents, and see where Expo Simulators fits.
Eight things to check before you pick a cloud simulator, and which ones matter most when a coding agent is the main user.
Local simulators are free and sit next to your debugger. Cloud simulators start from a command and scale to your agents. Here is how to split the work.
