## Submitting Feedback

If you encounter errors, misleading or outdated information, report it so Expo can be improved:

Preferred command:
npx --yes submit-expo-feedback@latest --category docs --subject "/preview/eas-simulator/get-started/" "<actionable feedback>"

Direct HTTP fallback:
curl -X POST https://api.expo.dev/v2/feedback/docs-send -H 'Content-Type: application/json' -d '{"url":"/preview/eas-simulator/get-started/","feedback":"🤖 Agent feedback for docs: <specific, actionable description> (<model>, <harness>)"}'

Only submit when you have something specific and actionable to report. Try to give the most context.

# Get started with EAS Simulator

Check whether EAS Simulator is available, start a remote device session, and connect to it.

> **EAS Simulator is a limited-access preview.** It is not included with paid or free plans and is currently available only to select partners. [Join the waitlist](https://expo.dev/services/simulator) if you are interested in trying it.

#### Prerequisites

##### An Expo account with EAS Simulator access

EAS Simulator access is granted directly to select partners. Check the current project's account before starting a session.

##### A linked Expo project

Run these commands from the project directory. If the project does not have an EAS project ID, run `eas init` first.

##### A recent EAS CLI

The `simulator:*` commands are experimental and hidden. [Install or update EAS CLI](/eas/cli.md) before using them.

## Expo Skills for AI agents

If you use an AI agent, install [Expo Skills](/skills.md) and ask it to use the EAS Simulator skill. The skill can perform the session workflow below, drive the app, and collect evidence for you. Use this page when you want to understand or run the commands manually.

[eas-simulator](https://github.com/expo/skills/blob/main/plugins/expo/skills/eas-simulator/SKILL.md) — Run and control a user's app on a remote iOS/Android simulator hosted on EAS cloud.

## Start a session manually

### Authenticate and verify the project

On an interactive machine, log in and confirm the current user:

```sh
eas login
eas whoami
```

In CI or a headless agent environment, provide an [Expo access token](/accounts/programmatic-access.md) in `EXPO_TOKEN` instead of starting an interactive login.

If the project is not linked to EAS, initialize it:

```sh
eas init
```

### Check account availability

The availability check is read-only. It does not start a device or consume simulator usage. The `--json` flag is optional, but it makes the result easy for an agent or script to inspect:

```sh
eas simulator:availability --json
```

An enabled account returns:

```json
{
  "available": true,
  "accountName": "my-account"
}
```

If `available` is `false`, do not call `simulator:start`. Use a local simulator or emulator, or [join the waitlist](https://expo.dev/services/simulator) for access.

### Protect the session configuration

EAS CLI writes the current session ID and controller credentials to **.env.eas-simulator**. Add the file to **.gitignore** before starting:

```sh
.env.eas-simulator
```

Do not commit or share this file. It includes the token that lets a controller reach the remote device.

### Choose a controller and start a remote device

Choose the controller you plan to use for installation and device actions. Pass its type explicitly when you start the session.

#### agent-device

See [agent-device and Expo](/agents/agent-device.md) for controller setup and commands.

```sh
eas simulator:start --platform ios --type agent-device --non-interactive
```

#### Argent

See [Argent and Expo](/agents/argent.md) for controller setup and commands.

```sh
eas simulator:start --platform ios --type argent --non-interactive
```

Use `--platform android` for an Android Emulator. Android sessions do not currently include a live browser preview.

When `--platform` is omitted in an interactive terminal, EAS CLI asks which platform to use. Non-interactive runs require the flag.

The start command waits for the selected controller to become ready, then writes **.env.eas-simulator**. It also prints:

-   A direct simulator session page on expo.dev
-   A temporary `webPreviewUrl` for supported iOS sessions
-   The command pattern for controlling the device

> `--non-interactive` does not automatically stop the session. The command returns when the session is ready, and the remote device remains active.

### Confirm that the session is active

Use the session ID from **.env.eas-simulator**:

```sh
eas simulator:get --json --non-interactive
```

Continue when `status` is `IN_PROGRESS` and `remoteConfig` is present. A stopped session can still have old connection configuration, so the dotenv file alone is not proof that the device is live.

### Open the web surfaces

The start command links to a session page with this shape:

```text
https://expo.dev/accounts/<account>/projects/<project>/simulator-sessions/<session-id>
```

The project-level session list is:

```text
https://expo.dev/accounts/<account>/projects/<project>/simulator-sessions
```

For supported iOS sessions, open `webPreviewUrl` in a desktop browser to view and interact with the live simulator. The preview URL is not an application deep link. Do not pass it to a controller command that opens apps or URLs.

### Stop the session

When you finish, stop the current session:

```sh
eas simulator:stop
```

If you started EAS CLI without `--non-interactive`, it remains attached. Press Ctrl+C once to stop the session and let EAS CLI reset **.env.eas-simulator**.
