# Who can open it

> Every app starts private. Four settings, and what each one means.

```bash theme={null}
bay share my-app                 # where it stands now
bay share my-app public          # change it
```

<CardGroup cols={2}>
  <Card title="private" icon="lock">
    Only you. Every app starts here.
  </Card>

  <Card title="shared" icon="user-plus">
    You, plus the people and domains you invited.
  </Card>

  <Card title="workspace" icon="users">
    Everyone in your workspace.
  </Card>

  <Card title="public" icon="globe">
    Anyone with the link, no sign-in.
  </Card>
</CardGroup>

## Inviting people

```bash theme={null}
bay share my-app add ada@acme.com     # one person, who gets an email
bay share my-app add @acme.com        # everyone with an address at that domain
bay share my-app remove ada@acme.com
```

## What a visitor cannot see

The [X-ray](/concepts#x-ray) — what the app is doing, what happened to it, who is
in it — belongs to the owner. So does the Room. A person you sent a link to
during a build gets a page with no build on it, not the same page with the
details switched off: it is a different page, so there is nothing for a future
edit to accidentally re-enable.
