### Checking if an application exists
For CI/CD pipelines, it may be useful to see if an application exists before creating a "review" application for a specific branch. You can do so via the `apps:exists` command:
```shell
dokku apps:exists node-js-app
```

App does not exist
```
The `apps:exists` command will return non-zero if the application does not exist, and zero if it does.
