# Introduction

> Launch and access open source platform apps hosted on NexusOne.

The Hosted Apps feature lets you launch several open source platform apps hosted on NexusOne.
This is helpful when you need to perform actions such as creating a DAG in a JupyterHub Notebook,
viewing DAGs on Airflow or viewing dashboards on Superset.

## Supported apps

You can launch the following apps on the NexusOne platform:

* [Apache Airflow](/platform-components/apache-airflow/airflow-in-nx1)
* [DataHub](/platform-components/datahub/datahub-in-nx1)
* [JupyterHub](/platform-components/jupyterhub/jupyterhub-in-nx1)
* [Superset](/platform-components/apache-superset/superset-in-nx1)
* [Ranger](/platform-components/apache-ranger/ranger-in-nx1)
* [Trino](/platform-components/trino/trino-in-nx1)

## Use cases

These examples show how teams can use each Hosted Apps on NexusOne:

* **Business intelligence**: Access Superset dashboards to visualize business metrics.
* **Data engineering**: Open Apache Airflow to monitor DAG runs and troubleshoot failed workflows.
* **Data governance**: Use DataHub and Ranger to manage metadata, data discovery, and access policies.
* **Data science and analytics**: Launch JupyterHub notebooks to explore datasets, build DAGs, run
  command-line tools, and develop AI models.
* **Interactive querying**: Use Trino to run distributed SQL queries across multiple data sources.

## Additional resources
