# Run analyses and applications

## Create an Application

<mark style="color:$primary;">**Outcome**</mark>\
You add a new application (JupyterLab, RStudio, MATLAB, VS Code, or similar) to an instance in your project.

<mark style="color:$primary;">**Before you start**</mark>

* You are an **Instance Editor** or **Space Administrator** of the target instance.
* You are in the Current state of the instance.
* You know which application type you need.

#### Add the Application

{% stepper %}
{% step %}
Navigate to the space and the instance.
{% endstep %}

{% step %}
Make sure you are in the **Current state**.
{% endstep %}

{% step %}
On the sidebar, click the screen icon (**Applications**) to open the Applications list.
{% endstep %}

{% step %}
Click **+ ADD NEW APPLICATION** in the top left.
{% endstep %}

{% step %}
In the Application Marketplace, find the Application you want.
{% endstep %}

{% step %}
Click **+ INSTALL**.
{% endstep %}
{% endstepper %}

For all available Applications, their resource sizes, and the full configuration options, see [Reference › Applications](/reference/applications.md).

## Start an Application

<mark style="color:$primary;">**Outcome**</mark>\
You launch an application and open it ready for use.

<mark style="color:$primary;">**Before you start**</mark>

* The application has been added to an instance you have access to.
* You are signed in to Nuvolos.

The procedure for starting an application is the same regardless of the role. See the canonical procedure: [How-to › Common Workflows › Starting an Application](/how-to-guides/common-workflows/starting-an-application.md#starting-an-application).

{% hint style="info" %}
Application startup typically takes 30–60 seconds. The first start of a newly created Application may take longer if dependencies are still being initialised.
{% endhint %}

## Stop an Application

<mark style="color:$primary;">**Outcome**</mark>\
You stop a running application to free up resources and stop accumulating NCU or Credit consumption.

<mark style="color:$primary;">**Before you start**</mark>

* You have a running application you want to stop.

Stopping applications when you are done is good research-budget hygiene: you stop consuming resources you do not need. The procedure for stopping an application is the same regardless of the role. See the canonical procedure: [How-to › Common Workflows › Stopping an Application](/how-to-guides/common-workflows/stopping-an-application.md).

{% hint style="info" %}
Nuvolos auto-stops idle applications after 6 hours (Included sizes) or 1 hour (Credit-based sizes) in research spaces. Stopping explicitly frees resources sooner. The inactivity limit can be configured per application - see [Reference › Applications](/reference/applications.md).
