# Organizations

## What is an organization?

In Cortex, your organization (org) is your private Cortex environment. Only you and those you allow have access to this environment and the data within it.

## Organization environments

### Production

The Medable production environment has active end-users and is for storing critical and/or sensitive data.

Production environments are accessed from the following endpoints:

* **Admin UI:** `https://app.medable.com`
* **API:** `https://api.medable.com`

### Development

The Medable development environment is used for active app development and testing without impacting production environments. It's your own container to configure to your liking. Later as you progress from deployment to production, you might even request a staging or production environment to fit your development cycle.

Development environments are accessed from the following endpoints:

* **Admin UI:** `https://app.dev.medable.com`
* **API:** `https://api.dev.medable.com`

{% hint style="info" %}
**Note:** Critical or sensitive data should not be stored in development environments, as these environments do not employ all of the necessary protection safeguards.

### QA

QA environments are accessed from the following endpoints:

* **Admin UI:** `https://app.qa.medable.com`
* **API:** `https://api.qa.medable.com`
