# Environments

> Browse, filter, tag, and launch the Decision Control environments you have access to from the Environments page.

The Environments page lists every Decision Control environment you have access to with live counts (Units / Models / Versions), a status badge, and tag-based filters. It lives at `/environments` - reach it from the **Environments** card on the [Home page](/docs/decision-control-tower/how-to/sign-in-and-global) or the **Environments** item in the sidebar.

All how-tos on this page are available to **any signed-in Tower user** unless noted. Counts refresh automatically about every two minutes.

## How to browse environments

See all Decision Control environments and their health at a glance.

**Steps:**

1. Open **Environments** (from the Home page card or the sidebar) - the page header shows a branch icon and title **Decision Control Environments** above the environment cards.
2. Read each card's status badge (**online** / **offline**) and **Units** / **Models** / **Versions** stats.

**Verify:** Cards render with live counts; the toolbar shows "`{N} environments`".

## How to find an environment

Narrow the grid with the toolbar filters and search.

<Tabs>
  <Tab title="Filter by status">
    1. Open the **status** dropdown (defaults to *All statuses*).
    2. Choose **Online** or **Offline**.
  </Tab>

  <Tab title="Filter by tag">
    1. Open the tag multi-select in the toolbar.
    2. (Optional) Type in **Search tags…** to find a tag.
    3. Select one or more tags; use **Clear all** to reset.
  </Tab>

  <Tab title="Search by name">
    1. Type into the toolbar **Search** field.
  </Tab>
</Tabs>

**Verify:** The grid shows only matching cards and the count reads "`{filtered} of {total}`". A count badge on the tag picker shows how many tags are active.

<Tip>
  **Reset everything**

  Click **Clear filters** in the toolbar to drop status, tag, and name filters in one go.
</Tip>

3. Press <kbd>Enter</kbd> to confirm (or <kbd>Esc</kbd> to cancel).

**Verify:** A colored tag label appears on the card (and becomes available in the tag filter).

## How to remove a tag from an environment

Detach a previously applied tag.

**Prerequisites:** The environment is **online**.

**Steps:**

1. On the card, locate the tag label.
2. Click its **×** ("Remove tag `{name}`").

**Verify:** The tag label disappears from the card.

## How to launch an environment's Decision Control workbench

Jump from governance into the Decision Control authoring/management app for that environment.
