# Trackers

A tracker is a scoped version of Google Issue Tracker used by some open source
projects. A tracker view shows only issues and components that belong to the
tracker, letting you focus on work that is relevant to your project. Trackers
can also have custom branding with a unique URL, logo, and color theme.

## Features

Trackers include several features:

- You can access a tracker from a custom domain. For example, you can access
  the Pigweed tracker from
  <https://issues.pigweed.dev>.

- You see a branded instance of Google Issue Tracker. For example, the Pigweed
  tracker shows Pigweed logo and header, open source themed buttons, and a
  footer with Pigweed branding.

- You only see [issues](https://developers.google.com/issue-tracker/concepts/issues) and [components](https://developers.google.com/issue-tracker/concepts/components) belonging to the
  tracker.

  > [!NOTE]
  > **Note:** Although autocomplete suggestions only show issues that belong to the tracker, you can add issue dependencies from outside of the tracker by specifying the Issue ID. For example: You can still use blocking and blocked by to reference an issue that is external to the tracker. For more information, see [Blocking an issue](https://developers.google.com/issue-tracker/guides/block-issue).

- Tracker admins can configure trusted **collaborator groups** . Issue admins
  can add these groups as **collaborators** on issues from the
  [issue access limits](https://developers.google.com/issue-tracker/concepts/issues#issue_access_limits)
  dialog:

- Alternatively, issue admins can add trusted **collaborator groups** to
  issues on the create issue page:

## Access non-tracker issues from a tracker

You can access your [hotlists](https://developers.google.com/issue-tracker/concepts/hotlists), [saved searches](https://developers.google.com/issue-tracker/concepts/saved-searches) and
[bookmark groups](https://developers.google.com/issue-tracker/concepts/bookmark-groups) when using a tracker. However, some issues
may not be visible, since issues outside of the tracker are not displayed.

When you view an issue not belonging to the tracker, you will be redirected
outside the tracker.

## View tracker information

When you are not in a tracker, tracker chips are displayed for issues and
components belonging to a tracker.

When you view a tracker issue from outside of a tracker, you see a banner with a
link to view the issue in the tracker.

You can search for issues by tracker using the `trackerid` field in the search
bar.
