# Previews

## Active previews

The **Previews** page lists each Task's live previews, with the columns **Task**, **Services** and **Expires in**.

Each service shows its type — "Web Service", "Private Service" or "Static Site" — and its link. Until it has a link, it shows "Provisioning…".

A preview database is shown as "Internal only — not reachable from the internet", followed by its private address.

Backend services show "Removed in <h>h <m>m", or "Being removed".

With no previews, the page shows "No active previews".

## Preview configuration

A line above the list says how previews are built:

- "Previews are built with your preview configuration (<n> variables, <m> secret files)", with **Edit in Settings**
- "No preview configuration is set, so previews are built without environment variables", with **Add them in Settings**, when none is set

## Removal

A Task's previews are removed once all its pull requests are merged or closed, about 72 hours after its last preview deploy, or when the Task is deleted — whichever comes first.

Backend services — APIs and their preview databases — are removed sooner, about 4 hours after the Task's last preview deploy.

For how previews are built, see [Tasks → Previews](/docs/tasks/previews/).
