# Sharing scanners

> Share a scanner page by a public link, open someone else's scanner view only, clone it as your own copy, or follow it so your page mirrors the owner's saved filters.

A scanner page can be opened by a public link. The owner decides when to share and when to stop. Sharing, cloning and following need an account, a guest can only view.

## Share by link

1. Hover the page in the sidebar and click **⋯**.
2. Click **Share by link**. The page shows the badge **Shared by link**, and anyone with the link can open this scanner, view only.
3. Click **Copy link** to copy `/scan/<code>`.
4. **Stop sharing** closes the link again.

A page that follows another scanner cannot be shared.

## Opening someone else's scanner

The link opens the scanner with the owner's filters, view, columns and hidden pairs. The breadcrumb says **Shared** and the top bar shows the badge **View only**: filters can be changed here, but nothing is saved and no pairs can be hidden. **Reset** returns to the owner's state. Two buttons stay: **Follow** and **Clone to my scanners**.

If the owner stopped sharing, the page says **This scanner is not shared with you**. A wrong code gives **There is no such scanner**.

A shared scanner opened by link: view only, Follow and Clone.

## Clone

**Clone to my scanners** asks **Clone "name"?** and creates a copy with its filters, view and hidden pairs in your scanners. You can rename or delete it later. The original stays with its owner and will not change. When the name is taken, the copy is called `name (clone 1)`, `name (clone 2)` and so on.

## Follow

**Follow** asks **Follow "name"?** and creates a page that mirrors the shared scanner: its filters and view update whenever the owner saves changes, and alerts bound to it follow along. The page shows **Following · View only**. You cannot edit it, but you can rename, delete or clone it.

If the owner stops sharing or deletes the scanner, the page shows **Source closed** and keeps the last seen filters frozen. **Stop following** in the page menu keeps the page with its current filters as your own editable page.

A page you follow counts toward your page limit. A page that follows another scanner cannot be followed or shared in turn.
