# Software factory: Share a preview link

Send a client a link to an app you are still building. The link stays on until you turn it off.

---

You can send anyone a link to an app you are still building. They click
through the draft in their browser. They do not need a Chipp account, and
opening the link publishes nothing and costs you nothing.

## A link stays on until you turn it off

A preview link has no end date. Send it once and it still works days or weeks
later. You do not need to make a new link or send it again.

You end a link yourself with **Turn off**. It stops working on the person's
next page load.

## Make a link

1. Open the draft in the Builder.
2. Choose **Share** on the preview, then **Create link**.
3. The link is copied. Paste it into an email or a message.

The first choice, **Until I turn it off**, is the default. If you want a link
that ends by itself, pick a time instead: 1 hour, 24 hours, 3 days, 7 days or
14 days. The list shows each link's end time.

## Copy a link again

Every link that is on has a **Copy link** button in the list. Use it any time
you need the same link again. It copies the same address each time.

**Open in new tab** on the preview uses the same link, so opening the preview
twice does not make two links.

## Turn off or replace a link

- To end a link, choose **Turn off** next to it.
- To replace a link, choose **Create link** for a new one, then **Turn off** the
  old one. Each client can have a link of their own, so turning one off does not
  affect the others.

Anyone who has a link can open it, so send it only to people you want to see
the draft.

## When the draft is asleep

A link opens the draft's preview. A draft goes to sleep when nobody is working
in it, to save cost. When it is asleep, the person who opens your link sees a
page that says the preview is asleep. They cannot wake it. Open the project in
the Builder to wake it, and their next page load works.

A draft also ends after seven days. After that the link shows a not-found page.
To share a finished app for longer, publish it. The published address works
without the draft.
