# wix app preview


Creates a preview of your app that you can test before you release it.

The command uploads your build output to Wix's servers as a preview and displays links to that preview. Each link installs the preview on the development site you select. A site keeps that preview until you install another one.

You can share the links with team members so they can test your app too. Each preview stays as it was when you created it, so later changes to your project don't affect it. A preview doesn't create an app version.

> **Notes:**
>
> - This command uploads your project's build output, so you must run the [`build`](https://dev.wix.com/docs/wix-cli/cli-for-apps/command-reference/project-commands/build.md) command after every change you want to preview.
> - A preview can include at most 5,000 static files.

## Usage

wix app preview
