# wix preview


Creates an online preview of your built project and provides a preview URL in the console. By default, the code for your preview is hosted on Wix's servers. 

A preview URL is a link you can share with team members that allows them to preview and test your project. Each preview URL directs to a unique version of your project hosted on Wix's servers. Subsequent updates to your project won't affect any previously created versions.

>**Note:** Before previewing the project, run the [build](https://dev.wix.com/docs/wix-cli/command-reference/project-commands/build.md) command.

<blockquote class="important">

__Important:__
The `preview` command uploads your code but does not register all extensions in your app's configuration. Some extensions, such as embedded scripts, site widgets, and site plugins, won't work until you create an app version with [`release`](https://dev.wix.com/docs/wix-cli/command-reference/project-commands/release.md).

## Usage

```bash
wix preview [flags]
```
