# Using Marketplace

Administrators can access the SonarQube Marketplace via **Administration** > **Marketplace**. The Marketplace tab is the place for keeping the pieces of your SonarQube platform up to date. It lets you:

See:

* Which plugins are installed
* Whether plugin updates are available
* Which other plugins are compatible with your version of SonarQube

Discover:

* Which other SonarQube implementations are available, to enable more features

Install:

* New plugins
* Plugin updates

{% hint style="warning" %}
A third-party website called sonarplugins.com also exists. This website is not the same as the Marketplace and is not endorsed by, affiliated with, maintained, authorized, or sponsored by Sonar.

## Setting up SonarQube to connect to the internet <a href="#setting-up-to-connect-to-internet" id="setting-up-to-connect-to-internet"></a>

Your SonarQube Community Build instance needs internet access to check for and install plugin updates. If your SonarQube is located behind a proxy, additional set up is required.

<details>

<summary>Internet sites used by the Marketplace</summary>

The Marketplace connects to <https://downloads.sonarsource.com/?prefix=sonarqube/update> to get the list of plugins. Most of the referenced plugins are downloaded from:

* <https://binaries.sonarsource.com/>
* <https://github.com/>

<summary>If your instance is secured behind a proxy</summary>

Marketplace uses HTTP(S) connections to external servers to provide these services. If your SonarQube is located behind a proxy, you must provide additional information in `<sonarqubeHome>/conf/sonar.properties` as shown below. The same properties can be used in the `https.*` form for HTTPS connections.

```css-79elbk
http.proxyHost=<your.proxy.host>
http.proxyPort=<yout.proxy.port>

#If proxy authentication is required
http.proxyUser=<your.proxy.user>
http.proxyPassword=<your.proxy.password> 
```

</details>

<details>

<summary>If your instance doesn’t have internet access</summary>

* To install a plugin, see [install-a-plugin](https://docs.sonarsource.com/sonarqube-community-build/server-installation/plugins/install-a-plugin "mention").
* You may get errors in your logs when the Marketplace tries to search for new plugins. You can stop this by updating `sonar.updatecenter.activate` in `<sonarqubeHome>/conf/sonar.properties`.

## Installing, updating, or uninstalling a plugin <a href="#performing-plugin-operations" id="performing-plugin-operations"></a>

You need the Administer System global permission to perform these operations.

To install or update a plugin:

1. Go to **Administration** > **Marketplace > Plugins**.
2. Retrieve the plugin or plugin update you want to install and select **Install**.\
   Once the download is complete, a **Restart** button will be available to restart your instance. Restarting will enable the new plugin. This restart will not take into account any change to `sonar-properties` settings.
3. Select the **Restart** button.

To uninstall a plugin:

1. Go to **Administration** > **Marketplace > Plugins**.
2. Retrieve the plugin you want to uninstall and select **Uninstall**.

## Deploying your plugin to the Marketplace <a href="#deploying-to-the-marketplace" id="deploying-to-the-marketplace"></a>

If you have developed a SonarQube plugin, you can check out the [requirements](https://community.sonarsource.com/t/deploying-to-the-marketplace/35236) for adding it to the Marketplace in the [Plugin Development community](https://community.sonarsource.com/c/plugins/15).
