# Site apps - Docs

Site apps enable you to easily add functionality to your site without extra code. They are injected through the `posthog-js` library or snippet and can be used to show content or banners on your site.

## Enabling apps

Head to **Data pipelines** and click the [Site apps](https://app.posthog.com/apps) tab. Here you can install official PostHog apps by clicking **\+ New site-app**.

## Available site apps

| App | Description |

| [Pineapple mode](/docs/site-apps/pineapple-mode.md) | Rain pineapples all over your product or website. Yes, really. |
