Site apps enable you 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' -> 'Apps' on the left sidebar in the PostHog app. Here you can install official PostHog apps.
If you're self-hosting, you can install a custom app by pasting a link to its public repository, or write your own app directly in PostHog.
