Some are free, while others require additional licenses. See [Optimizely Add-ons](https://world.optimizely.com/resources/net5/add-ons/) for important information about add-ons and integrations that Optimizely developed. The apps and integrations listed here require separate installation and configuration. Some of them are available for free, and some require a specific license. :::hint{type="info"} **Note** See the App Directory, ([Browse Apps & Integrations](https://www.optimizely.com/apps/all/)), your one-stop shop to find apps and integrations to your Optimizely products that increases productivity and streamlines processes to save you time and money. ::: ## Install apps Most apps and integrations involve subscribing to a service or installing NuGet packages in Visual Studio.
