# Plugins

Spark is built as a collection of plugins. Each plugin adds a specific feature set to your game and is managed through its own tabs in the Spark Editor.

Plugins are sold individually on the [Unity Asset Store](https://assetstore.unity.com/publishers/49855). See [How is Spark Distributed](/documentation/user-guide/getting-started/how-spark-is-distributed.md) for details on purchasing options.
