# Server Architecture The Ellie server (just "**Ellie"** for the rest of this section) is an **Elixir** program built with the **Phoenix** framework. It runs the **Elm Platform** on the local file system and then serves information about how a user is using those binaries using a **GraphQL** API managed by the **Absinthe** libraries. Ellie's business logic and application state is separated into several **Domains** which are implemented by corresponding **Adapters**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
