# Extensions

#### **What Are Extensions?**

Extensions are modules that bring advanced features to your BuildOnHype.com applications. They allow you to add specialized functionality — from game engines and AI chat to advanced blockchain integrations — without writing custom code.

#### **Where to Find Extensions**

In your app’s **Edit** page, select the **Configuration** tab.\
A list of all extensions compatible with your app will appear under the **Extensions** section.

#### **Why Some Extensions May Not Be Available**

Each extension supports specific app types. If an extension isn’t compatible with your current app’s structure or features, it won’t appear in the list.
