 Utopia HTTP is a PHP MVC based framework with minimal must-have features for professional, simple, advanced and secure web development. This library is maintained by the [Appwrite team](https://appwrite.io).
 
-Utopia HTTP is dependency-free. Any extra features, such as authentication or caching are available as standalone models in order to keep the framework core clean, light, and easy to learn.
