Laravel is a free, open-source PHP web application framework designed for the development of web applications. It follows the Model-View-Controller (MVC) architectural pattern, which separates an application into three main components: the model (which represents the data), the view (which represents the user interface), and the controller (which handles the input and output).

Laravel provides a range of features to make web development easier and more efficient, including an ORM (Object-Relational Mapping) for interacting with databases, a templating engine for building dynamic views, and a command-line interface for managing projects. It also has support for unit testing and integration testing, and is designed to be scalable and maintainable.

Laravel is widely used for building a variety of web applications, from small websites to large, complex applications. It is supported by a large community of developers, with a wealth of resources and documentation available online.
