Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, Django takes care of much of the hassle of web development, allowing developers to focus on writing their apps without needing to reinvent the wheel. It follows the model-template-view (MTV) architectural pattern, which is similar to MVC. Django is known for its "batteries included" philosophy, providing a comprehensive set of tools and features out of the box, including an ORM, authentication system, admin interface, and more.

Yii (Yes It Is!) is a high-performance, component-based PHP framework for developing modern web applications. It implements the MVC architectural pattern and is designed to be efficient, feature-rich, and easy to extend. Yii is known for its performance optimization techniques, security measures, and extensive set of features including input validation, output filtering, and authentication. It also provides tools for rapid application development, making it popular for both small and large-scale web projects.

Google Web Toolkit (GWT) is an open-source set of tools that allows web developers to create and maintain complex JavaScript front-end applications in Java. GWT emphasizes reusable, efficient solutions to recurring Ajax challenges, allowing developers to create high-performance web applications without being experts in browser quirks, XMLHttpRequest, or JavaScript. It includes a Java-to-JavaScript compiler, a robust set of widgets and panels, and tools for optimizing and tuning applications. While not as widely used as it once was, GWT still has a place in enterprise Java development.

Ruby on Rails, often simply called Rails, is a server-side web application framework written in Ruby. It's designed to make programming web applications easier by making assumptions about what every developer needs to get started. Rails follows the model-view-controller (MVC) pattern and emphasizes the use of well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern. Rails is known for its ability to help developers build websites and applications quickly, with clean and pragmatic design.

ASP.NET is a robust, open-source, server-side web application framework developed by Microsoft. It's designed for building dynamic web pages, web applications, and web services. ASP.NET extends the .NET developer platform with tools and libraries specifically for building web apps. It supports multiple programming languages, including C#, F#, and Visual Basic, allowing developers to create scalable and high-performance web applications. ASP.NET offers various frameworks like ASP.NET Web Forms, ASP.NET MVC, and ASP.NET Core, catering to different development approaches and requirements.
