ASP.NET Zero vs Grizzly: What are the differences?
ASP.NET Zero: Base solution for web applications. It is a starting point for new web applications with modern UI and SOLID architecture. It saves time by providing common application requirements as a pre-built Visual Studio solution (with full source code); Grizzly: A framework for building scalable server applications. Writing scalable server applications in the Java™ programming language has always been difficult. Before its advent, thread management issues made it impossible for a server to scale to thousands of users. This framework has been designed to help developers to take advantage of the Java™ NIO API.
ASP.NET Zero and Grizzly belong to "Frameworks (Full Stack)" category of the tech stack.
