webapp2 vs Apache Sling: What are the differences?

Developers describe webapp2 as "Lightweight Python web framework compatible with Google App Engine’s webapp". webapp2 is a simple. it follows the simplicity of webapp, but improves it in some ways: it adds better URI routing and exception handling, a full featured response object and a more flexible dispatching mechanism. On the other hand, Apache Sling is detailed as "Innovative web framework that is intended to bring back the fun to web development". It is a framework for RESTful web-applications based on an extensible content tree. It maps HTTP request URLs to content resources based on the request's path, extension and selectors. Using convention over configuration, requests are processed by scripts and servlets, dynamically selected based on the current resource. This fosters meaningful URLs and resource driven request processing, while the modular nature of Sling allows for specialized server instances that include only what is needed.

webapp2 and Apache Sling belong to "Frameworks (Full Stack)" category of the tech stack.

Some of the features offered by webapp2 are:

• Compatible with webapp
• Compatible with latest WebOb
• Full-featured response object

On the other hand, Apache Sling provides the following key features:

• REST based web framework
• Content-driven, using a JCR content repository
