Merb is an alternative web framework to Ruby on Rails that is focused on being faster, lighter, and more agile. Both Merb and Rails use the model-view-controller architecture pattern and support features like object-relational mapping and templating, but Merb takes a more minimal and flexible approach by being ORM agnostic and supporting additional libraries beyond what Rails provides out of the box. The document then demonstrates building a simple CRUD application in Merb and comparing it to how it could be done in Rails.
