Impressionist

Impressionist is a lightweight open-source Ruby on Rails plugin designed to log and manage page and model-level impressions within your application. It provides developers with customizable methods to record, count, and analyze impressions—distinguishing between total and unique counts—without relying on third-party analytics platforms like Google Analytics. Impressionist is flexible, supporting both ActiveRecord and Mongoid, and is best for Rails developers seeking straightforward, in-app tracking of user engagement data.
