## What it is
A Ruby gem that provides easy activity tracking for ActiveRecord, Mongoid, and MongoMapper models in Rails 6.1+. It records what has been changed or created and lets you present those activities to users, similar to GitHub's activity feeds.

## Use cases
- track model changes in a rails app
- build a github-style activity feed
- record user actions on activerecord models
- show a news feed of recent activity
- audit trail for model create update delete
- activity stream for mongoid models

## When to choose
- you need user-facing activity feeds or model change tracking in a Rails app
- you want a mature, drop-in gem with ActiveRecord, Mongoid, and MongoMapper support
- you want customizable activity views, layouts, and I18n out of the box

## When to avoid
- you need full event sourcing or versioned snapshots rather than simple activity records
- you are not using Rails or an ORM it supports
- you need high-throughput event streaming rather than per-model activity logging

## Facets
- artifact type: library
- maturity: active
- function: logging, orm, middleware
- domain: web-development, backend, developer-tools
- platform: ruby
- tags: activity-stream, activerecord, mongoid, news-feed, rails-gem, audit-tracking, web-server
