## What it is
Ruby on Rails is a full-stack MVC web application framework written in Ruby, bundling Active Record ORM, Action Pack routing/controllers, Action View templating, and libraries for email, background jobs, WebSockets, and file storage. It is designed for rapidly building database-backed web applications following convention-over-configuration principles.

## Use cases
- build a database-backed web application in ruby
- rapidly prototype an mvc web app
- build a crud application with an orm
- add websockets to a ruby web app
- send and receive email in a web application
- run background jobs with a queuing backend
- build a rest or json api in ruby

## When to choose
- you want a batteries-included full-stack framework with strong conventions
- you are building a database-backed web application in Ruby
- you need ORM, routing, templating, jobs, and email out of the box
- you value rapid development and a mature ecosystem

## When to avoid
- you need a microframework or minimal API-only setup with tiny footprint
- your stack is not Ruby
- you need fine-grained control over every architectural decision
- you are building a lightweight static site

## Facets
- artifact type: framework
- maturity: stable
- function: web-framework, orm, templating, routing, websocket, email, file-upload
- domain: web-development, backend, databases
- platform: ruby, cross-platform
- tags: mvc, activerecord, full-stack-framework, convention-over-configuration, activejob, actioncable, background-jobs, full-stack, web-server
