It brings together tools for building database-backed websites and applications, with conventions that provide a ready-made structure for common tasks.
What is Ruby on Rails?
The Ruby on Rails API documentation defines Rails as “a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.” Ruby on Rails API documentation

Ruby is the programming language; Rails is software written in Ruby that developers use to create web applications. Rather than starting with unrelated tools and wiring them together, a Rails application can draw on a coordinated set of components for common web-development work.

How does Rails’ MVC structure work?
MVC divides an application into three responsibilities. In a typical Rails request, the controller handles the incoming interaction, the model supplies relevant data or application behavior, and the view renders the response.
#1 Best Overall
- Model: Represents application data and domain behavior. Rails’ Active Record commonly connects models to database records, but a model does not have to use a database; Rails also supports ordinary Ruby classes and interfaces provided by Active Model.
- View: Renders the response presented to the user, such as a web page.
- Controller: Processes requests and user interactions, coordinating application behavior and the response.
MVC is a way to organize responsibilities, not a requirement that every application feature fit a rigid three-file pattern. Rails includes additional components that handle other parts of an application.
What does Rails include?
Rails is more than an MVC label. Its components cover database-backed models, request handling, rendering and several other common application needs:
- Active Record and Active Model: Work with database-backed records and model behavior, with support for models that do not rely on a database.
- Action Pack and Action View: Handle web requests and render views.
- Action Mailer and Action Mailbox: Support sending and receiving email.
- Active Job: Provides a framework for background jobs.
- Action Cable: Supports WebSockets and real-time features.
- Active Storage and Action Text: Provide file-attachment and rich-text capabilities.
- Active Support: Supplies utility features used throughout Rails applications.
Some core Rails components can also be used independently, outside the full framework, according to the Rails API documentation.
Why does Rails use conventions?
The Rails Guides describe Rails as opinionated software: it makes assumptions about common web-application needs and encourages a preferred way to address them. Two principles explain much of that approach:
- Convention Over Configuration: Rails supplies defaults for common choices, so developers do not have to configure every detail manually.
- Don’t Repeat Yourself (DRY): Application knowledge should have one authoritative representation instead of being duplicated in multiple places.
When a project’s needs align with those defaults, conventions can reduce repetitive setup and make the structure easier for a team to follow. When requirements differ, developers may need to customize Rails. These principles describe the framework’s design philosophy; they do not guarantee a particular development speed or outcome.

The official Getting Started guide walks through installing Rails, creating an application, connecting a database, understanding the application layout and deploying to production. Its stated Ruby and Rails prerequisites can change as the guide is updated, so check the guide’s current requirements before installing rather than treating any version number as permanent.
- Use the installation instructions in the official Getting Started guide to check prerequisites and install Rails.
- Follow the guide to create an application and connect a database.
- Explore the application layout and the framework components relevant to what you are building.
- Use the guide’s deployment section when you are ready to prepare an application for production.
Who is Rails for?
Rails is relevant to developers building web applications, especially database-backed applications that can benefit from a framework with integrated components and established defaults. Whether its conventions suit a particular project depends on that project’s requirements and the team’s preferences; the framework’s stated principles are not a head-to-head assessment against other web frameworks.
