Rails

Full-stack web application framework written in Ruby that favors convention over configuration. Delivers a complete stack for building web apps with integrated tools for databases, templating, routing, background jobs, email, WebSockets, and security.

Ruby on Rails powers production apps at GitHub, Shopify, Airbnb, Basecamp, and hundreds of thousands of others. Over six thousand contributors have shaped the codebase. It distinguishes itself from lighter frameworks by bundling an opinionated structure, Active Record ORM, and built-in features so teams spend less time on wiring and more on domain logic.

Key capabilities:

• Active Record ORM with associations, callbacks, encryption, and rich SQL query expression
• Action Controller and Action Dispatch for request handling, routing, and caching
• Action View with ERB templates, helpers, and direct domain model access
• Built-in email delivery, WebSockets, and background job queuing
• Hotwire as the default front-end for modern interactivity without heavy JavaScript

Rails fits web apps that benefit from strong conventions and integrated tooling, from MVPs to large-scale products. Developers use it for SaaS backends, APIs, content platforms, and e-commerce. The framework ships with security protections for common attacks and integrates with databases, cloud storage, and deployment workflows.
