rails: The Heart of a Ruby Web Framework with 100,000 Commits

A framework that bundles all the elements needed to build database-based web applications according to the MVC pattern. It separates the application into three layers—model, view, and controller—clarifying each one's responsibility and systematically managing business logic, data presentation, and HTTP request handling.

Active Record converts database rows into objects and allows business methods to be attached, while Action Pack routes incoming requests and generates responses in various formats. Action View renders HTML templates to handle views, and dedicated libraries such as Active Job, Action Cable, and Active Storage are also provided for email, websockets, file attachments, and rich text processing.

Each component can be used independently outside of Rails, giving it a flexible structure. Released under the MIT license, it has a broad developer community participating in maintenance, as evidenced by 58.9k stars and 23.8k forks. Its maturity and stability are demonstrated by a commit history of over 100,000.

It is essential foundational code for developers building web backends in the Ruby ecosystem or maintaining existing Rails applications. When understanding the internal workings of the framework or proceeding with customization, this repository serves as the official source code reference.
