Ruby on Rails is an open-source web application framework that emphasizes convention over configuration, automated testing, and agile development principles. It aims to make web development simpler and more efficient through conventions that standardize common tasks and practices like source control, testing, and collaboration. Rails promotes principles like Don't Repeat Yourself, test-driven development, and prioritizing working software and customer feedback over documentation.
