Radarr is an open-source software application that provides users with an automated way to download movies and keep their media libraries up to date. The app is available on Windows, Linux, and Mac platforms. Radarr uses the popular Usenet technology to quickly and securely download files. It can automatically search and download content as it's released, and it also has the ability to monitor for new content and notify users when new content is available. The app also supports file organization and automatic renaming of files, so users can organize their library the way they want it. Radarr also integrates with popular streaming services, so users can easily stream their movies and TV shows from the app. It also supports integration with popular media players, so users can watch their movies and TV shows on their preferred player. Radarr also comes with a web-based user interface, making it easy for users to manage their library from any device with an internet connection.
