What Ketarin is

Ketarin is a free, open-source Windows application for keeping a collection of setup packages updated. It watches webpage content for changes and downloads files to a chosen location, so installers can be copied to disc or USB; it is not intended to update software already installed on a computer. Users can choose a FileHippo-based service or define download rules, including regular expressions. The application overview supports groups and user-defined categories, and save paths can be configured flexibly. Entries can be imported or exported as XML. After downloads, Ketarin can run custom commands, including PowerShell scripts. Its listed capabilities also include an online database, scheduled scans, bulk app updates, custom app support, silent installation and a portable version. The program is written in C#, targets .NET Framework 4.5 and uses SQLite. The homepage identifies version 1.8.11 as the latest version and links to a user forum and tutorial. The maker describes the application as extensible; the repository license specifies GNU General Public License version 2 for source files unless otherwise stated, while resource images may not be redistributed.
