Ketarin is a free, open-source Windows application for maintaining a collection of setup packages.
What Ketarin is
Ketarin is a free, open-source Windows application for maintaining a collection of setup packages. It monitors webpage content for changes and downloads updated files to a location you specify. The aim is to keep installer packages ready for copying to a disc or USB, rather than update software already installed on the computer. Users can use a FileHippo-based service or create their own download rules, including rules based on regular expressions. Applications can be organized into groups and custom categories, and flexible save-path options determine where downloads go. Entries can be imported and exported using XML. After downloads, Ketarin can run custom commands, including PowerShell scripts. Its listed features also include an online database, scheduled scans, bulk app updates, custom app support, silent installation, and a portable version. It is written in C#, targets .NET Framework 4.5, and uses SQLite. The official homepage identifies version 1.8.11 as the latest release and links to a forum and tutorial. The maker describes it as open source and extensible; some shipped icons and resource images have reuse restrictions.
