What it is

Ketarin is a free, open-source Windows application for maintaining a collection of setup packages. It monitors webpage content, identifies changed files through download rules, and saves updated installers where you specify. The aim is to keep packages ready for copying to disc or USB, not to update software already installed. Rules can use a FileHippo-based service or your own definitions, including regular expressions. Applications can be grouped into user-defined categories, with flexible save paths. Entries support XML import and export. After downloads, Ketarin can run custom commands and PowerShell scripts. Listed features include an online database, scheduled scans, bulk updates, custom app support, silent installation, and a portable version. Written in C#, it targets .NET Framework 4.5 and uses SQLite. The homepage identifies version 1.8.11 as latest and links to a forum and tutorial. Source files use GPLv2 unless otherwise stated; resource images have reuse restrictions.
