Ketarin review
A flexible open-source choice for maintaining custom Windows installers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ketarin is an open-source Windows desktop application for monitoring software download pages and maintaining current setup packages. It suits power users, administrators, and technical teams that need to collect installers locally, apply custom download logic, and keep installation files organized. The tool can monitor web pages for changes, download updated packages, and store files in specified locations. It is designed for installer maintenance rather than direct updates to software already installed on a computer.
Its main strength is the control it gives over custom workflows. Users can define download rules with regular expressions, use predefined setup instructions, copy files, and run custom commands after downloads. Silent installations and command-line options support repeatable deployment tasks, while batch, C#, and PowerShell scripts extend the workflow for more involved operations. Applications can be grouped into user-defined categories and installation lists, and profiles can be imported or exported as XML. These features make Ketarin a practical fit when standard update catalogs do not cover a particular application or download page.
Ketarin also fits portable maintenance workflows: it runs without installation and can use a database from a USB drive. Bulk operations, custom application support, and scheduled scans add useful range, with scheduled operation handled through command-line use. Its focus is deliberately narrow, however. The platform is Windows-only, and the documented integration is FileHippo. It also maintains setup packages rather than acting as a general installed-software updater. Choose Ketarin when custom rules, scripts, silent installs, and local installer storage matter more than a broad cross-platform catalog. Choose an alternative if you need macOS or Linux support, direct application updating, or a wider integrated ecosystem.
