I built Super ISO Updater (SISOU), a tool that keeps bootable ISOs on a Ventoy drive automatically updated.

This project started a few years back because I got tired of manually checking for new releases of the various troubleshooting tools and installers I kept on my Ventoy drive.

SISOU automates checking for updates, downloading them, verifying the downloads, and storing everything in a neatly-sorted directory structure.

It’s open source (GPL-2.0-or-later), written in Python, and works on both Linux and Windows.

One note: on Python 3.14, libtorrent currently needs to be installed through your system package manager (or built manually), since upstream hasn’t published on pypi yet. On Arch Linux, the package is libtorrent-rasterbar.

I would love to hear what you think. You can try it out by installing `sisou` using pip/pipx/uv. Issues and PRs are welcome!
