I'm the author. Cygnus is an application installer and manager for CachyOS / KDE Plasma (Python, PySide6, GPL-3.0). The idea: one app that handles Flatpak (Flathub), AppImages, AUR, repo packages, and Debian/Fedora apps — including converting .deb/.rpm files when it's safe to. You pick which drive each app installs to (handy if you split SSD/HDD), it resolves runtimes and dependencies, verifies signatures where possible, and can roll back what it started. Nothing touches your system without showing you exactly what it'll do and asking first. It's public beta 0.2.0 — it works and I use it daily, but it's been tested on one setup (mine) and there's no independent security review yet (security model + audit guide are in the repo). Free during the beta, or build from source. Repo + screenshots: https://github.com/AbdulazizOmran/Cygnus Launch video: https://youtu.be/c-ShWA-0TWE Fun fact on how it got built: Claude Sonnet 5.5 did most of the implementation as the main executor, with Opus 5.5 advising on architecture and several Haiku 5.5 subagents handling smaller tasks. Happy to answer questions — and bug reports welcome on GitHub issues.   submitted by   /u/suhdihnih [link]   [comments]
