What is Hyggshi OS? Hyggshi OS (current version: 1.4.0 "Verdant Valley", Cinnamon edition) is a Linux distribution based on Debian trixie, independently developed by a Vietnamese programmer within the HORT ecosystem.

Problem it solves: Many mainstream Linux distributions come pre-packaged with excessive unnecessary components or lack fine-tuning for a smooth, modern experience. Hyggshi OS focuses on an optimized interface Cinnamon 6.4.10, a smooth and stable installation system (Calamares), along with its own faster system tools compared to popular tools.

Key features:

• Cinnamon 6.4.10 on kernel 6.12.101, approximately 2059 curated packages
• Nexfetch — a self-developed system information display tool, approximately 3x faster than fastfetch, distributed via a separately GPG-signed APT repository
• Customized Calamares installer: slideshow, branding, package chooser
• Optimized ISO build pipeline through GitHub Actions (cache layer, squashfs compression using zstd)
• There is a Mint-based derivative to increase hardware compatibility

Who should use it: Linux users looking for a Debian-based distro with a finely tuned, stable Cinnamon interface and lightweight, fast system tools — not aimed at complete beginners but suitable for those familiar with Linux.

How to get started: Download the ISO, write it to a USB, install via Calamares installer (supports both UEFI/Legacy). Tested through QEMU/KVM. ARM64 support is planned.

What sets it apart: Unlike distributions built from community scripts, Hyggshi OS is built from its own foundation with a custom CI/CD pipeline, self-written system tools (Nexfetch), and a customizable configuration DSL (${...} interpolation) for config management.
