About LeiOS

LeiOS takes a Debian base and adds what you would otherwise set up by hand after installing: a polished desktop, firmware for common hardware, developer tools, and a repository for LeiOS-specific packages.

At a glance


Base	Debian 13 "trixie"
Architecture	64-bit x86 (`amd64`)
Desktop	KDE Plasma
Installer	Calamares
Kernel	Debian's stock kernel (`linux-image-amd64`)
Package manager	APT, with the Debian archive plus the LeiOS repository
Boot	BIOS and UEFI

Goals

Stability. LeiOS stays close to Debian. It uses Debian's kernel and packages and only adds packages on top through its own repository.
Performance. Sensible defaults that keep the system responsive without trading away stability.
A great out-of-box experience. Firmware from Debian's non-free-firmware area is included, so Wi-Fi, graphics and sound work on most machines straight away.
Developer ready. Tools such as git, build-essential and curl are installed by default.
For everyone. LeiOS is tuned for developers but is approachable for anyone who wants a reliable Linux desktop.

How LeiOS is built

LeiOS consists of a few projects, all developed on git.leicraftmc.de/LeiOS:

Project	What it does
Live images	The Debian `live-build` configuration that produces the LeiOS ISO, including the Calamares installer setup. See Building the ISO.
Package repository	The APT repository at `repo.leios.dev`. It serves LeiOS packages in a `testing` and a `stable` suite. See Package Management.
Repository API	The service behind the repository at `api.leios.dev`. It checks uploaded packages and publishes them to the right suite. See The Repository API.
Developer Hub	The web interface at hub.leios.dev for publishing and reviewing packages. See Developer Hub.
Website	This site, including these docs.

License

LeiOS's own software, such as the website, the Developer Hub and the repository API, is free software under the GNU AGPL-3.0. Packages that come from Debian keep their own licenses.

LeiOS is a LeiCraft_MC project.
