Dux Modular Shell: free desktop shell with dynamic theming and companion apps
Dux Modular Shell is introduced on its own landing page, duxlabs.dev, as "a modern and beautiful desktop shell with dynamic theming and smooth animations." The page pitches it as a complete desktop experience out of the box.
The shell itself puts media controls, weather, a calendar and system info at a glance, and gives controls for audio, displays, network and bluetooth. It can be personalised, and the page says functionality can be extended with new widgets, launcher features and more.
Around the shell sits a set of companion tools, all described in the project's own words. There is a fast, keyboard-first file manager with tabs, split view, search, trash, devices and network shares. There is a stateless system and process monitor covering CPU, memory, GPU, disks and network interfaces. There is a greetd greeter, a file system search tool billed as blazingly fast and efficient, and a calendar and tasks app that brings calendars, events and tasks together with Google, Microsoft, CalDAV and iCloud support.
Theming is the central feature. Dux Modular Shell automatically generates matching colors for supported GTK and Qt apps, terminals, editors and more. For terminals and syntax highlighting, a custom algorithm called dank16 builds a full 16-color palette, with contrast tuned for light and dark themes.
On price, the page says the shell costs nothing to use. If it has earned a spot on a user's desktop, it asks for a tip to help cover the time and infrastructure that keep releases coming.

Why it matters
Dux bundles a shell and a set of everyday desktop tools into one package, with color theming applied across them. The pitch is a complete desktop experience out of the box, rather than a shell that leaves the user to assemble the surrounding apps. The theming part is the most specific: one palette, generated automatically, reaching GTK and Qt apps, terminals and editors.
Who it affects
The page speaks to people who want a polished, ready-to-use desktop, especially those who care about consistent colors across toolkits and terminals. The file manager is aimed at keyboard-first users. The calendar app is relevant to anyone who needs Google, Microsoft, CalDAV or iCloud calendars on the desktop.
How to use it
The shell costs nothing to use, and the page asks for a tip if it has earned a spot on your desktop. Theming covers supported GTK and Qt apps, terminals, editors and more, and widgets and launcher features can be added to extend it. The page text gives no download link, repository URL or tip amount, and lists no supported distributions, compositors or system requirements.
How solid is it
Everything here comes from the project's own landing page, so the descriptions are self-claims. "Fast" and "blazingly fast" are self-descriptions, and no benchmarks or performance figures are given. No license is named. No authors, maintainers or company are named. No version number, release date or changelog is given.
Risks and caveats
Automatic theming covers only supported apps, so some software may not match. The page text does not name a license or the people behind the project, and gives no version or release history. The project relies on tips to fund its time and infrastructure.
