Cosmic: A New Desktop Environment

Original Article ↗ Hacker News Discussion ↗

Window management & tabbed stacking

  • Noted feature: grouping multiple application windows into tabbed stacks at the WM/OS level rather than per‑app.
  • Compared to existing stacking/tabbing in Pop!_OS’s current DE, KWin, i3, Fluxbox, BeOS, and Windows tools like FancyWM.
  • Some see OS‑level handling of tabs, tiles, sidebars, and popups as a path to more consistent UX.
  • Others worry about complexity and edge cases (e.g., IDE panels, spawned windows).

Goals, architecture, and differentiators

  • Built as a new Rust‑based, Wayland‑native desktop environment, with heavy use of the iced GUI toolkit and a custom theme engine.
  • Emphasis on modularity and branding so distros can create distinct looks/experiences without GNOME’s constraints.
  • Integrated tiling and keyboard navigation are recurring selling points; several tiling‑WM users are interested if Cosmic can provide a “batteries‑included” DE with strong tiling.

Design, usability, and aesthetics

  • Some praise the look and modern tech stack; others see “generic macOS/GNOME” styling with low contrast, heavy rounding, and large padding.
  • Significant concern that buttons, scrollbars, and window focus are hard to see, echoing a broader trend of aesthetics over usability.
  • Debate over the importance of “pixel‑perfect” design vs. accessibility, scaling, and reflowable layouts.
  • Several commenters argue that good design requires specialized talent and that open‑source projects often lack sustained design leadership.

Comparison to other desktops & historical UIs

  • Compared repeatedly to GNOME, KDE, MATE, XFCE; some claim existing DEs can already be configured to do most of what Cosmic shows.
  • Some see it as “GNOME but more mac‑like”; others as “slightly restyled MATE,” a characterization others strongly dispute.
  • References to historical UIs (BeOS, OS/2 Workplace Shell, classic Mac OS, ChromeOS) as examples of deeper or more daring UX ideas.

Installation & distro integration

  • Installation guides exist for multiple distros, including Arch and NixOS; some report early experiments leading to black screens or fallbacks to existing DEs.
  • Cosmic is positioned as a GNOME alternative, especially for distros wanting more customization without GNOME’s extension‑breakage issues.

Advanced workflow concepts

  • One long subthread imagines “worksets” or contextual desktops: persistent, named collections of workspaces, apps, and layouts per activity (coding, research, kids, etc.), possibly shareable and syncable.
  • KDE “Activities” is mentioned as conceptually similar, but no indication Cosmic currently provides this.

Overall sentiment

  • Thread is mixed to negative on visuals but cautiously optimistic on the technical foundation (Rust, Wayland, iced, integrated tiling).
  • Many stress it’s an alpha and hope the toolkit, accessibility, and design mature; others doubt the need for yet another mac‑like DE.
