This page consolidates links to the latest demo videos that cover some projects that are built using arcan.

Cat9 (2022+):

Cat9 is a command line shell that relies on the TUI API found in Arcan and provides a migration path away from the legacy of terminal emulation. As such it can provide substantially better command line experience across the spectrum, from performance and latency to features, discoverability and general user friendliness.

Pipeworld (2020+):

“Pipeworld” is in the deep end of the experimental pool, and blurs the line between terminals, desktops and applications as a spreadsheet desktop environment. It comes with something as uncommon as a zooming-tiling window management scheme, and provides an answer to the question that practically nobody ever dared to ask – “What happens if
all of your desktop is squeezed into the workflow and processing model from Excel?”.

Durden (2015+):

Durden is a feature heavy desktop environment that heavily expands upon the workflow and ideas from projects like awesomeWM and i3, with a long range of unique and useful features. Its core covers most, if not all, components in order to be configured into mimicking any popularised desktop workflow. More on this project is covered on its own webpage, at

Prio (2017):

Prio is a small mouse- oriented desktop environment that expands on the ideas and workflow presented by Plan9 Rio. As such, it has a smaller footprint and much smaller codebase than Durden. It’s intended for customization jobs and as a learning platform, but can easily work as your terminally oriented Raspberry-Pi class hardware DE.

Safespaces (2018+):

Safespaces explores how desktop environment concepts could be translated into both a normal “first-person” 3D experience, and into the much more powerful Virtual-Reality space when using a HMD and other devices.

Senseye (2014+):

SensEye is an experimental reverse- engineering and debugging platform using data exploration through visualisation techniques as a glue to connect more traditional methods.

AWB (2012-2013):

AWB is a discontinued desktop environment that tried to mimic the look and feel of the Amiga Workbench (1.3) mixed with tricks from the (relatively speaking) more modern BeOS and some extra things of our own. It was instrumental in finding rough spots when evolving the API.
