History

 code was used for rewrite. The last release by the original author came out in August 2005.

In April 2007 the cwm was imported into OpenBSD source tree. By January 2008 substantial part of the original source code (including all of the 9wm code) was rewritten.

Currently cwm is distributed with OpenBSD since release 4.2, where it replaced wm2

Description

cwm is a stacking window manager oriented towards heavy keyboard usage, small footprint and ease of use. While it lacks explicit virtual desktops functionality, it can be emulated by using the window groups mechanism. cwm doesn't draw window decorations except for 1 pixel border around the windows.

cwm includes several menus:
  • exec menu (application launcher)
  • window menu (searching windows of running applications)
  • ssh to menu (start a Secure Shell

Reception

cwm is generally positively received in software minimalist communities and is totally ignored by most other computer users.

Though not reviewed separately, cwm is noted to be used mainly due to its status of one of the default window managers in OpenBSD, though other reasons are sometimes cited, such as being out of the ordinary or allowing nice interaction with GUI. Though it often gets no explanation, several OpenBSD users prefer to use cwm under Linux, even if it requires modifying and supporting source code. cwm is also praised for its flexibility, ability to interact in non-disruptive way and no dependency on mouse.
