developed by the Digital Equipment Corporation for their Ultrix operating system. It was released in 1985. Shortly thereafter, it became included as part of the base X Window System distribution, beginning with X10R3. Initially, it was distributed alongside two other window managers (xwm and xnwm).
In 1986, the X Window System switched to version 11 of the protocol. Only uwm was ported, so it became the only window manager for X Window System until X11R4 release, where it was replaced by twm. uwm has never been updated since.
The name originally stood for Tom's Window Manager, but the software was renamed Tab Window Manager by the X Consortium when they adopted it in 1989 (X11R4).
twm is a re-parenting window manager that provides title bars, shaped windows and icon management. It is highly configurable and extensible. twm was a breakthrough achievement in its time, but it has been largely superseded by other window managers which, unlike twm, use a widget toolkit rather than writing directly against Xlib.
Various other window managers—such as vtwm, tvtwm, CTWM, and FVWM—were built on twm's source code.
descended from uwm.
olvm / olvwm
1989 / 1996?
OPEN LOOK Window Manager was the default stacking window manager for OpenWindows, the original desktop environment included with SunOS and Solaris. Its unique characteristic is its implementation of the OPEN LOOK look and feel.
Scott Oaks developed a variant of olwm, called olvwm (the OPEN LOOK Virtual Window Manager), which implements a virtual root window with dimensions greater than those of the video display.

Developed by Tom LaStrange at Solbourne Computer (computer workstations and servers based on the SPARC microprocessor architecture, largely compatible with Sun Microsystems' Sun-4 systems) in 1990. The most important innovation of swm was the introduction of the virtual desktop. It also introduced a primitive form of session management (restoring programs in use at the time of shutdown) to X.
Derived from twm to which it adds the virtual desktop feature from swm. All of these window managers were originally written by Tom LaStrange.
Unlike most more recent virtual window managers, tvtwm models the root window as a single large space, with the physical desktop being a viewport onto that virtual root window. The user can scroll the viewport around the virtual desktop either by pressing certain keys or by clicking into a scaled down representation of the virtual desktop, the so-called panner.
Claude Lecommandeur from the source code for twm, which, inspired by HP's vuewm, he extended to allow for virtual desktops ("workspaces" in CTWM's terminology.)

wm2 / wmx
1996 / 1998
- https://github.com/cannam/wm2 - a window manager for X. It provides an unusual style of window decoration and as little functionality as comfortable. wm2 is not configurable, except by editing the source and recompiling the code, and is really intended for people who don't particularly want their window manager to be too friendly.
- Workspace - a fork of Window Maker.

Xfwm - used in Xfce, intially based on fvwm2, itself derived from twm, redesigned to minimize memory consumption, provide a 3-D look to window frames, and provide a simple virtual desktop.
derived from mwm. uses the Motif widget toolkit, normally used on Silicon Graphics workstations running IRIX.

- Sawfish is an extensible window manager using a Lisp-based scripting language. Its policy is very minimal compared to most window managers. Its aim is simply to manage windows in the most flexible and attractive manner possible. All high-level WM functions are implemented in Lisp for future extensibility or redefinition. what i wanted when using litestep

- spectrwm is a small dynamic tiling window manager for X11. It tries to stay out of the way so that valuable screen real estate can be used for much more important stuff. It has sane defaults and does not require one to learn a language to do any configuration. It was written by hackers for hackers and it strives to be small, compact and fast. It was largely inspired by xmonad and dwm.

- Matchbox - an Open Source base environment for the X Window System running on non-desktop embedded platforms such as handhelds, set-top boxes, kiosks and anything else for which screen space, input mechanisms or system resources are limited.Matchbox consists of a number of interchangeable and optional applications that can be tailored to a specific non desktop platform to enhance usability in a ‘constrained’ environment.
- xmonad is a dynamically tiling X11 window manager that is written and configured in Haskell. In a normal WM, you spend half your time aligning and searching for windows. xmonad makes work easier, by automating this.

- subtle is a manual tiling window manager with a rather uncommon approach of tiling: Instead of relying on predefined layouts, subtle divides the screen into a grid with customizeable slots (called gravities). For better understanding, the default config uses a 3x3 grid and maps each gravity to one key of the numpad. With those keys, windows can be moved directly to the desired gravity - the same can be done with tagging rules in the config. Another unique concept is the strict tagging: Unlike other tiling window managers, subtle doesn't allow weak tagging and always maps windows to virtual desktops (called views) with matching tags, regardless of the current active view.
- https://github.com/stew/tritium - a tabbed/tiling window manager. tritium is a tiling/tabbed window manager for the X Window System inspired by the ion3 window manager. It was written completely from scratch in python and shares no actual code with ion3. tritium is implemented in python using the plwm ("pointless window manager") library

- tinywm - a tiny window manager that I created as an exercise in minimalism. It is also maybe helpful in learning some of the very basics of creating a window manager. It is only around 50 lines of C. There is also a Python version using python-xlib. It lets you do four basic things: Move windows interactively with Alt+Button1 drag (left mouse button), Resize windows interactively with Alt+Button3 drag (right mouse button), Raise windows with Alt+F1 (not high on usability I know, but I needed a keybinding in there somewhere), Focus windows with the mouse pointer (X does this on its own)

- Bluetile is a tiling window manager for Linux, designed to integrate with the GNOME desktop environment. It provides both a traditional, stacking layout mode as well as tiling layouts where windows are arranged to use the entire screen without overlapping. Bluetile tries to make the tiling paradigm easily accessible to users coming from traditional window managers by drawing on known conventions and providing both mouse and keyboard access for all features. based on Xmonad
- http://hack.org/mc/hacks/mcwm - minimalist, floating window manager written using XCB, the X protocol C binding.The only window decoration is a thin border. All functions can be done with the keyboard, but moving, resizing, raising and lowering can also be done with the mouse.If you don't like the default key bindings, border width, et cetera, look in the config.h file, change and recompile.
Wind is a window manager for the X Window System. It supports virtual desktops, optional Xft font rendering, and is pretty standards compliant. It provides overlapping window management with click-to-type focus. Unlike most window managers, Wind does not have the concept of minimized or hidden windows. Instead of hiding and unhiding windows, the virtual desktops abstraction makes it easy to group similar tasks and switch between these groups instantly using convenient key bindings. Standards compliancy is a prominent goal of the project, and Wind supports almost all mandatory parts of the ICCCM and the Extended Window Manager Hints specifications. Full compliancy is expected in the next major release.
Fork of metacity, used by MATE.
Tiling, fork of i3 with touchscreen features.
- herbstluftwm is a manual tiling window manager for X11 using Xlib and Glib. Its main features can be described with: the layout is based on splitting frames into subframes which can be split again or can be filled with windows (similar to i3/ musca). tags (or workspaces or virtual desktops or …) can be added/removed at runtime. Each tag contains an own layout. exactly one tag is viewed on each monitor. The tags are monitor independent (similar to xmonad). it is configured at runtime via ipc calls from herbstclient. So the configuration file is just a script which is run on startup. (similar to wmii/ musca)

- monsterwm is a minimal, lightweight, tiny but monstrous dynamic tiling window manager. It will try to stay as small as possible. Currently under 700 lines with the config file included. It provides a set of four different layout modes (vertical stack, bottom stack, grid and monocle/fullscreen) by default, and has floating mode support. Each virtual desktop has its own properties, unaffected by other desktops' settings. Finally monsterwm supports multiple monitors setups.

Floating and tiling, per monitor desktops. Written in Go.
TTWM / Alopex
- TTWM is a minimal tiling window manager combining concepts or elements from TinyWM, DWM, and i3wm. Inspiration has also been drawn from other great tilers like MonserWM. TinyTiler is currently under 650 lines of code. In contrast to other tilers, TinyTiler does not have modes nor does have window rules. TinyTiler has only two layouts: right stack and bottom stack. These choices were by design. TinyTiler instead provides two screen sections, the master and the stack. In TinyTiler only one stack window is visibile at a time, the others have tabs in the statusbar.

- https://github.com/baskerville/bspwm bspwm is a tiling window manager where each window is represented as the leaf of a binary tree. It is controlled and configured via bspc. bspwm have only two sources of informations: the X events it receives and the messages it reads on a dedicated socket. Its configuration file is $XDG_CONFIG_HOME/bspwm/autostart. Keyboard and pointer bindings are defined through sxhkd. Example configuration files can be found in the examples directory.
Very nice and atomic.

- https://github.com/michaelforney/velox - a simple window manager based on swc. It is inspired by dwm and xmonad. velox uses tag-based window management similar to dwm. This allows you to construct your workspace by selecting a set of tags to work with. However, in contrast with dwm, windows do not have any screen associated with them; they are shown on whichever screen has their tag selected, allowing you to easily move windows between screens by selecting their tag on a different screen. This is similar to the multi-monitor workspace switching in xmonad.To ensure that we never attempt to show a window in two places at once, we have to impose several constraints. First, each window must have exactly one tag. In practice, I've found that I rarely intentionally mark a window with more than one tag anyway. Second, when you select a tag that is currently display on a different screen, the tag is first deselected from that screen.
dynamic tiling WM featuring the v-stack, b-stack, grid, fibonacci, dualstack, equal and monocle layouts out of the box. If you want to, you can add gaps between the windows as well. monsterwm-xcb fork, thus coming from monsterwm, thus coming from dminiwm, thus coming from catwm.

- Twindy - a window manager for linux (and possibly any system running an X server?) inspired byTracktion, the multitrack audio editor/sequencer for Windows and OS X. Twindy tries to apply Tracktion's workflow, where everything is on screen at once, to a window manager. As such, there are two panels, a main panel where new windows/programs open by default and may be selected using tabs, and a lower panel, which can only hold one window/program at a time.The idea is that you'll do your main work in the top panel, and use the bottom panel for a terminal, or a file manager you'd want to keep open.
