Is a kdrive based X server which targets a window on a host X server
Its framebuffer. Unlike xnest it supports modern x extensions (even if
Host server doesn't) such as composite, damage, randroid etc (no Glx
Support now). It uses SHM images and shadow framebuffer updates
Provide good performance. It also has a visual debugging mode
Observing screen updates.

Xephyr
Xnest is an alternative to xnest, because xnest does not provide some advanced features of modern X Server and supports proportional acceleration. In short, xephyr
Is an X server, but it is executed in an existing X server. This can be used to do many things, such as XDMCP
To connect to another host, you do not need to open another X server. For example, if you are writing a window manager
Debugging in X server will replace the existing window manager directly in the existing X server.
It is much more convenient. Xephyr provides an excellent test environment for enthusiasts who are keen to change their own window manager.
