ClocX vs GKrellM

ClocX is a free analog clock application for Microsoft Windows. It provides 350 configurable clock faces, three antialiasing levels, and 256 transparency levels, including a mouse-over transparency option. Window controls can keep the clock on top, pin it to the desktop, prevent movement, or let clicks pass through. Alarms can show a window, play a sound, run an application, or shut down the computer. A simple calendar is included. The application supports multiple languages, including Arabic, Chinese, English, French, German, and Japanese, and can start with Windows for all users or at the current user’s login. The maker describes it as freeware without ads, spyware, adware, or toolbars. Version 1.6.0 is listed in 32-bit and 64-bit editions, supporting Windows XP SP2 and later through Windows 11. The plan costs nothing.

GKrellM is a free system-monitoring program that stacks multiple readings in one interface and supports themes matching a window manager, GTK or another theme. Its built-in monitors cover CPU, processes, disks, network interfaces, memory, swap, filesystems, uptime and internet connections. When supported by the system’s hardware and software, temperature, fan and voltage monitors can show configurable warnings and alarms. A mailbox monitor checks mbox, maildir, MH, POP3 and IMAP mailboxes, and can launch a mail reader or mail-checking program. GKrellM can also run as a client and collect data from a gkrellmd server on a remote machine. Both the program and server support plugins for specialized monitors. Builds or compilation options are listed for Linux, FreeBSD, Mac OS X, NetBSD, OpenBSD and Windows. GKrellM requires GTK, GDK and GLib; the server requires GLib and can be installed without GTK or X libraries. It is released under the GNU General Public License at no cost.
