Delta Widgets vs GKrellM

Delta Widgets is a free, open-source Windows app for creating desktop widgets without code. Its visual drag-and-drop editor supports built-in templates, layouts made from scratch, custom HTML/CSS, and widgets built from URLs. Widgets can display live time, system statistics, media information, and weather. Preinstalled options include date and time, media controls, an audio visualizer, weather, disks, RAM, CPU, and battery. Expressions and variables insert or format dynamic values in text and images. URL widgets can embed webpages, dashboards, web apps, or online tools, and are sandboxed to display external content only. An optional bring-your-own-key assistant supports OpenAI, Anthropic, Google, Ollama, and OpenRouter; the maker says provider keys are encrypted on the device. Compatibility is listed for Windows 10 and Windows 11, with Windows 10 April 2018 or later required. The download page reports anonymous install and widget-enable events through Mixpanel, without personal-data tracking. The project uses the GPL-3.0 license, with documentation, GitHub issues, and Discord support.

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.
