Duckboard vs GKrellM

Duckboard is a desktop app for turning selected website sections into live, interactive widgets arranged in dashboards. Users can capture parts of websites or build custom widgets with HTML or embed code. Its preset library contains more than 1,900 options, with examples for YouTube, X, weather and productivity tools. The site also shows dashboard examples for morning, learning, building and finance workflows, and describes the app as private by design. Downloads are available for macOS and Windows: Mac support covers Apple silicon chips M1, M2, M3, M4 or newer, as well as Intel-based Macs; the Windows download is for 64-bit Windows 10 and 11 PCs. The download page says the app is free to download and requires no sign-up or credit card. The Free plan includes one dashboard, up to three widgets and email support. Extended is a one-time upgrade costing $29 as a one-time purchase, with one dashboard, unlimited widgets and email 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.
