The record

Purpose: Kupfer is an interface for quick access to applications and their documents.
Plugins: Plugins extend Kupfer’s quick access to objects beyond applications.
Keyboard use: Kupfer is keyboard-focused and lets users configure accelerator keys for frequently used actions.
Linux availability: The maker says Kupfer is available in Ubuntu and Debian repositories and in Arch Linux’s community repository.
Source release: The site lists version v321 and a source tarball for download.
License: The project is licensed under GNU General Public License v3 or any later version.
Runtime requirements: Kupfer requires Python 3.9 or later, GTK 3.22, libkeybinder 0.3.1, Python GObject introspection, D-Bus Python bindings, and python-xdg.
Plugin dependencies: Some plugins require additional Python modules.
Running applications: The README says Wnck 3.20 is recommended; without it, Kupfer cannot focus already running applications.
Session requirement: Normal use requires an active D-Bus session bus, and only one Kupfer instance can run per user at a time.
Keyboard shortcut dependency: Kupfer can run without Keybinder if the user assigns a window-manager keybinding to the kupfer binary.
Documentation: The user guide is available as Mallard help pages in the application and on the project website, and it is translatable.
Intended users: The maker describes using Kupfer to find and launch applications and quickly access their documents.
Extendable: Plugins extend Kupfer’s quick access to objects beyond applications.
